Crimson Forever
this was the name given to the unusual disease encountered by the galaxy in the year between the Battle of Hoth and the Battle of Endor. The crew of an Imperial Star Destroyer contracted the disease from an unusual crystal, and the vast ship was found adrift by Luke Skywalker and Rogue Squadron. The crew's eyes and skin had turned a blood-red color, and they had no vital signs. After locating the crystal, Luke and the pilots all succumbed to the disease. However, it was later discovered that none of the beings who contracted the Crimon Forever - named for the weird coloration of the victim's skin and eyes, and the fact that the coloration didn't fade - were simply put into a deep comatose state. Their bodily functions were slowed down to the absolute minimum, so they appeared to be lost forever. While under the Crimson Forever, victims had intense dreams. Domina Tagge later revealed that the stone which seemed to cause the disease was actually part of a pair which, when separated, produced a negative aura within the Force. Once the two stones were reunited, the Imperial crew and the members of Rogue Squadron were revived. The priests who worshipped the stones revealed that they were actually living beings. Rather than risk another outbreak of the disease, Leia Organa placed the two stones together in a Star Destroyer, and set its auto-pilot to travel at sublight speeds into the intergalactic void.
