Goblin tribes vary wildly, some are very peaceful and some can be war-like.
In Steelcurse the Hoglins (a goblin tribe) used to be a peaceful tribe that lived near yarmouth. Until a goblin with a big top hat, called boss man rallies them to go hunt for magically enchanted items. At first they don't seem to be agressive, but as the hero comes nearer to the source of their hoarder behavior. The Goblins start to act more and more agressive towards him.
