Check the last page. I've seen a Goliath 2 places in there. Up in the top middle area just before going down a ramp to the left that leads past the crystal creatures and at the bottom of that ramp after killing the 5 or so rats that spawn. The one at the bottom of the ramp is the one I got the quest from. Also, the quest involves killing "midgets" for part of it and I had just cleared out that area of small people when I first killed a Goliath that dropped nothing. Once I re-logged and the little people were spawned again, then the lower area Goliath dropped the item I needed. Not sure if that had something to do with it or not.
