The blurb for Goëtia, or, the Summoning of Demons, which is the upcoming issue of Ken Writes About Stuff, mentions three demons: Bifrons, Glasya-Labolas, and Marchosias.
Unfortunately, as we (or rather, as Simon, and you, and Cat, and everyone but me) learned with the Voodoo kerfuffle, writing up a new magic system — in this case, as the name indicates, goëtia, the demon-summoning art of European magic — can run a little texty. So the KWAS issue in question wound up only having one demon in it, Buné. Now before you get all outraged, note that this time I worked very hard to provide a good general demon-statting matrix. Also, goëtia already has a great list of demons in its major sourcebook, the Lemegeton Clavicula Solomonis. But, bearing in mind what we (or rather, what Simon, and you, and Cat, and everyone but me) learned with the Mind Control kerfuffle, it’s always a good idea to honor the spirit of the blurb. Especially if it’s a blurb about spirits. Who command, you know, legions of demons.
So here, then, are the three Demons of the Blurb of Goëtia, statted up per the guidelines in the Goëtia issue of KWAS. Zim-bala-bim! As one never says in goëtia.
The Lemegeton says of Bifrons:
He is an Earle and appeareth in ye forme of a Monster at first but after a while at ye command of ye Exorcist he putteth on ye shape of a man, his office is to make one knowing in Astrology & geomitry & other arts & siences, & Teacheth ye vertues of all hearbs, precious stones & woodes, he changeth ye dead Bodyes & putteth Them into one another [anothers’] places, & lighteth candeles seemingly upon ye graves of ye dead he hath under his command 6 Legions of spirits.
As an Earl, he has Aberrance 31, Damage +5, and -2 Armor. He requires a pentacle with Might 31 or more (total Inscription roll + spend = 6+) to hold him.
He appears “in ye forme of a Monster” implying that his form is even more horrible than other demons; failing a Stability test when beholding him costs a further +1 Stability.
He teaches various abilities: Astronomy, Geology, and Mathematics (in games with that ability) for sure; likely Art, Pharmacy, Outdoorsman; possibly Occult (“vertues” means more than just healing and flavor profile); and “other arts & sciences” so at the GM’s discretion most Academic or Technical abilities, plus Mechanics. (Lots of Ashen Stars abilities, too, if you’re a space-demon weirdo.) If the GM is generous, he teaches Magic.
He changes “dead Bodyes” — not merely swapping them around (although that act likely only costs 1 Constriction, as it’s both mentioned specifically and requires a degree of player ingenuity to use well) but also reviving them as zombies, or performing other necromantic services. (Oh, I just thought of one — Bifrons makes a great crime scene cleaner. Swap out the guy you killed for some other guy who’s clearly been dead for ages.) He commands corpse-candles, which might be murony or chupas from Night’s Black Agents, or Space Eaters or Mi-Go in Trail of Cthulhu, or something else entirely.
The Lemegeton says of Glasya-Labolas:
He is a Mighty president & sheweth him selfe in ye forme of a dog with wings like a griffin; he teacheth all arts in an Instant, and is an author of Blood shed & Manslaughter, he telleth all Things past & to come, if desired, & causeth love of friends and foes; he can make a Man goe Invisible, & he hath under his rule 36 Legions of spirits.
As a President, he has Aberrance 53, Damage +8, and -4 Armor. He requires a pentacle with Might 53 or more (total Inscription roll + spend = 8+) to hold him.
He “teacheth all arts” so probably any and all Investigative abilities, definitely including Magic. (Look, if you summoned a President, you got your money’s worth. Just like now.) His zest for “Blood shed & Manslaughter” tells you he’ll be eager to kill your foes. Or your friends. He probably accelerates other people who hate your foe into attacking them first, then comes in to finish the job, all for just those 2 Constriction.
He can predict the future, and change human minds to love you (effective Credit Rating upshift, or supernatural Flirting, is up to you). This un-natural love lasts longer than just the next sunrise — until Christmas or Easter, perhaps.
Plus, he can turn you invisible, which is nice.
The Lemegeton says of Marchosias:
He is a great and mighty Marquiz appering at first in [the] forme of a wolfe; having griffins wings, and a serpents Taile, vomiting up fire out of his mouth But afterwards at ye command of ye Exorcist, he putteth on ye shape of a man, and is a strong fighter he giveth true answares to all questions, & is very faithfull to ye Exorcist in doeing his Buisness, he was of ye order of Dominations he governeth 30 Legions of spirits, he Told his chiefe Master which was Salomon, that after 1200 yeares he hadd hopes to returne to ye 7th Throne.
As a Marquis, he has Aberrance 23, Damage +3 (actually +5), and -1 Armor. He requires a pentacle with Might 23 or more (total Inscription roll + spend = 5+) to hold him.
He breathes fire, or maybe vomits lava, which is important or at least cool to know, and changes from wolf (well, winged, snake-tailed wolf) to man. He therefore likely controls werewolves, and may have a shapeshifting skin to offer if you’re using the demonic item rules.
He is “a strong fighter” so he does an extra +2 damage even as a measly Marquis. In human form, he has a Hit Threshold of 5 or even higher if he spends Aberrance on it.
He answers questions fully and completely.
He is “very faithfull” so once he signs the Book of Pacts, the Difficulties of Invocation, Evocation, and Abjuration drop by 1. This is probably because he still thinks he can get back to Heaven and resume being an angel. Of course, in 950 B.C. he thought it would only take 1,200 years, so perhaps this motive is a little outdated. Still, it offers the rare chance to use Reassurance on him (2-point spend for +1CA).
