The Moons
Two moons rise above the world - the cobalt-blue and misty Diurnus, small and bright, and the yellow-white Regius, larger and pale and the real source of light once the sun drops. The moons rarely match in phase - perhaps once a quarter - with Diurnus changing far more slowly than the more traditional lunar month of Regius.
The moons are laced with significance by clerics and wizards and sorcerers and druids, but for every statement of their purpose, there’s a contrary one from another group. Perhaps they’re all those ideas, perhaps they’re none - but there are two beliefs that cross every culture, every profession.
Regius, it’s said, is the Lord of Light’s moon, while Diurnus belongs to the Lady. From there, they’re said to watch the world, that everywhere the light touches is, in some way, touched by them. Who can say if it’s true? That said, the lair of the Beast and its minions always is described as below ground, where the light cannot reach - where plotting can occur without being seen.
