Xavier and Tull

This demon appeared in the Season 5 episode Nymphs Just Wanna Have Fun. Xavier is the son of Naides and the brother of Tull. They sought the help of the wood Nymphs and their Satyr to take him to the Eternal Spring, a deed that would make him immortal and indestructible. Tull killed the nymphs satyr and Xavier killed one of the nymphs, Lily in order to get what he sought. The nymphs took Xavier & Tull to the Eternal Spring. Piper vanquished Xavier and Tull drank from the Spring and became immune to their magic so a spell was cast to give him roots and turn him into a tree. The spell used to do this required objects representing the four elements: Fire - matches, Wind - a novelty fan, Water - a bottle of it and Earth - dirt. It reads thus:
 * Changing seasons changes All,
 * Life renews as Creation Calls.
 * Nothing is Immune, everything Transmutes
 * Take this Demon and give him Roots.

Xavier was portrayed by Pat Healy, Tull by Jaimz Woolvett
