Her ship contains a vast treasure, and she would have her ghost pirate crew tell stories about the treasure in an attempt to lure other pirates to the ship and turn them into members of her crew. Those who are alive can not harm the ghosts, and the ghosts can only harm the living on the ghost ship. One of her ghost pirates told Ioz about the treasure, and when Ioz came to look for the treasure, Cressa told her henchman that he had chosen well as Ioz was "as handsome as he is greedy". Ren and Tula tries to save Ioz, but they were unable to do anything as they could not harm the ghosts.
