Catha

Exandria has two known moons that orbit the planet. Catha, the larger and closer of the moons, is the herald of night travel and shines a bright white when visible in the sky. Catha is considered to be intrinsically tied to Sehanine, the Moonweaver and is regarded by some as a creation of the Moon Weaver to watch over the just and hide those who require obfuscation.
It takes between 30 to 40 days to orbit Exandria, during which it waxes and wanes; this is the commonly referred to as the lunar cycle. The brightness of Catha is constant and its cycles are predictable, unlike Ruidus.
