So again, don't post spoilers, but i want to know, when i finish the quest line, are their radient quests like go take back a fort or something or is it done?

the latter

Also, you were supposed to attack each city, but they cut that out. Seriously, attacking random forts and then claim the city is taken? How lame. Then they don't even add any radiant quests to clear out random pockets of opposition.
