Governmental authority within the Eternum is held by a loose council, a collection of undead and necromancers who were present during the empire's founding and oversee its management. Each council member holds some level of power over smaller groups within the empire, as specialized or general as desired.

Should information ever need to be quickly transmitted down the chain of command, necromancy is often utilized. A message is sent down to necromancers via undead messengers, the most common of which being avians, who then transmit the information to undead Eternals.
