Werefolk

Physiology
The werespirit is a paracitic energy life form that cannot survive without a physical host. The host may be any living creature with a spinal column.

Mythology
Werefolk have their own origin myth: Long ago, when the First People were one tribe, a goddess fell in love with a human princess (the faeries claim it was a sidhe princess). When the princess was mortally wounded, the goddess descended from the spirit world and joined with the princess, merging their souls and keeping the princess alive. What the goddess didn't realize was that this was irreversable; separating from the princess would destroy her soul.

Being infused with a goddess had an unusual effect on the princess--she discovered that she could change her physical form into that of any animal. The princess lived a long and happy life. When she died, the goddess found herself unable to return to the spirit world. She began to fade, unable to exist in the physical world without a physical body. Desperate, she sought refuge in the first human she could find.
