This is one of the Mockven from Sarah Zettle's "Under Camelot's Banner". This creatures are related to Lynet and her siblilings. Thier brother Colan made a deal with them that he would give them a life if they helped him keep Lynet from reaching Camelot. I drew this as an illistration for a scene when Colan breaks Lynets mirror and she makes herself become a ghost and push Colan and herself off a cliff into the sea were the Mockven are waiting. She is saved by Squire Garth but, her bother is draged down into the sea by the mockven.
