Continued . . .
Skywalker taught his students all aspects of the Force, as he had been taught by his Masters Obi-Wan Kenobi and Yoda: levitation, visualization of battles, sensing other living creatures, calming and healing, and many other Force exercises. He also allowed them access to Vodo-Siosk Baas's Jedi Holocron.
But the evil spirit of Dark Lord of the Sith Exar Kun was trapped on Yavin Four. Kun first tempted Gantoris, but the student turned on him and was killed. Later, Kyp Durron would be seduced by Kun's promises of power. The boy helped the Dark Lord attack Luke, leaving the Jedi Master's body comatose.
Luke's spirit survived in the same neitherworld Exar Kun's shade inhabited. Luke soon found out that Kun had become adept at using the dark side of the Force to influence the living world. Over the following weeks, Kun used his powers to try to destroy Luke's body, but it was protected by Leia and the Jedi initiates.
Finally, the intiates lured Exar Kun to appear in the grand audience chamber where Luke's body lay in repose. They focused their will into a single entity of the Force, and Luke's spirit appeared to aid them, as did Vodo-Siosk Baas's spirit. Their combined powers and energies of the Jedi extinguished Kun's dark light.
Shortly thereafter, a penitent Kyp Durron returned to face his punishment for the crime he had committed while in the thrall of the dark side. Luke was forgiving; he accepted Kyp back into Jedi training, and later traveled with him to the black-hole cluster known as the Maw to help destroy the threats of Imperial Admiral Daala.
Peace was restored to the galaxy for a brief, shining moment. Luke knew that he had set out on the correct path; the Jedi he trained would be the hope of the future. But even though he had an academy to run, Luke didn't stay on Yavin Four. One of his adventures found him taking Nichos Marr and scientist Cray Mingla to check out an inoperative spaceship called the Eye of Palpatine. On the ship, Luke was surprised to discover that the essence of a Jedi woman named Callista, trapped inside the computer core, had kept the weapons systems incapacitated for thirty years.
In order to destroy the Eye, Nichos and Cray stayed behind, sacrificing themselves. Luke mourned not only their loss, but that of Callista, whose dream presence and computer conversations he had fallen in love with. To his surprise, Cray reappeared in an escape pod, but he soon discovered it was not really Cray; Callista and Cray's essences had been exchanged before the Eye blew up. Callista accompanied him to Yavin Four, where they began to plan a future together.
Okay, this is basically where our sim splits from the timeline of the novels. The rest of the bio will be completed soon, I promise! :)
