Powers That Be
When the Dark Realm was decreed in order to shape the balance of the created worlds, a request was sent out to the Hierarchy, asking for one from the higher levels to volunteer in the creation of the Dark Realm. That one would afterward be named Lord of the Dark Realm and he would hold sway over all he'd created—worlds and creatures alike. None came forward. Another call came, and still none answered. Finally, Kifirin, high among the Nameless Ones but still a lesser god, offered. His offer was discounted at first, as he held insufficient power. The call went out a third time, and still none were willing.
"I grant this power to you," Kifirin's parent, one of the Al'Riyu who loved his child dearly, agreed to lend much of what he held to Kifirin. "This power will return to me, once the Dark Realm is complete. What you hold will be sufficient past that."
Kifirin bowed and accepted his parent's offer. The Dark Realm was created, according to Kifirin's designs and expectations. Then, because he had no prior experience at creating the races and held little knowledge of how sentient creatures might grow and develop away from his care, Kifirin made a promise never to interfere with the Dark worlds or their decisions. Thus were sown the seeds of the Dark Realm's destruction.
