How do I start an Adventure ?

[alpap]

I have the traitors adventure in my quests but not sure how you start it ???

[Sinister-King]

Open the star menu, select 'Traitors' and click start adventure.

I think though you haven't got the adventure, just a quest to complete it. In that case you'll have to:

Purchase from someone in /joinchat global-3
Purchase with gems from the gem shop
Hope your Explorer finds one.

Good luck .
