#AtoZChallenge2021: O is for Orc, Desert

Given I kicked off this whole idea with a detailed round-up of the Orc across the editions, it behooves me to at least stat one up.  But which one?  I have a few.  In truth, there is one I have been sitting on for long while now and I should pull it out for a special occasion.  I think that day is today.  Plus I have done so many water-based creatures, time for something different.  

So here is a monster that I talked about in the first days of this blog nearly 12 years ago! The Desert Orc.

Orc, Desert

He was an orc. That was obvious. Though there was something different about him and the others.  What I had originally taken to be smaller, younger orcs were in fact elves. Orcs and elves! Traveling together across this great expanse of desert. More than that, they acted as if they were kin!  They invited us to their tents where one orc and one elf who referred to each other as “brother” went about an elaborate tea ritual where we were served first. The orc and the elf then presented to each other their cups of tea in something akin to prayer or benediction. Once they drank they turned and smiled at each other. Ritual satisfied, they turned to us. The orc, Nom’dosh Thurgash and his elven brother Nom’dosh Etain, both greeted us in the most cultured elven I have heard outside of the Silver Forests.

“Welcome fellow travelers. How may the humble members of the Nom’dosh Clan aid you?”

Desert Orcs appear to be normal orcs. However, these orcs have more than just a glint of intelligence in their eyes. While their faces are still animal-like, the fierce scowl has been replaced with a stoic set to their jaw, a purpose in their eyes, and a bearing that can't be described as anything else but noble.  These orcs, with their sandblasted faces and long pale hair strike you as something new and different. 

Desert Orcs are nomads, their ancestral homes in the deserts were destroyed centuries ago by humans. Though they fought back and shook off the yokes of slavery and tyranny by the humans.  They travel with the only other people that helped them in their great revolution, the desert elves.  Desert elves and desert orcs now consider themselves as one people.  They are brothers and every clan has orc and elf members that are equal in all things. 

Once united they then discovered that they had skills that were mutually beneficial to each other. Orcs are still militaristic with small war cadres connected to powerful elf families. For an orc, it is an honor to serve since the more powerful the elf family the stronger their own cadre is respected. The stronger the orc cadre, the more respected the family is and the more likely they will get goods to trade. An elf sultan will travel without his wife for example, but never without his orc escorts.

For every 10 desert orcs, there will be a cadre leader of the 2nd to 4th level.  For every 50 there is an additional war chieftain of 5th to 7th level. For every 100 there is a marshall and for larger groups a general.  Cadres will still fight against each other in mock skirmishes, and while damage will be done they are rarely fatal.  A desert orc will never raise a blade against an elf and likewise, a desert elf will never raise a blade against a desert orc.  Over 1000 years of mutual respect and fighting side by side has torn down the ancient hatred that has infected their rest of their brethren worldwide.

Tea Ritual

There is a ritual that all desert orcs and desert elves will practice.  When camp is made the sultan of the elves and the war chieftain of the orcs will meet in their open tent. The sultan will help the chieftain remove his armor while the war chieftain prepares the tea.  When both tasks are complete, and to do this correctly requires practice so both are done at the same time. The sultan and the chieftain offer each other the tea with the renewed promise that their lines will continue to fight and honor each other. Then the remaining elves and orcs will complete their camps.  If guests are present then they are served first but no elf or orc are allowed to drink until their respective leaders complete their oaths and drink.

The only species they truly distrust are humans. They both recall the tales of depredations at the hands of the Necromancer Kings.  Although humans approaching their camps or caravans with respect will be heard.

--

Ok. So yeah I did it. I made "Good" Orcs.  In fact, I made them 12 years ago.  I also did "Good" kobolds.

Orcs are like Klingons.  Yes, they were two-dimensional and evil in the TOS days, but now we are in the Next Generation and Orcs can be more.  Are violent? Of course! Do they still kill people? They sure can!  Are they inherently evil?  No. Not these orcs.  I have other orcs that are every bit as evil as are demons, but individuals can and do vary.

Likewise I am almost at a point in my games where Drow are going to split off into two separate factions, the evil demon-worshipping one and a less evil faction that wants reunification with the other elves.  

So if Orcs are my Klingons, then to use a metaphor I have been using since the early 80s, elves and drow are my Vulcans and Romulans.  Just like them the Vulcans and Romulans are now a new species, the Nivar.  I don't have a name yet for my combined elves.

I am also adding an occasional bit to some entries, "From the Journal of Larina Nix." Or how these creatures are from the point of view of an adventurer.  I figure my iconic witch is as good as any to present these details.

#AtoZChallenge2021: N is for Nuckelavee

Much like the Merrow, this creature has been rummaging around in the back of my mind for the better part of 25 years.  I just never could get it the way I wanted it. I think today is that day! One of the true monsters of Celtic myth and legend, I present to you the Nuckelavee.

Nuckelavee by James Torrance (1859–1916)
Nuckelavee
Large Monstrosity (Aquatic)

Frequency: Very Rare
Number Appearing: 1 (1)
Alignment: Chaotic [Neutral Evil]
Movement: 90' (30') [9"]
   Swim: 180' (60') [18"]
Armor Class: 6 [13]
Hit Dice: 8d8+8* (44 hp)
   Large: 8d10+8* (52 hp)
THAC0: 9 (+10)
Attacks: 2 claws or weapon + Breath Weapon
Damage: 1d4+3 x2 or 1d8+3, 
Special: Breath weapon (fetid gas), dark vision
Save: Monster 8
Morale: 10 (NA)
Treasure Hoard Class: None 
XP: 1,200 (OSE) 1,240 (LL)

Str: 18 (+3) Dex: 13 (+1) Con: 15 (+1) Int: 10 (0) Wis: 10 (0) Cha: 4 (-2)

The nuckelavee is a monster in the truest sense of the word. It appears to be a large horse with a human rider, but closer inspection reveals the true horror of the creature.  The "rider" and "horse" are the same creature.  The "human" part has a huge grinning mouth with arms that are so long that its claws drag the ground.  The "horse" part has legs that end in both fins and hooves, giving it the ability to move about on land and the sea. The "horse" head has one huge eye in the middle of its forehead.  The entire creature is skinless and the muscles and sinew are visible. The creature is covered in black blood.

The nuckelavee hates all life and will attack anything in its path.  It prefers to stay in the salt-water sea, freshwater is treated like acid to it (1d4 hp of damage per vial), so it will not come ashore when it is raining.  It hates the smell of burning seaweed and will come ashore to put out any fires burning seaweed and kill whoever is doing the burning.

Nuckelavee will attack with their claws most times. They are capable of wielding weapons and will choose a club or spear, but they prefer to use their own claws. They are strong (Strength 18) but only average intelligence (10).  The worst attack of the nuckelavee is their fetid breath.  From their horse head, they can breathe out a fetid poisonous gas that affects all in a 60' long, 30' wide (5' base) cone. Victims must save vs. Poison.  Those at or under 7 HD must save or take 4d8 hp damage (save for half), those over 7 HD save or take 2d8 hp of damage (save for none).  Anyone failing the save will incapacitate for 2d8 rounds and unable to move or attack. 

Nuckelavee prefer the flesh of warm-blooded creatures. It ignores merrows and selkies, though they can usually out-swim the nuckelavee in the sea and outrun them on the land.  

Water Horses

The nuckelavee would be a natural enemy to the kelpie and likewise, save for the fact that nuckelavees can not enter fresh water and kelpies rare venture out into the sea. There seems to be a relationship between the nuckelavee and the each-uisge.  The nuckelavee is also related, somewhat distantly, to the nøkk, though both creatures refuse to acknowledge this.  The best way to offend a nøkk is to ask if it is a nuckelavee.  Kelpies, each-uisge, nuckelavees, and nøkks are all either descended from a common creature or have all adapted similar forms as a means of capturing prey.  

--

Returning today are the Ability scores. I played around with them a bit more and have been getting some feedback so I wanted to pull them back out.  I think I am going to keep them in the stat block.

This creature is large and therefore has two lines for HD/hp.  In my games I will use the increased hp total. 

All in all I am happy with this one!

#AtoZChallenge2021: M is for Merrow

I have commented on how it is Greek mythology that brought to D&D via the Monster Manual and this month is largely a celebration of that. While Greek myths got me here, it is Norse and Celtic myths that have kept me coming back for more.

Today I had an undead monster ready to go, and it was fine, it was a good monster.  But it didn't excite me very much. It's great for my book, but not so much for a blog post trying to get excitement for that book.  So instead I am going with some more fey creatures, but this one is a little different.

John William Waterhouse - Mermaid
Merrow
Gwenhidw, Jennys
Medium Fey (Aquatic)

Frequency: Very Rare
Number Appearing: 1d4 (1d6)
Alignment: Chaotic [Chaotic Good / Chaotic Evil]
Movement: 90' (30') [9"]
 Swim: 240' (80') [24"]
Armor Class: 8 [11]
Hit Dice: 1d8+1 (6 hp)
THAC0: 18 (+1)
Attacks: 1 weapon
Damage: 1d6
Special: Magic cap
Save: Monster 1
Morale: 6 (8)
Treasure Hoard Class: Special
XP: 19 (OSE) 21 (LL)

Merrows are shy water faeries that appear off the coasts of the oceans.  They prefer to spend their time frolicking in the shallows of tide pools and having swimming contests.  All merrow seen by land dwellers will be female.  The males refuse to have anything to do with the people of the land and will not come close to it.

Similar to a mermaid, the merrow appears to be a beautiful humanoid woman's upper half. Her hair is often green, usually seafoam green, but darker sea plant colors are also common.  Her fish-like tail is of the same color.  The most notable thing about them though is their bright red cap. This is their only treasure.  

If she is spotted the merrow will immediately flee to swim back to her home under the waves. They will avoid combat whenever they can. Though some will curious enough to seek out any humans.  Merrow are curious about humans, in particular human men. Their own males are evil, brutish, and ugly.  By use of their magic caps, a merrow can change her shape to that of a human and walk on land.  As long as she posses this cap she can move freely between the sea and land.  As a sign of trust and love a merrow can give another human her cap and thus tying her to the land forever.   Land-based merrow are indistinguishable from normal humans, though they will often learn witchcraft.

Merrows are also known as Gwenhidw or "Jennys," but this could also be the name of one of their most famous members. The offspring of merrows and humans are completely human, but they feel a call of the sea and make exceptional sailors or sea witches.  A merrow still tied to the sea does not have a soul, but if they commit to the land then they are granted a new soul.  

Male Merrows: These creatures are as ugly as the women are beautiful and evil where their counterparts are good.  They never come to the surface when they can avoid it and they are generally not welcomed. Their faces are the worst combination of humanoid and fish and their whole body is covered in green fish scales.  It is said that when a Jenny comes to land and chooses a human husband her merrow father will follow her to bring her back.  The merrow will challenge the human to a game, usually, a drinking game, if the human wins the merrow returns to the sea and leaves his daughter behind.  If the merrow wins he returns to the sea with his daughter and the soul of the human.  Particularly old and evil merrow have a collection of these souls they keep in cages at the bottom of the sea as humans might keep a pet bird in a cage. 

--

This entry pulls together a lot of threads that have been rummaging around in my head for years.

Starting with the idea of Jennys and Merrows, they *might* two different creatures, but it is hard to tease apart all these myths especially when they are all so close to each other; both in content and in geography.  I like the idea of the merrows, or Jennys, as being genuinely curious about humans. Plus I liked the Jenny character from Anita. The Jenny stealing a kiss from Anita convinced me that these creatures were not evil and actually kinda liked humans.

 The idea of the Merrow men and the soul cages has been with me forever it feels like, though they were very nearly demons.  Here they are just assholes. Evil, dangerous, but still assholes. 

To say these ideas were not influenced by this would be disingenuous.

There are a lot of parallels between the merrow and pagans from the British Isles and the general belief that the Fey do not have souls.  In a game set in a magical Medieval Europe then a Jenny would need to be baptized before she would get a soul. Then of course she is no longer a merrow.   There are likely some unpleasant parallels here involving the patriarchy, salvation, goodness vs. freedom, choice, and more.  And it is all completely intentional.   Remember I am usually on the side of the pagans and freedom here.    I would rule that a Jenny deciding to stay on land with a witch would not need to give up her power or autonomy.  That's because witches understand this.

#AtoZChallenge2021: L is for Lilith

Lilith by Isra Llona
Lilith by Isra Llona
Last verse, same as the first.

This one should not be a surprise really. I have done Lilith many times before in my April A to Z. She was in my A to Z of Demons (2013),  A to Z of Witches (2014), and my A to Z of Vampires (2015).  So naturally, I want to bring her back for my A to Z of Monsters.

Lilith is fantastic. I am a sucker for any story she is in, and if she shows up on a TV show, even better.

In my A to Z of Demons (2013) I talked about how she is the mother of the Lilim Demons and what they all are.  In many, many ways she is not just the mother of demons, she is the mother of Basic Bestiary II: Demons & Devils.  It was because of the Lilim that I wanted my own demon monster book.

While the Lilim have appeared in other books of mine, namely Eldritch Witchery (with Lilith on the cover), The Warlock, and The Daughters of Darkness, I have been tinkering with them for much longer than that.  

In 2014 I talked about her relationship with witches and then expanded on that in Daughters of Darkness.  Here I listed her as "Chaotic Evil."  In Eldritch Witchery she is just "Evil" and in The Warlock she is "Chaotic."  This is all well and good, but it doesn't really fit with her does it?  Lilith certainly has a lot of chaotic attributes, but I see her more as Neutral Evil.  She may not have started out as Evil, but as they say, sometimes you play the hand dealt to you.  I am still going back and forth on NE or CE at the moment.

Lilith by John Collier
Lilith
aka Mother of Demons, Mother of Monsters, the First Woman, Queen of Night
Medium Fiend (Lilim)

Frequency: Unique
Number Appearing: 1
Alignment: Chaotic [Neutral Evil]
Movement: 90' (30') [9"]
 Fly: 180' (60') [18"]
Armor Class: 6 [13]
Hit Dice: 19d8+76***** (162 hp)
THAC0: 7 (+12)
Attacks: special (see below)
Damage: See below
Special: See below
Save: Witch 19
Morale: 12 (-)
Treasure Hoard Class: Special
XP: 7,750 (OSE) 8,000 (LL)

Lilith was the first human woman. She rebelled against the gods that created her and now controls armies of demons.  The gods won't work against her or strike her down because she knows all their True Names. This makes her the most dangerous creature in the universe. Long and ancient pacts between Lilith, demons, devils and the gods keep an uneasy balance of power.  If Lilith were to truly seek out the power just within her grasp, the gods themselves would know fear.

Lilith is also the mother of monsters.  She is the mother of demons, having spawned so many, but she is also the mother of vampires and many say, witches. She rejects these titles and her many offspring.  The only ones she is even remotely interested in are the Lilim, the so-called Daughters of Lilith. 

Queen Lilith never openly attacks.   She considers combat beneath Her and will not partake in it.  Her arena is intrigue, guile, and deception.  Why fight when a cup laced with poison or a dagger in the night is much quicker.  If forced into combat she can summon pretty much any demon she likes except for the Baalor and Baalroch demons.  If it comes down to it, Lilith can cast spells as 20th level Witch of the Demonic Tradition, though she has access to every witch spell known.

As the mother of all Lilim, she shares their powers and weaknesses.

Damage types: Acid (Full), Cold (Half), Electricity/Lightning (None),  Fire, magical (Half), Fire, non-magical (None), Gas, poisonous (None), Iron Weapon (Full),  Magic / Arcane Blast (Full), Poison (None), Silvered Weapon (Half).  

Powers (at will): Charm person or Charm monster, Darkvision, ESP, Hold Person, Immune to fear, Night Vision, Shapeshift (human, demonic, spirit), Suggestion, Telepathy, and Teleport.

Three times a day she can cast fireball, lightning bolt, and wall of fire. One a week she can grant a wish. She can see perfectly in darkness of any kind. Lilith can summon 1d4+4 lilitu demons with a 100% chance. 

She always appears as a young, very attractive woman.  Most often with long flaming red hair.  It is claimed her true form is that of an ancient hag with long, but sparse wild black hair, talons, fangs, and the wings and the feet of a predatory bird.  Either or neither could be her true form. She can shapeshift to any form she likes at will. Her telepathy allows her to assume a form the viewer most desires.

Lilith has no true friends because most fear her.  She is known to ally herself with the Goddess Ereshkigal since both have similar portfolios and areas of concern.  Some even claim that Lilith spent some time as Ereshkigal's handmaiden.  Others claim she served Astártē or Ishtar. She was once the chief consort of Hell, but even the Baalseraph fear her.

--

OK! My first major demon.  REALLY gets me into the mood to work more on the demon book.  But I still have the BB1 to finish first.  Plus doing this entry makes me realize how much more groundwork needs to be done on the demons and the regular monsters still. 

Her AKA line includes her titles, whether she likes them or not.

In the Hit Dice line she has 5 stars, which means she has five special abilities that contribute to her combat power and thus raise her XP value.  I am not sure if she is 5 or not.  Once I get done with all my monsters I will survey them and edit them appropriately. 

There are details here, such as her Lilim powers, that will be offloaded from her entry and put into the Lilim entry proper.  I just needed it here for now.

#AtoZChallenge2021: K is for Kelpie

Another "revised" monster today.  This one though is a revision of a monster that appeared back in the AD&D Fiend Folio from 1981.   Now I loved the Fiend Folio. While the Monster Manual was the first D&D book I ever looked at, the Fiend Folio was the first hardcover monster book I ever bought.  I would use it with my Basic and Expert Sets (Moldvay/Cook) and that would be my game.

One creature though I more or less ignored until I began reading Celtic myths was the Kelpie.

Now in the Fiend Folio, the monster Kelpie is a plant-like creature that is only superficially related to the Scottish Kelpie.  In fact, the creature in the FF has more to do with kelp (as in seaweed) than a kelpie.  So I figure I would update the creature a bit.

The Kelpie by Thomas Millie Dow, 1895
Kelpie
aka Water Horse
Medium Fey (Aquatic, Monstrous)

Frequency: Very Rare
Number Appearing: 1 (1d4)
Alignment: Chaotic [Chaotic Evil]
Movement: 90' (30') [9"]
   Swim: 120' (40') [12"]
Armor Class: 3 [16]
Hit Dice: 6d8+6* (33 hp)
THAC0: 12 (+7)
Attacks: grab
Damage: NA
Special: Charm, Shapeshift, Water breathing
Save: Monster 6
Morale: 8 (10)
Treasure Hoard Class: XIX (D) 
XP: 650 (OSE) 680 (LL)

The kelpie, also known as a water horse, is a shape-shifting creature of the fey that lures men to their watery lairs to their deaths.  The kelpie can appear as a beautiful woman, a handsome lad, a magnificent horse, or in its true form, a skinless, blood and slime-coated monster that combines the features of both humanoid and horse.   They live in dark and dangerous rivers and fast-moving streams.

The kelpie can only attack with its charming song which attacks like a powerful Charm Person spell. The kelpie will charm the person to approach her, in either her nymph or horse form. Once she gets her victim into the water she wraps herself around them with her strong limbs and drags them to the bottom of her lair where they drown. Victims are allowed a save vs. Spells at a -2 due to the power of the kelpie's song.  Once in the "arms" of the kelpie, the victim will need to make a simple Strength check (roll a d20 to roll under their strength score). They may attempt this in the first round they are underwater. They may recheck each round at a cumulative +2 penalty (added to their roll) each round hereafter. So +2 in round two, +4 in round three.  Once the penalty is greater than the victim's strength they drown.  

A kelpie in humanoid or horse form can move about the land but are recognizable by a few signs. In humanoid form, their hair always seems wet and they will wear a silver chain around their neck. In equine form, their hooves will appear to be backward from that of normal horses. They must return to their watery lair each new moon.  While in their humanoid or equine shape they may be "turned" by a cleric.  This turning treats them as a 6 HD creature, but they are not undead.  On a successful turning check, the Kelpie will revert back to their normal form and must get to her watery lair. All charm effects she has cast at that point end.

The Kelpie appears to be related to the nøkk of colder more northern waters.  They share a certain number of similarities, but the nøkk is not evil. 

Each-uisge. This creature is related to the kelpie and is if anything more monstrous and evil. Where the kelpie lives in rivers and streams, the each-uisge lives in lakes (lochs).  While it is unknown what the kelpie does with the humans she kills, the each-uisge has been known to eat its prey.

--

Updates.  

In the description line, the kelpie gets both an Aquatic and a Monstrous descriptor.

Since the Kelpie has better than average strength (14 in this case) I updated my THAC0 calculations to support Strength bonuses. This will not change most of my monsters since most have average strength.  But it will change others and give monsters in this book an edge over their counterparts in other books.   Of course, the Kelpie doesn't cause HP damage so her strength is not a factor in that.   

This is also one of the first "Variations" I have posted that don't require a full second set of stats, like the Faun and Greater Faun from last Wednesday.  The each-uisge is essentially the same creature, stats-wise, just from a different location and temperament.

Contrast this with the nøkk which is a similar creature but of a completely different temperament and nature.  While I could have used the same stats (and they are similar) they are different enough to make them a completely separate entry.  This means I should do a Nuckelavee too.

#AtoZChallenge2021: J is for Jack O'Lantern

Here is an old favorite of mine that I just never got right.  I had featured the Jack O'Lantern on three different occasions in three different witch books and each time there were differences.  But none of them felt 100% right to me.  This one is better, but I am not sure I got the nature I want the creature to have exactly right.

Jack O'Lantern

Jack O'Lantern
Medium Plant (Fire)

Frequency: Rare
Number Appearing: 0 (1d4)
Alignment: Neutral [Unaligned]
Movement: 90' (30') [9"]
Armor Class: 5 [14]
Hit Dice: 3d8+3* (17 hp)
THAC0: 16 (+3)
Attacks: 2 tendril whips or special
Damage: 1d6 x2 or special
Special: Breath weapon (fire)
Save: Monster 3
Morale: 12 (12)
Treasure Hoard Class: None
XP: 75 (OSE) 100 (LL)

This creature is a roughly humanoid-shaped tangle of vines and leaves with a large pumpkin for its head. The pumpkinhead bears a leering face that appears to have been carved there and glows from within with eldritch fire.

A jack-o-lantern is a plant creature brought to life by a combination of eldritch magics. It is said that druids, the fey or a witch knows the ritual to summon these guardians. The nature of the face generally reflects the animating spirit. They are considered to be plant creatures.

The Jack O’Lantern will attack with its whipping tendrils, usually two attacks per round but a rare (5% chance) one will have three. Once per day the jack o’lantern can “Breathe” fire out of carvings in its pumpkin head. A saving throw vs. Breath Weapon is required or take 3d6 fire damage (save for half).

Summoning a jack o’ lantern requires a large patch of pumpkins. Up to four (1d4) will be summoned with a single ritual. The jack o’lanterns will never wander more than 500’ away from their pumpkin patch and will attack any creature not present at the time of its summoning.

--

Well, it is certainly better than what I had before.  

This creature introduces an idea borrowed from D&D 4th and 5th Editions, and that is the Unaligned alignment.  They are neutral for the terms of the D&D Basic and OSR games, but beyond that they are unaligned. I will not use it as much as later editions of the game, but it does have its place and uses for me.

Happy Anniversary WotC D&D

Yesterday, April 10, was the 24th Anniversary of Wizards of the Coast purchasing TSR and of course, D&D.

Wizards of the Coast D&D

Wizards of the Coast bought the failing TSR for $25 Million.  Today Wizards of the Coast is worth nearly $1 Billion

This means that Wizards of the Coast has been publishing D&D longer than TSR.

TSR D&D 1974 to 1997, 23 years 
WotC D&D 1997 to 2021 (so far), 24 years.

2024, just 3 more years, D&D will celebrate its 50th Anniversary.   IF I was WotC and looking to a new Edition that would either be when I announce it or release it. 

I am not about to speculate what will be in D&D 6 any more than I am willing to speculate when there will be a D&D 6.  I am sure we will see something more akin to D&D 5 though than the radical departures that 3 was from 2, 4 from 3, and 5 from 4. 

No idea if I will upgrade or not.  I have plenty of books and games to keep me happy till I die, to be honest.  But in any case, happy 24th birthday WotC D&D.
