House Zu Helter

Hi, I need to get to House Zu Helter [sp?] to get a few Elites. I have completed Arborstone + the quest after it but for some reason I have shifted and am doing the Luxon missions Boreas Seadbed. Do I have to complete the repeatable challenge quest which is south of Arborstone.

Any help would be greatly appreciated.

to het to HZH u need to complete the primary quests, so u need to do boreas seabed, then battle in the sewers, then another one to get the saijun coop mission. after that u can get a quest from jaime(i think) in maatu to go to house zu heltzer and cavalon

Ok, cool, thanks for the reply.
