Hobbit Chapter 4, Over Hill and Under Hill
[*The Great Goblin] (enemy)
Technically it is a title instead of a name, but since he has his own unique enemy card I've listed him anyways.
We learn in this chapter that while goblins hate Thorin's folk due to the war, they don't especially hate dwarves and have even made alliances in "some parts" with "wicked dwarves". Suppose we'll ever see dwarf enemies in the game? No, Nalir doesn't count.
More remarkable to me is the way that *all* the goblins recognized Biter and Beater. Elrond guessed that those blades have been out of circulation since the fall of Gondolin and had to read the runes to identify them; Gandalf didn't recognize them at all. Yet the goblins recognized both on sight. Goblins multiply, by all appearances much much faster than the elves they mock, even if they have the lifespan of elves (likely IMO), it's remarkable that so many goblins of the misty mountains would be veterans of the few battles involving Gondolin.
