Janton Belos was a male Force-sensitive being who was part of the Sith Empire during the era known as the Golden Age of the Sith. Belos rose to the rank of a lesser Sith Lord and chose the Near-Human Valik Kodank to be his consort. Wishing to keep her happy and maintain her romantic interest, he provided training to Kodank in the teachings of the Sith. Kodank's power increased, and she hid her newfound abilities from Belos. Unbeknownst to him, she engaged in an affair with another Sith Lord and established her own group of devoted sect followers.
The character of Janton Belos initially appeared as an unnamed Sith Lord within Child of Light, a Star Wars Legends roleplaying adventure created by Lee Pickler and released by RPGA in 2000; it served as the first part of the Child of Light saga. He was later referenced in the third adventure of the Child of Light saga, titled Light and Dark, in 2002, where his name was revealed. Neither adventure specifies Belos' species.
