The Temple of Waru served as the dwelling place for Waru, an entity originating from a different dimension. Waru's arrival in the galaxy was triggered by disruptions in the Force emanating from a crystallizing star, coupled with Hethrir's acts of torturing his captives, many of whom were offered to Waru as sacrifices within the temple. Hethrir sought out Waru with the ambition of achieving mastery over the Force and, as recompense, intended to sacrifice the young Anakin Solo in the temple. Nevertheless, Hethrir met his demise during a battle against Han Solo, Leia Organa Solo, and Luke Skywalker.
