Battle on Had Abbadon

The Battle on Had Abbadon took place in 137 ABY, and was the result of a trap set up by a mixed band of both Jedi and Imperial Knights to assassinate Darth Krayt, Dark Lord of the Sith and reigning Galactic Emperor. The battle commenced after Krayt's Imperial garrison was attacked on Had Abbadon by the group of Knights, and one of Krayt's servants, Darth Reave, was allowed to escape in order to inform Krayt that Jedi Cade Skywalker was among the perpetrators. Krayt was also summoned by Karness Muur—whose spirit inhabited Jedi Master Celeste Morne, Skywalker's other associate. Muur offered to heal Krayt of the Yuuzhan Vong implants that were killing him in exchange for a partnership in galactic rule, only if the Dark Lord came alone to Deep Core world. Krayt did not follow Muur's instructions, and instead arrived on Had Abbadon with Darths Maladi, Stryfe, and Talon, with his lieutenant Darth Wyyrlok remaining behind on their ship. In spite of Krayt's defiance, Muur still chose to demonstrate his healing power. It was at this moment that Jedi sprung their trap with the Imperials, engaging Darth Krayt and his Sith Lords in battle.

Morne commanded her rakghoul mutants to attack as she dueled with Krayt. Imperial Master Azlyn Rae seized an opportunity to cut the Dark Lord down, and mortally wounded him. Morne then subjected Krayt to a lethal torrent of Force lightning, inadvertently engulfing Rae as well. The battle appeared to be over when Krayt seemingly fell to his death, and Celeste Morne was slain by Skywalker, after she asked him to free her of Muur's spirit. The Jedi and Imperials then collected their wounded, and fled Had Abbadon. Meanwhile, Darth Wyyrlok landed a shuttle planetside to collect his defeated Sith brethren, where he also found Darth Krayt to be alive. When the Dark Lord requested that Wyyrlok tend to his injuries, the Chagrian instead defeated and presumably killed him. However, after suffering severe injuries at the hands of Wyyrlok, Krayt was resurrected and soon revealed his existence to the mutinous Sith.
