Goblins
Goblins are a race of evil monsters found in the Underworld and in the Stygian Abyss Dungeon. They first appeared in the Stygian Abyss expansion.
They come in two varieties, Green Goblins ( Green Goblins, Green Goblin Scouts, Green Goblin Alchemists ) and Gray Goblins ( Gray Goblins, Gray Goblin Keepers, Gray Goblin Mages ). These two tribes of Goblins are at war with one another, and each side will offer Quests to players that involve killing members of the other side. Dialogue implies that Gray Goblins are in thrall to Navrey Night-Eyes.
