The Battle in the Obsidian Citadel was a relatively short skirmish between Darth Malign, his New Sith Order and agents of the Jedi Order that occurred in late 17 ABY. The exchange began when Malign kidnapped the family of rising Jedi Enb'Zik; Malign twisted his family, encasing them in specialized capsules and performing experiments on them through the use of Sith Alchemy. Enb'Zik was eventually invited to the Citadel by Malign himself to have his family returned to him. However, Malign planned to use the situation to turn Enb'Zik to the Dark side of the Force.
