Crystalvein Mine is located near Zul'Mamwe, and the native basilisks eat the strange crystals which can be found within this mine. This gives the reptiles their hardened skin. According to Crank Fizzlebub, these Singing Crystals were unique to Stranglethorn and quite valuable. The Venture Co. have moved into the area hoping to harvest the mine, but the basilisk infestation has made this impossible thus far. Outside crystallized trolls and humans can be found.
