Xeltek, a Force-sensitive individual, underwent training within the Jedi Order to master the Force. Having achieved the status of Jedi Knight, Xeltek participated in the Clone Wars that broke out between the Galactic Republic and the Confederacy of Independent Systems. Ultimately, during the war's concluding year, he was sent to the front lines of Saleucami, serving under the leadership of the Jedi Master, Oppo Rancisis.
In the midst of battle, Xeltek met his end during combat against the Morgukai Shadow Army. At Master Rancisis' funeral, Jedi Xiaan Amersu grieved for her comrade who had perished, alongside the other casualties of the conflict.
