Aerius was a Hive World of great importance to the Imperium.
The planet suffered a devastating plague when the Balestar, a comet appearing every two thousand years, returned.[1a] The plague was connected with the enigmatic Black Pyramid, an impenetrable Eldar structure which was built, unknown to the local human population, to restrain a Daemon Prince of Nurgle called Botchulaz.[1b]
