Bouldercrag the Rockshaper at Bouldercrag's Refuge wants you to free 6 Captive Mechagnomes and kill 3 Stormforged Taskmasters.
8x Attempt to free Captive Mechagnome
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, [player], and set these creatures free from their bondage. Ask if they would fight alongside us against iron dwarf tyranny.
