The Throne of Flies is the palace and stronghold of the archdaemon Apollyon on the Outer Plane of Abaddon.
The Origins of the Throne[]
Apollyon's seat of power is a gigantic monolith built from the bones of an impossibly massive corpse. Adorned with its eons-old innards, it is as hideous as it is immense. The identity of the body is one of the many dark mysteries of Abaddon, alternately claimed to be a dead god of healing, a rival patron of pestilence, or a protean lord of leviathan proportions dragged from the depths of the Maelstrom.[1]
