Character Creation Challenge: BX RPG

I am posting this at the end of the month instead of the first (new month, new character) since April will be full of monsters.  But in a way, today's character is a monster in his own right.

Last month I posted the stats for Twill Topknot and before that Sarana, the first main NPCs of my War of the Witch Queens campaign.   While I have plenty more NPCs to figure out and stat up, there is one that I do need to do and figure out how he did it.  That NPC is Kelek the Cruel.

I have talked about good (evil) old Kelek in the past and I think stating him out is a good idea. He has his origins in Basic/Expert D&D, Quest for the Heartstone and The Shady Dragon Inn, so Basic-era is the obvious choice.  More so since he is my Big Bad for War of the Witch Queens.

One of the things I want to do with this is pick and choose from various RPG/OSR systems.  I did Old School Essentials with Twill.  While that doesn't mean I can't reuse it, but I would like to see what is out there. I also need to figure out what sort of "magic-user" old Kelek is since I also have that choice.

Much like what I have done with Skylla (with whom he has a history with) I took her Magic-user and tried her out as a witch in various OSR style games. If she is a witch, then what is Kelek?  

He is a type of wizard to be sure.  He learned his magic, so a warlock or a sorcerer (as defined by D&D 3 to 5) is fun, but not really who he is. I need some class that also has the ability to cast gates, maybe even a way to summon a minor demon or two. But not someone interested in controlling undead. Most importantly I need someone that would be able to kill a Witch Queen.  

We know from Kelek's history that he wants some form of immortality or mastery over life and death.  To me that says Necromancer.  But I am kinda bored with necromancers.  I mean I have done necromancers so many times.  BUT this group has never gone up against one of my necromancers before.  Eric over at Swords & Stitchery also talks about Kelek and even has him becoming a lich. Eric usually has very good ideas, so I am inclined to take this as a vote towards Necromancer. 

So if it is a necromancer, then which one?

The Basic Fantasy one is nice, but not really powerful enough for what I need.  The necromancer from Adventures Dark & Deep is good. Has a lot of potential but still not exactly what I want. Astonishing Swordsmen & Sorcerers of Hyperborea also has a great necromancer, but the spell list is not 100% where I want it. Magical Theorems & Dark Pacts are getting much closer, as is Gavin's Theorems and Thaumaturgy. The one that feels the closest is the one from the BX RPG.

I reviewed the BX RPG a while back and have been wanting to do something more with it. 

If he is my big bad for War of the Witch Queens then I am going to take advantage of BX RPGs 1-20 level spread and make him 15th level.

*The spells from scrolls are Necromancer spells from Theorems and Thaumaturgy. I am likely to give him other necromancer scrolls from the other necromancers out there. 

I also say mostly human since I consider Kelek to have a bit of orc in his line somewhere.  This explains his high strength and constitution, his low charisma, his pointed ears, oddly shaped head in some depictions of him.  He can also speak orc and hangs out with Zarak all the time. 

Kelek also has a large warg he rides like a horse.  In typical D&D cartoon fashion, his name is just Warg.

Yeah, I have a lot of plans for this guy. 

Now I need to figure out how he killed the Queen of Witches to get us all in the current problems we are in.
