Getting to house zu heltzer

Hey guys
probably an easy question for you
I got factions the other day, basically cos i wanted to get kurzich armor on my warrior, anyway ive been playing it.

I got to Altrumm ruins, and the gate there is closed, so i guess i have to carry on doing the primary quests and missions right?
well the primary quest took me to a Luxon mission, which kinda confuses me.

I was wondering if anyone could give me a liste of the things i have to do, After Altrumm ruins, in order to get to house zu heltzer.

Would be cool if somebody could

thanks a lot

1. Do the Luxon mission (Boreas Seabed)
2. Follow the next two primary quests (City under attack and Battle in the sewers)
3. Do the next mission the quest leads you to (sunjiang district)
4. Upon completing the mission, take the quest Journey to House zu Heltzer from Jamei in Maatu Keep.
5. If you followed the direction on the quest, Journey to House zu Heltzer, You should be in house zu heltzer by now.

thanks a lot
