Venture Company Mining

The Venture Company has a string of operations through Stranglethorn which keeps hard-working goblins, like me, from making honest gold! Please, you must help me! The Venture Company is mining near the Crystalvein Mine to the north. They can't get into the mine because of all the basilisks, but they're still able to dig up Singing Crystals from the surrounding hills. Take their crystals from them, and show them they don't have the run of the jungle. And... um... bring me those crystals as proof!
