Goblin

Goblins occupy an uneasy place in a dangerous world, and they react by lashing out at any creatures they believe they can bully. Cunning in battle and cruel in victory, goblins are fawning and servile in defeat, just as in their own society lower castes must scrape before those of greater status and as goblin tribes bow before other goblinoids.
Goblins know they are a weak, unsophisticated race that can be easily dominated by bigger, smarter, more organized, more ferocious, or more magical creatures.
Goblins seek to trap and enslave any creatures they encounter, but they flee from opposition that seems too daunting. For miles around their lair, they employ pit traps, snares, and nets to catch the unwary, and when their hunting patrols encounter other beings, they always look for ways to capture their foes instead of killing them. Goblins that run up against the fringes of a society first test its defenses by stealing objects, and if these crimes go unpunished, they begin stealing people.
Enslaved creatures receive the worst treatment the goblins can dish out while still getting decent performance out of the slaves. But humanoids and monsters that are especially capable or that provide unusual services find themselves treated like favored (though occasionally abused) pets.
Virtually any kind of creature that can be browbeaten into service might be found with a goblin tribe, but rats and wolves are nearly always present. Both have lived in concert with goblins for at least as long as people have worked with dogs and horses, and in goblin society those two animals serve similar purposes.
