so atheria and ceres are doomed lovers, deities that embody the elements of light and darkness. except atheria is dead in the narrative, her soul shattered from a powerful magic she tried to control, and it caused her doom. but! she's not rly dead because as her soul shattered, over time two halves ended up forming of her soul and were born into, drum roll, SINIE AND CSILLA :D ceres is actually after sinie and csilla for their souls, ceres wishes to bring atheria back to life and make her whole once again.
now this brings us to urania! im still working on refining her origins, but she's the Squad Mom for sinie, csilla, and squad. she is there when sinie and csilla's powers awaken and she really takes on the role of a mentor and guardian that can protect and bestow wisdom upon the young warriors. she definitely knows more than what she lets on, and she is definitely hiding things, but she has all good intentions.
