Mania

Ghostly apparitions with a distaste for the living, they are completely insane and think differently than most living and undead creatures. In the long run, a mania only intends to stir fear and chaos in the world of the descendants. They are susceptible to both light and holy magic, and are weak to ferrum and aurum. Ferrum and Aurum both disrupt the mania's connection to the mortal plane, and will demanifest them upon contact. They rely on invisibility and manipulation to achieve anything, and are able to control weak minded people and animals. They are also able to evoke pure force from the void, and use it to shove or trip people, they hold minor abilities in magics pertaining towards illusion and can utilize weak telepathy. They rely on their elusiveness to avoid possible death, and to permanently kill one you must use holy magic.
