Yull

Yull was an Unggoy stationed aboard the Rapid Conversion and was part of Dadab's group. He was the first true Covenant casualty of the Human-Covenant War.

Biography
He was one of the Unggoy who Dadab had attempted to teach, and as such was one of those picked by Chieftain Maccabeus to accompany him to the parley with the humans on Harvest.

After discovering the human colony of Harvest, the Covenant believed it was home to numerous Forerunner artifacts. Yull was one of the Unggoy to land on Harvest's surface when the Covenant and humans attempted to make a peace treaty. He became nervous when he saw humans and killed Osmo by jumping on him, biting and clawing at him, ripping his stomach apart. He was then killed by Tartarus, who pulled off his mask and threw him into a whirlpool and down a series of waterfalls because he threatened the Jiralhanae's plans. He would die of suffocation. After the incident which led to the beginning of the War, Maccabeus coldly informed Dadab of Yull's death, and of how apparently his "teachings" had ultimately been useless.

Flim later mocked Yull, claiming he was stupid.
