Mo'grosh

The Mo'grosh are a group of ogres that have taken up residence to the northeast of Loch Modan.

World of Warcraft
Many years ago, the presumed leader Chok'sul, has once coordinated attacks against the town of Thelsamar, the Stonewrought Dam, and dwarven excavation sites in the area.

A group of Mo'grosh ogres ambushed a dwarven caravan coming from the Wetlands, stealing Bailor's Ore and leaving no survivors besides a deadly-wounded guard.

Chok'sul's plans were eventually thwarted and he was killed during the retaliatory strike.

Cataclysm
Several years later, the Mo'grosh under the leadership of Gor'kresh, have alleged themselves with the nihilistic Twilight's Hammer that dwells in the highlands above and now seek to spread the destruction even further in the broken lands of the Loch Modan.
