|Goblins are one of the few groups in Azeroth that have remained unaligned. They have tremendous value to both teams, working as merchants or, in the case of the Horde, the single driving force behind the engineering program, despite how dangerous the slightest "innovation" they've made. They have been rivals of the Gnomes engineering program, which is safer (not by much). For example, The Gnomes made the Deeprun Tram, which resembles the modern day subway, while the Goblins invented the Zeppelins. During the War between the Orcs and Humans, the goblins worked only for the Horde, but eventually loaned their services to both sides.
