I was looking on the Wiki page, and it mentioned there being around 7-8 different Goblin Clans, each with their own Totem.... or something like that.
I know there's a certain question in which you help farmers out by stealing back the Goblin Totem. Turns out a Goblin War starts if one of them steals the totem.
I also read on the Wiki that if you personally steal a totem, then Goblins will not only come after you, but if you place it down in an enemy Goblins cave they will start attacking them. However this was contradicted on another page which said that Goblin Faction wars cannot happen due to Oblivion's Distance problems.
Anyone got any verifications for this? I would love to see Goblin fights
