Captain Shard

A seemingly human pirate captain who has a vast hatred for other pirates. Captain Shard, as she's called, commands elemental powers of the sea from a being known as The Fathomless. She uses her warlock magic to intimidate and extort those around her, especially so with her Tentacle of the Deeps ability.

Those close to her will know that she was once a woman who dreamed of freedom who was taken prisoner by pirates. After drowning when the ship was attacked, it was The Fathomless that made a deal with her and brought her back. Now she takes revenge on anyone who's ever wronged her, taking whatever she sees as rightfully hers (and it usually isn't).
