Celise

Celise, a corrupted version of the Mákó-Laphot Qelise, meaning night, and also the god of darkness in ancient Aziphox  mythology, was the only moon of Ise and the largest moon in Ceixeús  relative to its parent planet, having more than half the mass of Ise. Many scientists considered Ise and Celise to be a binary pair, due to their similarity in mass and radius.
