Duel of the Crystal Cave

Duel of the Crystal Cave was the first battle of the War of the Resurrected Emperor. The Reborn Sith, angry at the loss of the galaxy, devised a plan to take it back. They gathered 50 Dark Jedi and went to Kronos, a planet famous for its' resurrection crystals, and tried to steal palpatine and Darth Vaders' crystals. They fought the two Guardians (two Jedi that were assigned with protecting the cave, who could never die). They were able to steal it, but only after 49 members of the strike team had been killed.
