Arisen Aaru Tunic

Osiris, a man unknown to the siblings, fled Aaru not long after Ptah's departure, for he too had grand illusions of power and glory. He travelled West, following what he thought to be Gengen-Wer's trail. And while he did not find Gengen-Wer, he found plumes of feathers, fallen from the great bird. And where these feathers lay, the power of beasts was awakened. Kingdoms arose. First Elysium, built upon a rift to the underworld, where Osiris was destined to rule. And as the wind took the feathers South of here, Nothren was sure to rise.
