Filling out the story of Kaiko, the lost deergirl spirit. She appeared in a magical plane of crystal one day with no memory of who she was or why she was there.
She had a mind, some basic knowledge, and the feeling of memories, but nothing more.
But there was a deep, ineffable feeling that something of her was missing, lost. So she would search, looking for the feeling of her lost heart.
This whole character was a whole way to express my depersonalization and emotional distance issues. Slowly working out of it but its really important to me.
