While running from Bloth, the crew rescues an old woman named Cray who knew Ren's Father Primus and is an alchemist. She saves them, but offers anything for a sample of Dark Water to use in a potion of hers, but Ren refuses. She then uses one of her potions on Tula to force Ren to do her bidding and uses the Dark Water in a potion to make herself young again in an attempt to reclaim her youth.
