The tribes of troll based near blood elven land are all hostile, if the blood elves would kill them, burn their village and poke the troll leaders eyes out, the troll must have done something to bug the elves, not like a nudge, like a punch in the stomach, but all it really comes down to is showing off power to the other tribes to hopefully get the message across to stay away and to keep their people safe from the threat of the trolls. I have a question, if they poked his eyes out and chained him to a ruined structure, he must have been blind and they would have disarmed him (otherwise whoever was in charge wasn't to bright) how did he manage to pick up a spear?
