LPT: Quick teleport to Warlock Class Hall

In the Underbelly, there's a vendor named K'huta that sells portals within the Underbelly. For 150 Sightless Eyes, buy the portal at the Guard Station and the Rear Entrance. It places a portal in front of the Class Hall and the Guard Station.That way when you hearth to Dalaran, just turn left to the sewers, take the portal at the guard station and it will teleport you in front of the class hall, instead of walking all the way across Dalaran.
