Leuanien Teia wields du, the energy of waters, and is descended of the First Seawoman, Leu. Her mother, a proud Captain, went missing searching the western sea for the Lost Onatae when Teia was a child. Since then, she has lived in the palace and grown up alongside the Araeboril. Because of her status, she has little right to decide who she will become, let alone what she can think. She struggles with her station, with her fate, as her feelings for the Araebroil are much more than sisterly.
