The Gravan Monastery, alternatively called the Grava Monastery or the Grava Asylum, functioned as a mental institution situated on the moon of Grava. In the High Republic Era, Jedi Master Tera Sinube facilitated the admission of Lavalox Verzen into the asylum's care. Furthermore, during that same period, Jedi Knight Azlin Rell found himself a patient within the asylum's walls following his harrowing encounter with the Nameless during the tragic Night of Sorrow. In the Imperial Era, operational control of the asylum was assumed by the Galactic Empire. Before the Battle of Yavin, Imperial Admiral Ruas Fastent received what amounted to a forced retirement, being unceremoniously placed within the asylum. Subsequently, control shifted to Fyzen Gor's organization, the Brotherhood of Wire and Bone.
