Mysteries of Enthar
Celestials are powerful outer beings representing ideas throughout reality. They are worshiped as gods of their domains. They are seen each night in the numerous stars in the sky. However, the darkness in between each star is the lack of light left by a fallen celestial.
The most recognized celestial is Xol, being of light. He is seen as the sun found in each day. The next is Zel, guardian of night. He is seen as the moon gently drifting across sky each night.
