Healing Crystals of Fire

During a series of robberies, the Dark Jedi Xanatos attempted to steal these precious stones. He took the stolen stones to the Temple's fusion furnace in an attempt to destroy the Temple, yet Jedi Master Qui-Gon Jinn figured out Xanatos' plans and recovered the crystals in time. Returned to their rightful place in the Temple, the crystals were lost during the Great Jedi Purge.
