Irin (The Watchers)

The irin, called the Watchers, once dwelt with the gods until they were exiled to the astral plane because they wanted to learn every secret of heaven. Since then their lot has been to observe everything that happens across the many worlds of the material plane and learn it all. Summoned, an irin answers one question in its field or grants a wish, yet the irin have vowed never again to interfere with gods or mortals. The Divine Magic spell Greater Invocation can call one. Each named irin is level 24 with Will 24.

Every spirit entity dwells on a spirit plane and must put on a physical body whenever it is called into the prime material plane.
