- ^ Halo: Evolutions - Essential Tales of the Halo Universe "The Return" - "It was a terrible war. The Prophets provided the Brutes with powerful new weapons, hoping that they would in turn defend their Prophets against our wrath. But when the Prophets went into hiding, the lack of leadership allowed the Brutes to return to their savage nature and they soon began to fight against each other. This lack of solidarity made them much easier prey. Some of my fellow commanders continue that fight even now"
