I used to be an operative for the Silent Shadow, a special branch of the Covenant. I was marooned on a planet called N'ba with a few other Sangheili and spent over a thousand cycles there. I lived with them in an underground Forerunner structure called a tel, where I indulged myself with the food it provided, to the point where I became quite fat. Luckily I was found by the Arbiter, and I have just been brought back to my home, where I can relax, and eat more food.
