Lost my way in Factions !!!

I got to the House Zu Heltzer and ended up doing a zillion quests, both Kurzick and Luxon..now I've lost the story line and don't know to get back on track to finish the game. Is there somewhere I can look up the order of play, or can someone tell me what towns/outposts I need to visit for the last fight with Shiro ?
thanks

You need to take the quest either Befriending the Kurzicks or Befriending the luxons, and get 10 000 faction from either side you picked, then when you finish the npc will give you the quest which will take you to the next mission and then you're on, its pretty simple, hope that helps.

First if you open your quest log (the L key) if you have a quest labelled as Primary, that one will take you along the storyline. Alternatively to that, you can visit www.guildwiki.org, there is a complete walkthrough of both prophecies and factions games, look for mission guides.
