The Goblin Laboratory or Laboratory was a type of building created some time after Second War when the Goblins abandoned the Horde. It allows for a player to hire Goblin Sappers, Goblin Zeppelins, and Goblin Shredders. These services were often key factors in various events during and after the Third War. Examples include allowing the Scourge to access more of Quel'Thalas via zeppelins, helping the Horde cut down much of Ashenvale forest via shredders in order to build Orgrimmar, and helping Thrall travel to the Stonetalon Mountains to meet with Medivh, also via zeppelins
