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 and Gray Goblins. 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 at least one of the tribes is in thrall to Navrey Night-Eyes.
