Timeline
The only other thing known about the Rebellion is that it involved the smallest and most common form of the Covenant, the Grunts, rebelling against the rest of the Covenant. Because the majority of the warriors and workers of the Covenant appears to be these 5 foot tall aliens, this event would have been extremly hard to deal with. It is not known when the Grunt Rebellion took place, but it is a famous event in the History of the Covenant. An Arbiter was created to deal with the rebellion, and it is assumed that he was eventually killed.
