The storyline in
Jedi Knight follows
Kyle Katarn, who first appeared in
Dark Forces. Katarn's father had been murdered by a
Dark Jedi over the location of "The Valley of the Jedi" and the game follows Katarn's attempts to find the Valley and confront his father's killers.
The game is set one year after the events of
Return of the Jedi. The player controls
Kyle Katarn, who made his first appearance as a
mercenary in
Dark Forces. On Nar Shaddaa, Katarn meets with an
information broker droid named
8t88 who tells Katarn that his father, Morgan Katarn, was killed by a
Dark Jedi named
Jerec, who also intends to rebuild the
Empire under his rule. After a lengthy firefight, Kyle retrieves a disk from 8t88 that can only be read by WeeGee, the Katarn's family droid. The disk's message, coupled with WeeGee giving Kyle a lightsaber, compel Kyle to undertake a journey to confront his father's murderers and discover his own latent Force abilities. While on this journey, Kyle learns that seven Dark Jedi are intent on finding the "Valley of the Jedi", a focal point for the Force and sacred ground for the Jedi. Guided by Jedi Master Qu Rahn, who was recently cut down by Jerec, but who lived on as a force spirit, Kyle must defeat Jerec's Seven Dark Jedi in order to stop Jerec from gaining infinite power.
Katarn retrieves the Valley's location and travels with
Rebel Alliance agent and close friend
Jan Ors to
Ruusan, the planet on which the Valley is located. Jerec captures Ors and offers Katarn the choice to execute her or die. The decision Katarn makes here depends on the player's actions within the game up to this point. If Katarn has remained true to the light path he spares Ors, but if he has fallen to the dark side he kills her. With both paths, Katarn has a final confrontation with Jerec in the Valley of the Jedi's core. If the player chose the light side, the game concludes with Katarn being reunited with Ors and carving a monument to Rahn and his dead father; if the player chose the dark path, the game ends with Katarn becoming the new Emperor.
