Cosmowrench is a tiny goblin outpost located in the Vortex Fields in the easternmost part of Netherstorm, very close to Tempest Keep. It resembles a miniature version of Area 52. Originally, only the flight master Harpax was present here, but others were later added. The outpost's only building is an unmanned barbershop containing only a Barbershop Chair.
