need a Group for Arah Dungen
Try gw2lfg.com which should help
I’d be glad to run you through the story. I’m sure a few of my guildies wouldn’t mind either.
The story is anti-climatic and if I recall it was also pretty unrewarding as well. The good thing is it didn’t take very long to do and was fun to see zhaitan. Be persistent on gw2lfg and you’ll eventually find a group.
