Captain

The Captain was the commander of the Pirate Vessel that Cuberos and Aska served on. She supposedly rescued Aska from slavery to another Pirate crew. For some reason, Aska tried to kill her when Aska was power crazed, presumably when the Sins laughed at her being rescued from a town siege (it's more like the Captain killed her folks and took her in).

She was originally going to have a name, but Pip decided against the name as it sounded to "ethnic" (he needed to stress the point that Sins does not take place on Earth).
