Necrocracy

Power structure ruled by the literal, preserved, or undead remnants of past leaders, utilizing macabre spiritual traditions to maintain social stagnation.

The chill of a society ruled by the dead, where the grave is the seat of power and the living are subject to the will of preserved or spectral rulers. It is the unsettling stillness of absolute control, the macabre rituals that bind the living to the will of the deceased, and the profound social stagnation that results from a government that cannot die.
