Yeg

Yeg was a Covenant Jackal stationed aboard the Pillar of Autumn crash site during The Battle of Installation 04. After a raid by the ODSTs led by First Lieutenant Melissa McKay, he was assigned to inspect and haul cargo coming into the crashed vessel for use by the Covenant who occupied it. This was to make sure that Flood did not infiltrate the vessel.

He was placed under the command of Yayap after the Grunt arrived at the site following a failed battle at Alpha Base. He did not like the Grunt, calling him a "Gas Sucker" and "Methane Sucker." Nevertheless, he complied with the Yayap's orders because he had no choice. He, along with Jak and Bok, tried to make Yayap's life difficult nonetheless.

After Bok was killed by a group of Flood hiding in a cargo pod, Yeg suddenly became much more respectful of the Grunt. It is unknown what happened to Yeg although he was likely killed when the Master Chief detonated the Pillar of Autumn's engines.
