Sooln 'Xellus

Sooln was Sangheili rebellion leader Ussa 'Xellus' mate during the early years of the Covenant. She expressed much distaste for the Writ of Union and traveled with her mate to unite the Sangheili against the San'Shyuum.

Biography
In 851 BCE, Sooln was forced to flee the state of Xellus with her mate, Ussa 'Xellus, and any surviving Sangheili after Xellus keep was attacked by Covenant fighters due to Ussa openly opposing the San'Shyuum and the newly formed Covenant. Sooln and her clan fled to the Nwari region at Sanghelios' southern pole. After fortifying a base of operations in a dormant volcano in Nwari, Ussa and Sooln travelled to the Sangheili mining colony of Creck to recruit new members into their resistance. The first day was unsuccessful. While returning to Ussa's ship, Clan's Blade, at a spaceport, Sooln noticed an elderly Sangheili following them. However, the Sangheili was slow and unable to keep up, so Sooln did not call him to attention. The next day, the two attempted to recruit followers in the mines of the colony, but with no success. Sooln and Ussa returned to Clan's Blade to leave Creck, but encountered the elderly Sangheili, 'Crecka, waiting for them at their ship. 'Crecka convinced the two that he wished to serve with them and claimed to know of a Forerunner world, Shield World 0673, that Ussa and his insurgents could use as refuge. Intrigued, Ussa and Sooln had 'Crecka lead them to the world.

The three travelled to the shield world and entered its interior. After landing, they explored the world's artificial ecosystem until they encounter Shield World 0673's monitor, Enduring Bias. The monitor agreed to allow the Sangheili to live on the world in refuge, as long as they informed it of their intentions. The Sangheili were able to convince the monitor and Ussa returned to Nwari, Sanghelios to transport the rest of his allies to the shield world.

Personality and traits
Sooln was wise and considered slightly arrogant and bold for a female Sangheili, however Ussa 'Xellus described her as delicate and petite. She was regarded as a highly intelligent and analytical individual that was especially talented in the field of science. Sooln despised the Covenant, believing that the Sangheili were surrendering to the San'Shyuum.
