Greymere's Gambit

If them Ogres south of here were to move against us it'd be a disaster! They might help the greenskins push us off Thunder Mountain and put a lot of good Dwarfs in the ground. There ain't no bloody sense in waiting around for that to happen. As usual, we cannot spare a single regiment. We have far more concerns than we have hammerers and thunderers to fix them. That means you're going to have to go out there and take on the threat yourself. Go there and slay their tyrant leader, and then return to me, and we'll see how we can reward ya.

Travel south to the Ogre Compound near Neckrender's Warband in Fire Ruin and slay the Bloodmaw Ogre leader, Tyrant Gulp Herdeater. Return to Athgar Greymere at Dragonslayer Ridge when you have completed the task.
