In 2003, Xavier attacked three Nymphs, and later killed their Satyr to make the reveal the location of the Eternal Spring. However, the nymphs fled. Xavier followed them to San Francisco. Meanwhile, his younger brother, Tull, practiced mastering the Satyr's flute, hoping that he could manipulate the other nymphs into thinking that he was their new Satyr to make them reveal it. Xavier killed one of them to threaten the other two before Piper and Paige arrived. Piper attempted to blow him up, but only managed to blow up his arm.
