Lamia
Lamia is an ageless being that became Aletta's Ethereal Companion at an early age when she was ten years old.
People in the physical world that are gifted in magics and the ability to traverse the ethereal plane are by nature granted an ethereal companion. They act as a kind of guide and companion for the child or person coming into their abilities and to traverse the ethereal plane as they come into it, if they do.
Lamia has existed for an incredibly long time and has seen much develop and change in the world of the physical. When he discovered Aletta and sought to join with her and be her companion, he had wrongly assumed (and believed what the ancestors dubbed her) as a seer of the pantherea. However as time went on it was learned by him and all that she was a child of the Ethereal father, a goddess.
