Gestalt
Gestalts are an Undead assemblage of various non-human corpses. Less common than Frays, reports of gestalts are few, possibly because their creation is doubly difficult. If a Caster desires a familiar with certain abilities, they may construct one from the corpses of animals with the necessary attributes. Technically difficult, but possible for a skilled anatomist. Most challenging, however, is for the Caster to unite the fleshy components, fusing tendons, sinews, etc., suitably enough so as to prevent the newly risen composition from falling apart or tearing itself to pieces. The failures would seem to account for some number of the Undead Abominations.
Where was I? Yeah, right, stookin' critters! So, while the ol' fella jabbered on, "Go forth and find me five cursed wolf pelts..." and blah black blah, this winged-cat...thing just sat perched on 'is shoulder, happy as you like, bits fallin' off'a'it like soggin' seaweed! I dun' think it were, y'know...cooked right.
