The ailanthus tree is a special tree that is found as a part of the In Pyre Need quest to help rescue the Phoenix. The "Harvest-twigs" option on this tree gives Ailanthus twigs, and left-click "Fletch" on the twigs turns it into Ailanthus weaving ribbon which is one of five weaving ribbons to be used on the pyre to kill the Phoenix and have it reborn in the Ritual of Rebirth.

- The word Ailanthus derives from the word ailanto which means "tree of the gods" or "tree of heaven."
