Xeltek was a Jedi Knight who served the Jedi Order during the Clone Wars. In the final months of the war, Xeltek was among the contingent of Knights sent to the planet of Saleucami to help stop the Separatists' cloning efforts. On Saleucami, Count Dooku entrusted the operation to the Dark Jedi Sora Bulq. On Saleucami, Bulq initiated a plan to use the sole remaining member of the Morgukai cult as the host for a batch of clones. The Morgukai, a fiercesome Nikto cult had oftentimes found themselves equally matched against a fully capable Jedi. Once the clones hatched, Bulq initiated the second phase of the process. The Morgukai clones were trained by none other than Anzati assassins, some of the best assassins in the galaxy.
The potential of such a plan was too great for the Jedi to take lightly. An army of Morgukai clones would have been capable of turning the tide of the war. Because of this, the Jedi committed some of their greatest warriors to stopping the Separatists from succeeding. The Jedi effort on Saleucami was led by Jedi General Oppo Rancisis. Xeltek was assigned to the mission and fought alongside renowned Jedi A'Sharad Hett, Aayla Secura, Jeisel, Durnar, and more.
Unfortuantely, Saleucami claimed a number of Jedi during the operation. Saleucami saw the deaths of Ausar Auset, T'Bolton, and even Jedi Master Oppo Rancisis. Xeltek was among them. After the death of Master Rancisis, the remaining Jedi held a ceremony by firelight to honor their fallen brethren who had become one with the Force. During the ceremony, Xeltek was honored by Jedi Knight Xiaan Amersu.
