Following a disastrous confrontation with the malevolent Krath, Jedi Knights from all over the Galaxy come together on the planet Deneba to deal with this new threat to peace and justice. Ulic Qel-Droma makes a dangerous proposal: he will infiltrate the Krath and learn the secrets of their dark-side power.
As Ulic’s own Master Arca and others protest his plan, assassin droids sent by the Krath unleash deadly weaponry, killing many brave Jedi before they can be destroyed. Among the fallen is the great Master Arca himself.
As Ulic mourns his teacher, Nomi Sunrider warns Ulic Qel-Droma that it is foolish to think he can eradicate the dark side by learning its ways. But Ulic Qel-Droma vows to succeed where others have failed: “I will do this for Master Arca... for all the Jedi Knights... and for the good of the Republic!”
Few among the great Jedi gathered on Deneba have foreseen the far greater disturbance that is about to divide the Galaxy.
On the planet Korriban, the wandering Jedi Exar Kun discovers a valley of spectacular Sith tombs. There, the spirits of the ancient Dark Lords of the Sith test their new protege.
As alchemical Guardian creatures attack him, Kun finds his light-side powers mysteriously blocked. The only way Exar Kun can defeat the monsters is to release the power of anger, which bursts through him with great force.
Now, guided by the dark spirit of Freedon Nadd, Exar Kun sets out to retrieve ancient Sith power objects on a remote jungle moon...
In search of ancient Sith magic, the Jedi Exar Kun travels to a place of mysterious, mystical power -- a power so dark, so evil, that his very link to the light side of the Force is shattered. Jedi powers can't help him here. Only the dark side of the Force can save him -- even as it consumes him!
