Orrery of Umdeed

The Orrery of Umdeed is an ancient orrery, a mechanical model of the Xollum-Xolrut System, used by Impendians to depict the orbits of the planets and moons around Xollum. There are many orreries with this name, as Umdeed is a god of wisdom and understanding, and in particular of astronomy.

The orrery was originally kept in the now ruined Temple of Yi'is Ud, where it provided a centerpiece to Xolhengian rituals of shadowtides and bloom.
