Slaves of the Stormforged

To the southwest, on the western side of the Snowdrift Plains, the iron dwarves have dug a mine into the hillside. There, they use captive mechagnomes, servants of Keeper Mimir, to mine ore. I don't know where these mechagnomes came from, nor what they would do with their freedom, but perhaps we can win their help. Go to the Frozen Mine, <name>, and set these creatures free from their bondage. Ask if they would fight alongside us against iron dwarf tyranny.
