Altallas is a Human (Theros) who usually wears common clothing with some leather accessories and bracers; her bright hair, pockmarked skin, and general demeanor show she's spent a lot of time on board Captain Shrapnel's ship. About 80% of the time, Altallas is a foolhardy drunkard. The other 20%, she's just foolhardy, which is most often somehow worse. She has immense, honed skill that she can use whilst drinking her heart out that enables her to dance around the ship, changing the sail direction and managing the deck at the same time. Though, she has a penchant for challenging others to duals, fistfights, or general challenges along the way.
Altallas leads on the Riddle of Lightning as the Sailing Master, a role she holds with great pride and arrogance.
