Chasme
Demon of Betrayal and Sycophancy
Habitat. Planar (Abyss)Treasure. Relics
Flying forth from the Abyss, chasmes resemble horse-size flies. They incapacitate foes by producing a mind-numbing droning, then use their proboscises to drain victims of life. In the Abyss, most chasmes obsequiously serve more powerful demons and search for captives to press into demonic hordes.
