The Mandalorians attack the Teta system. They do not want to conquer. They simply want to win battles for the glory of it. Mandalore, the leader of the Mandalorians, challenges Ulic Qel-Droma to a duel. If Ulic wins, the Mandalorians will serve him.
On Ossus, Exar Kun still pretends to be a Jedi Knight. He offers other Knights the ability to learn forgotten and forbidden Force techniques if they will become his apprentices.
Ulic defeats Mandalore, but decides not to kill him.
Kun secretly kills Odan-Urr and steals the Sith holocron he was guarding. Some of the Knights, including Crado and Oss Willum, he was recruiting agree to join him.
Ulic and the Mandalorians attack Coruscant.
On Yavin 4, Kun breaks the Sith holocron and it absorbs into his new apprentices, turning them to the Dark side via possession.
On Coruscant, Aleema betrays Ulic, ordering the Mandalorians to retreat without him. Ulic is then captured by Cay, Nomi, and Master Vodo.
Later, Mandalore wonders why he abandoned Ulic (It was Aleema using the Force on him) and plans to rescue him as he is honor bound to do. He goes to Yavin 4 to get Kun's help.
Meanwhile, Kun has just sent his new apprentices on a mission to kill their old Masters.
Using a double-sided lightsaber, Kun and Mandalore rescue Ulic at his Senate trial, and Kun kills Master Vodo.
Nomi and Sylvar then travel to Ambria to study with Master Thon. Oss Willum and Crado attack. Oss is captured, but Crado escapes. Master Thon is able to turn Oss back to the Light.
Across the galaxy, Kun's other new Apprentices are successful in killing their old Masters.
Kun and Ulic then put Aleema and Crado in charge of the next attack and show them a new weapon to use. When Qrrl Toq, Dace Diath, and Shoaneb Culu enter their line of fire, Aleema uses the weapon. It explodes a nearby sun, killing the three Jedi as well as themselves. Aleema has died for her treachery and Crado for his failure.
The two Sith then attack Ossus. Jedi Master Ood transforms himself into a tree to protect the most ancient Jedi lightsabers from Kun.
Sylvar then attacks Kun, but is defeated by his Massassi servants.
Ulic kills his brother, Cay, and immediately regrets it. Nomi then uses the Force to block Ulic from touching the Force. He can no longer sense or use it.
Meanwhile, the Mandalorians attack Onderon, home of Lord Kira and Queen Galia, but are defeated and retreat to the Dxun moon, where they are killed by the beasts there.
Ulic agrees to take the Jedi to Yavin 4, where Exar Kun's base is.
Sensing Ulic's betrayal, Kun uses the Force and Sith magic to send his spirit into space so that he cannot be defeated. Fortunately, all of the Jedi create a Force barrier around the planet, unknowingly imprisoning Kun's spirit on the planet.
