Ry'Gorr Mining Operations

Steps

 * 1) Look around for a Ry'Gorr Explosive Mining Barrel and use it on the wall I discovered. Head up further into the cave, the first barrel I saw was 224,-50,106.  I could see at least 2 others in the cavern.  Barrel is a gather.
 * 2) Back down to the cave-in wall, a message pops up saying "This seems like a good distance to place the Ry'Gorr Explosive Mining Barrel." Right-click to Use the barrel.  Back up and in 3 secs it blows up the wall.
 * 3) "With the wall destroyed, I should investigate what is on the other side."  Quest updates about 5 steps in.
 * 4) Return to Thirin's new loc.
