Alliances

Used the search function buy didnt find the answer--

How does a guild get into an alliance, or how does a guild ally with Luxon/Kurzick?
Just bought a guild hall, and dont know what to do next.

Go to either HzH or Cavalon and align yourself. There are Allegiance NPC's in each capital.

Augh, so I gotta PvE?
QQ
edit: How far along is it?
and which campaign is it in?

Please excuse my ignorance, I ascended in prophecies soon after the game came out and quit the game until recently, and all Ive done is TA and RA.

You have to get about 60% of the way through Factions. Yes, it's stupid.
