Connected to the physical world, the gurihal, is the shadow world, the hisil. In the hisil, spirits live. Most are small, urging those in the gurihal to act in accordance to their nature so that they get stronger. The greatest of the spirits are the Celestines, which are the spiritual counterparts of the great bodies that are in space. Mother Luna is a Celestine.
