Healing Crystals of Fire
these firey gemstones were among the greatest treasures of the Jedi Knights. Maintained under tight security in the Jedi Temple on Coruscant, they were used heal serious wounds. Inside each gemstone was an eternal flame. Xanatos attempted to steal these stones, along with a cache of vertex crystals, several years after he left the Jedi Order. He attempted to cover up his plans by also attempting to kill Yoda and destroy the Jedi Temple on Coruscant.
