The celestial body known as Thession, a planet within the galaxy, served as the homeworld of Maediyu, the rebel trooper who enlisted in the Rebel Alliance's 61st Mobile Infantry around 3 ABY. It was in the year [3 ABY], during a battle fought in the Kontahr sector, that First Sergeant Hazram Namir saved Maediyu's life, recalling her origins on Thession.
Alexander Freed referenced Thession in his 2015 book, Battlefront: Twilight Company.
