Agares, Angel of Despair
This is the conclusion. Agares takes little interest in the powerful figures that make their home upon the mutable surface of his world. From the ruins of Nyx the demon princes raise dark palaces and lay claim to their own small fiefdoms. There is little beyond this. The demons are drawn to Nyx because of their affinity to Agares, but few remain here long. Instead they begin their plots on Arcanearth or join the ranks of a god that appeals to them. In time their fiefdoms vanish and their palaces fade back to dust.
Bhall and her corrupted angels lay burning in this realm. It is at the edge of Bhall’s influence that most demonic activity manifests. As was never true before her fall, the demonic denizens of this realm have begun to act together. Impassioned by her presence, the fiends delight in schemes to undermine the angels still loyal to The One. Cabals have formed and even Hyborem seeks to challenge Creation.
