Charon, or The Ferryman
A ferryman that navigates the rivers of the Otherworld which flow into all realms. He is responsible for trafficking souls to their Final Rest when they are incapable of making the transition on their own.
Most of his time is spent gathering the souls of Lost Ones from the Ethereal Mist, but will also gather the souls of celestials and fiends that require transit back to their home Realms.
He is a neutral entity and never takes any moral side.
