Night Domain

The moon, stars, and darkness always have a strange draw to them. Those who wander in darkness need a guide, a protector, or a scourge for those who would cross or defile the beauty of the night. Clerics of night deities devote themselves to a moon cloaked life of wandering and exploration in darkness. A Night Cleric (sometimes called Dusk-walkers) devote themselves to the will of a being that leads them to the unpredictable darkness of what waits. Night clerics often follow good deities like Ivandra or Sehanine as they are frequently tasked to defend those who rest in dark places, but others do the opposite following the will of dark forces to hunt those unfortunate enough to meet them. Followers of Torog or Zehir will often wield the powers of the Dusk-Walker slaying those who they find in the darkness at whim of the dark being they serve.
