Kyle Katarn was born to a farming family on the Sullustan moon of Sulon. At age eighteen he enrolled in the Imperial Military Academy on Carida. But, as he trained to become an Imperial Officer, he never realized how envolved his father, Morgan, was to the Rebel Alliance. For nearly four years, Morgan Katarn had worked against the Imperial's. He had helped refugees to Ruusan, where he located the Valley of the Jedi, lost for a thousand years.  Discovering that the Valley contained powerful Jedi spirits, Morgan kept it a secret. Also in the valley was a hiding Jedi named Qu Rahn, who advised him to carve the coordinates on the roof of his home. Morgan also took Rahn's saber as a gift for Kyle. However, several months later, the Dark Jedi Jerec lead a raid on Sulon's Rebel cell, decapitating Morgan with a vibroknife. Meanwhile, Kyle neutralized an enemy held asteroid, but sparing a beautiful Rebel woman named Jan Ors. For this, he received the Medal of Valor from Jerec at Carida's graduation ceremony. This otherwise happy day was spoiled by the news that his father had died, the report saying he was killed by Rebels. After graduation, Kyle was sent to his first posting. En route, Jan Ors presented him with proof that Imperials, not Rebels, had killed his father. He disposed of his medal and joined the Rebel Alliance. Mon Mothma allowed Kyle to go after the plans for the Death Star. He took a battered old ship, the Moldy Crow and traveled to the stronghold on Danuta. He defeated hordes of Stormtroopers and retreived information that, when combined with information from the other spies, provided a full technical readout of the battle station. In light of his success, Mon Mothma gave him another mission, he was sent to stop the Dark Trooper. He stole on board Admiral Mohc's ship and freed Crix Madine, leading to a final stand off with Boba Fett. He destroyed the Dark Trooper Equipment and returned to tell the good news. Over the next few years, Kyle continued doing work for the Alliance. One year after the Battle of Endor, Kyle discovered that it was Jerec who had killed his father. He fought many of Jerec's minions in his quest for revenge. He was guided by the spirir of Qu Rahn, who led him back to Sulon, where Kyle discovered Rahn's lightsaber. The map to the Valley, however was gone, stolen by Jerec. Katarn got a copy, and the race was on. Jerec sent his six underlings- Yun, Gorc, Pic, Maw, Sariss, and Boc- to slow the Rebel down. However, they proved no match. Kyle cut down all of them except Yun and Sariss. Out of gratitude, Yun saved Kyle from Sariss's blade, dieing in the process. During the battle, Boc damaged Kyle's saber, so he took Boc's for himself. During the fighting, Katarn started growing near to the dark side. In the final confrontation, Kyle saved himself, refusing to kill Jerec in cold blood. Instead, he defeated him in fair combat, freeing the trapped Jedi spirits. Katarn refused Luke Skywalker's offer to receive Jedi training, instead joining the military, working his way up to the rank of captain. During this time, he met another rogue force user, Mara Jade. Together, they practiced and honed there abilities. During the resurrected Emperor's campaign, Katarn was stationed on a New Republic outpost on Altyr 5. Ancient inscriptions led him to the swamps of Dromund Kaas, a Sith world. The emmense amount of residual dark side energy sucked Katarn into the dark side. Mara Jade found him and brought him back to the light. Not wanting that to happen again, he enrolled at Luke's academy. He thought he was failing and turned his back on the force, becoming a mercenary for Mon Mothma. However, this didn't last long, and he soon returned to complete his training. He became an instructor, training such great Jedi as Jaden Korr and Rosh Penin. During the Yuuzahn Vong invasion, Master Katarn fought at the Battles of Ithor, Obroa0skai, and Gyndine, helping to rid the galaxy of them.
