The Vorenus Imperium was the last race to join the Alliance of United Races and is a unique race from the Crux-Scutum arm of the galaxy, from the world of Nalidine. It is made up of a rigid, discipline based society, born from years of internecine civil war. While only a similar age to the Human and Sangheili race, it is interesting to note that they have achieved Tier 2 Technology without artificial intervention (Forerunner relics for the Covenant, the Covenant for the UNSC.)
