The Temple of the Highlord was a large orbiting space station that existed within the Anti-Matter Universe and was a facility created by the Qwardians. Hovering in orbit of the planet Qward, it served as the headquarters of the Highlord and leader of the Qwardian Empire thus serving as a base of operations for the elite Weaponers of Qward. The space station included a command chamber as well as a detention grid that made use of yellow light energy beams to imprison captives. At some unknown point, the Korugarian supervillain known as Sinestro managed to subvert the Weaponers and became their master where he established a base of operations from the Temple of the Highlord. It was from this location where he planned to get his revenge against the Positive-Matter Universe and the Green Lanter
