HistoryOr'agg, second in command of the Moz'zog camp has a history with Uboh. Show spoiler
Some time ago, while Uboh was still a member of the Moz'zog clan, he made a power play and lost a trial of combat with Or'agg. Uboh then fled and has not been seen at the camp since. After Uboh and friends rescued Gru'un and the other orcs they returned them to their home. Or'agg met them in the camp but at the orders of Gork-Al, ceased his hostilities for the moment.
