A Force-sensitive Human, Sedni Maruk was trained in the ways of the Force by the Jedi Order, failing his Trials of Knighthood and remaining in the Order without a rank. Following the Great Galactic War and the resurgence of the Sith Empire, Maruk returned to the ancestral Jedi homeworld Tython with the rest of the Order and helped rebuild during the Cold War.
When he failed as a Jedi, the Jedi High Council allowed him to remain with the Order and stationed Maruk at the ancient ruins of the fortress city Kaleth. During his time there, Maruk became increasingly distressed at the number of horranths plaguing the region.
