Character: Magnus Ulslime, the Chaotic. Death Pact Warlock (BECMI Special)

Last week I talked about the adventure Quagmire for the Expert set.  Earlier I talked about the adventure Death's Ride for the Companion set.  What do these both have in common?  They were the genesis points of a reoccurring bad guy in my games, Magnus Ulslime, the Chaotic.

Magnus, as he was most often known in my games, is not just an awesome reoccurring bad guy, he was my testbed for all sorts of evil, death-priest, warlock style characters.

Anytime a new version of D&D would come around I would roll up a new Johan Werper as the son of the previous one, either as a LG Cleric or Paladin.  I'd attempt to make a version of Larina.  And I would make a version of Magnus.  But unlike Johan, who is a different character each time but always a LG holy warrior, or Larina who was a reincarnation of her previous version and always a witch, Magnus was always something different.  I would always go with the class that would give me the best evil traits.  In Basic he was a evil Cleric. In AD&D1 a Death Master, in 2nd Ed he started out as a Druid and then became a Necromancer.  When I switch over to 100% Ravenloft in my college years the cover of Ship of Horror and the evil necromancer Meredoth also had a huge influence on me.  As it turns out Meredoth would be revealed as an expatriate of the Mystaran country of Alphatia.
In 3rd Ed...well there were some many choices that I eventually made 6 different versions.  You can see some of that in my Buffy adventures The Dark Druid and The Dead of Night.  In 4e I used him as a test of the Death Pact Warlock that never saw the light of day under 4e.  It did, however, affect the writing I did for my warlock books.

Magnus Ulslime became my poster boy for warlocks soon after I got a copy of 4e.
I tried him out in several different ways mixing in bits of cleric, wizard, and especially necromancer.
In my Strange Brew: Warlock book for Pathfinder I introduce both Cthonic and Death Pact warlocks.  I expand on those ideas from a different point of view in my more recent book, The Warlock for Old-School Essentials.  In both cases, I made Magnus a Death Pact warlock.  It was a much better representation of how I saw the character.  He made a trade to Death for more power in the mortal world.

Magnus for BECMI
If I rerun Death's Ride again for any version of the game I'd like to replace Ulslime the Cleric with Magnus Ulslime the Warlock.  For 3rd to 5th Edition of D&D this is not a big deal.  But BECMI does not have a warlock.

No. But Old-School Essentials and Swords & Wizardry do.

My warlock for Old-School Essentials is a B/X style warlock with Death Pacts.  But it only goes to 14th level.  My warlock for Swords & Wizardry goes to 20th level (the level I want Magnus at) but it doesn't have Death pacts.  No problem. I designed the books to work together like this.  By combining them I can get the exact warlock I want.  If I need more death or necromancy themed spells
