Queller demons were an extraterrestrial demon species that, oddly enough, dwelled within certain meteors. They were summoned to eliminate the insane, particularly in middle ages Europe.
Powers and abilities[edit | edit source]
Queller demons were able to stick on flat surfaces such as walls and ceilings. Having slug-like bodies they usually crawled but were also capable of leaping with great agility. They had the ability to track down the insane and to spit a gooey, alkaloid substance which they used to choke their victims. Given their usual habitat, they could most likely survive in the vacuum of space unaided.
