House zu helter.

How do i get there? Aparently i need to go there to do the fort aspenwood battles and stuff.

Its in Factions have a look here

So i have to do a whole campaign just to do some battles?

Those specific battles, yes. On a PvE character.

You can get a teleport to Jade Quarry and Fort Aspenwood from Great Temple of Balthazar (look around for Kurzick/Luxon NPCs). You just need to own GW:Factions.

Yeah but they tell me i need to talk to some guy at the house.

You will not be able to get there on a PvE character without first getting to House zu Heltzer.

Considering the fact that you have not reached this point in Factions, let alone completed it I expect you are not quite ready to play Fort Aspenwood.

If you insist on getting there then create a PvP character who will be able to map to Fort Aspenwood through the Great Temple of Balthazar by talking to a Luxon or Kurzick NPC.

Why would i not be ready :/

It's different for PvP and PvE characters.

PvP characters get access immediately.

PvE characters have to progress with the factions storyline before they're able to walk over to the mission outposts for FA and JQ. So, if you want to get there with a PvE character, you'll have to play the storyline to that point.

You sound like someone who should've started with pvp and skipped the backstory. It's not too late.
