I thought I could probably tell a little bit of Bane's story through a stained glass art piece. See Bane was possessed by a dark being, which is actually a demon, since the people were scared and thought it was Bane being corrupt, he was banished. Right before the kick out of Osmea, the demon painfully jumped out of Bane and took off to the shadows in a odd hybrid Kirin form. Leaving Bane scarred with possession side effects and severe trust issues.
