Ok. Here is how you get to the final boss (Lord Xin) First you must get al the heartstone pieces, then you must complete the final quests for all of your 3 allies. After that go to the Alliance that are next to the cave in the top right and accept their quest. Now go down 5 spaces and across 3. to get to the final fight.
