The presence of a fire elemental here in Coldridge is no small matter. That earthquake did more than just upset a bunch of troggs... it changed the world enough to tear a gash into the elemental plane. We should submit a report to Ironforge.
You wouldn't be willing to take a trip, would ya? Don't worry, I've a feeling you'll do just fine. Talk to Hands Springsprocket by the tunnel on the eastern edge of the valley. He'll point you in the right direction.
