History
Prior to the Great Schism, Jul 'Mdama was a Shipmaster in the Covenant Forces. After the downfall of the Covenant Empire, Jul returned to his keep in 'Mdama, debating how Sanghelios would be run now that the Prophet Hierarchs had betrayed them and been driven off. His wife, Raia, however, was more concerned with how the Sangheili would rebuild in agriculture and engineering.

Jul ultimately sided against Thel 'Vadam and his movement, the Swords of Sanghelios, forming a Covenant remnant faction continue the fight against the UNSC. 'Mdama's forces later managed to gain access to the Shield World Requiem, where they unearthed the Didact and his Prometheans.
