Yavin was the god of the Massassi, the warrior caste of the Sith species. He was represented by the gas giant Yavin Prime that filled the skies of its fourth moon. In the eyes of the Sith warriors, the red god was awe-inspiring because of his all-dominating presence in the firmament. When the Sith Lord Naga Sadow ordered the Massassi to assemble monuments, they found their own purpose in that command. In hopes of becoming like gods themselves, the Massassi built the temples in a vain attempt to reach their deity. Yavin was recorded in the Books of Massassi, a collection of sacred texts.
