Games : Trying to find the name of a rpg game

alright people of the stackexchange world, I am trying to find the name of a rpg game.I am going to try and explain it as much as I possibly can. So this game was on the ps2 or PS3 don't remember Which, probably PS3 In the title I swear it had the word dragon in it. So it starts of with a cutscene of a village burning down by people in black armor on horses he is walking forward trying to capture this one girl there is some stuff in between and there is another cutscene with a castle and some people staring off into the trees then a green dragon bursts through the trees and starts destroying stuff and you are hiking in the woods and here it then this one girl helps you out getting to the city. And along the way you have to chop down this tree thing. But anyways the game was spread over like 4-6 discs the graphics were ok I guess and you sometimes traveled on a big map other times it was screen to screen. Any ideas?
