You need to be an ally of two other fractions (like the blademasters), they give you more quests. You have to do several quests (kills on other fractions^^) to get an "ally" status, the other fractions will be on "kill at sight" status then^^.
Im an ally with alliance, warders, and commoners and kill on sight with all the others. How do I get the quest to fight the bosses in the mountains? The guy at the alliance camp doesn't have a quest for me.
