Eua and Uea are the twin daughters of A, who was rent in two during the early battles of the Gods. They have never been on good terms. Uea the Unseen prefers to remain in the background, quietly manipulating those around her and meditating on the state of the World. Eua the Seen is fierce and headstrong, with a mischievous streak. However they are still simply aspects of one God, and are never far apart.
Their predecessor, A, was a God who coveted beauty, and wished to hide it away only for himself. This obsession has been obscured but not destroyed in his daughters, who aim to carve out a private notch of World for themselves.
Unlike many Gods, unlike even her own sister, Eua takes pleasure in entering the World herself, albeit only to cause mischief and partake in Worldy delights.
