Jiya Chai

Chai is a lively soul (she died long ago) who lives in the 9th layer of Heaven with the Creator of all creatures, the Great Spirit
Enduri. Even though in an everlasting rest, Chai loves to help other spirits and people still living Under Heaven.

      She also enjoys playing music very much, and will sometimes descend to Earth in order to play music with people.

     Naughty sometimes, but her naughtiness brings no one any
harm and makes Heaven a more lively place. Impatient also, especially when talking to others, however, not
because she wants to do her own things but because she is too
eager to know everything about what others are telling her. 

     Chai is also a fighter against evil spirits, who try continuously to harm people's souls or thwart the Great Spirit Enduri's plans. Chai is the spiritual protector of many people, and she protects
Sjen together with Tienrren (one of the other 3 highest spirits
along with Enduri and Sinnraenn).
