Kaiburr crystal

The Kaiburr crystal was an ancient Force relic, initially located on the planet Circarpous V, locally known as Mimban. When in its natural location in the Temple of Pomojema on Mimban, the crystal increased a Force-sensitive's power one thousand times over. Among its magnification of abilities were the ability to heal, to further augment a Force-user's connection to the Force, to project Force lightning by those typically unable, and to empower and energize a tired being close in proximity to the crystal. If cut properly, the Kaiburr crystal also worked as a lightsaber crystal.

The Kaiburr crystal was initially used by priests to heal the sick in the Temple of Pomojema. However, for reasons unknown, the area was abandoned, and the crystal became a legend in the eyes of the local Mimbanites. The crystal would go on as a legend until around 2 ABY, when an elder woman named Halla purchased from one of the Mimbanites a shard of the crystal, as well as a map which led to Pomojema's temple. The woman enlisted the help of Luke Skywalker and Leia Organa, on Mimban due to a crash-landing, and helped the two escape from prison. Unknown to the three of them, this caught the attention of the Dark Lord of the Sith Darth Vader; unaware, she and her allies went on an expedition to acquire the ancient relic.

They eventually reached the temple and found the crystal; however, Vader had beaten them there. Confronting Skywalker and Organa, Vader engaged in a duel with both of them, eventually defeating Organa and driving Skywalker to the ground before losing his right arm to Skywalker's lightsaber and eventually losing the battle despite the power given to him by the crystal. Halla handed Skywalker the Kaiburr crystal, and, along with his inherent Force sensitivity, Luke used its legendary focusing powers to heal both himself and Organa, as the two were left critically injured after their duels. However, unbeknownst to any members of the party, the crystal lost its power as it left the proximity of the temple and was completely powerless once off-planet. The shard, which began the adventure on Mimban, would stay in Vader's possession until he gifted it to his apprentice, the Dark Lady Lumiya. Luke Skywalker later found use for the crystal off-planet, as a teaching tool when he started his Jedi Praxeum and as a lightsaber focusing crystal.
