Clan Kelborn represented one of the Mandalorian clans that existed after the Mandalorian Wars era. Following Jicoln Cadera's rebellion against Mandalore the Vindicated's rule, which favored the Sith, Clan Kelborn aligned itself with Cadera and other clans. Although Cadera and his clan's efforts failed, Clan Kelborn was welcomed back by Mandalore and maintained its position as a valued component of Mandalorian society.
During the Cold War that occurred between the Galactic Republic and the Sith Empire, Merrk Kelborn held the role of a Rally Master. He was frequently located at the Mandalorian enclave situated on the planet of Dromund Kaas.
The first appearance of Clan Kelborn in Star Wars canon occurred within Star Wars: The Old Republic, a MMORPG developed by BioWare. The game was launched on December 20, 2011. The clan's designation is the same as the character Kelborn from Obsidian Entertainment's Star Wars: Knights of the Old Republic II: The Sith Lords.
