The Heliost Clan represented just one of numerous clans where young initiates found placement within the Jedi Temple located on Coruscant. Their primary instructor in the art of lightsaber combat was Jedi Master Tera Sinube, and notable members at one time included individuals such as Gretz Droom, Ky Narec, and Qui-Gon Jinn.
The Star Wars canon saw the reintroduction of the Heliost Clan in the original audio book Dooku: Jedi Lost, which was penned by Cavan Scott in 2019. Initially, the Heliost Clan was conceived for the Star Wars Legends reference guide The Jedi Path: A Manual for Students of the Force that came out in 2010.
