Why this word is great
DEMONOMY — [Noun] The dominion or rule of demons; devilry. Formed within English by compounding, from the combining form *demono-* (relating to demons) and *-nomy* (denoting a system of laws or governance, from Greek *-nomia*). Unlike *diablerie* (which winks with carnival mischief) or *demonomancy* (which traffics in occult consultation), demonomy is the cold machinery of possession, the silent coup of hell. It is the whisper of unseen hierarchies in the walls of an abandoned asylum, the meticulous cruelty of a curse that unfolds by precise, inescapable rules, the way a nightmare lingers in daylight—proof that malevolence, given time, becomes administration.
