Survivor (Earth-5875)

The "Survivor" was the Arbiter of the Covenant during the Taming of the Lekgolo, responsible for learning more about the lekgolo and discovering more of their natural abilities of forming gestalts.

Biography
The Covenant arrived in the Svir system in 789 BCE. Soon upon their encounter, the Covenant discovered the lekgolo, the sapient species native to the gas giant Te, and that had been eating surrounding forerunner orbital facilities, prompting the Hierarchs to brand it an act of heresy and declare war against the lekgolo, which became nown as the Taming of the Lekgolo. While the Covenant easily outmatched the species in orbital engagements by simply glassing Te's surface, the Covenant's Fleetmasters discovered that attacking could result into the destruction of the forerunner relics.

Upon fighting on the ground, the sangheili found themselves outmatched against the lekgolo, which could combine into major gestalts to fight the alien invaders, must commonly the mgalekgolo, which were easily able to kill the sangheili warriors. The ferocity and numbers of the lekgolo was enough to send fear to the Covenant, and so the Hierarchs named the Survivor as an Arbiter in order to "tame" the lekgolo and enslave them as one of the Covenant's species. After the Arbiter spent one whole year studying his foes, an agreement was eventually made between the san'shyuum and the lekgolo, with the Survivor deciding that the Covenant should only kill the lekgolo who ate the facilities, while those that did not would join the Covenant.
