Isha is one of Erudite's two moons, specifically the one that was shattered. Like its counterpart, Isha takes the form of a large snail shell, and it is in fact the corpse of the goddess of the same name. The trail of debris of her shattered shell formed Erudite's ring known as Isha's Grace. Despite Isha being dead for thousands of years, tremendous magical energy still radiates from her body which can be channeled to perform a variety of different spells.
During the era before the Shattering, Isha was a member of the Old Pantheon. Isha's body glowed an ethereal grey like a nebula among the stars while her shell was rocky with spiral patterns evoking the movement of planets and stars.
Considered the matron deity of fairies, she was responsible for the creation of numerous titanic beasts large enough to be considered gods in their own right. She entrusted the carriers of her will to the Moth Mothers, enormous moths who were the precursors to the Unelm Fairies - the moth fairies and the first of the fairy clans. Isha was responsible for bringing life to the various insect species. She filled Erudite's forests with primordial life while her sister Ema was responsible for the creation of mortals.
