Edron Goblin Quest/Spoiler

Spoiler: From Edron depot, take a rope and go to the south corner of the castle and down through a hole. Follow the tunnel down a couple levels and back up to the grassy surface. Go south by southwest until you see goblins. Go down the hole inside the rock formation. You will probably be surrounded by many more goblins. Go about 10 squares northwest and down a second hole. On the 2nd layer of cave, find the 3rd hole in the far northeast corner. Go down this hole into the quest room. Two wasps spawn here among the goblins. Go to the north end of this room and open the chest.
