Xavier and Tull were a pair of powerful demon brothers who sought revenge for the death of their father, Naides. Their goal was to find the Eternal Spring to become invincible.


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.

When Piper and Phoebe traveled to the nymphs' home through the use of Paige's spell the next morning, they found Xavier there, and Phoebe vanquished him with a potion. However, Tull was able to trick Daisy and Miranda into leading him to the Eternal Spring, thus giving him the chance to drink from the spring and becoming invincible. Realizing that they were now unable to vanquish Tull, Piper and Paige instead combined a spell to transform him into a tree—something that was also immortal.
