Ok Decided to ask the ??? Where and when do I go to become a warden. I am lvl 13 druid at the moment and was wondering what I need to be looking for.
I believe at level 19 you will get a Hallmark quest (like you did at level 9) which will send you to the person who will give your trial and let you choose.
Starting at level 18 you can do the quest; starts with Aurora in North Qeynos if you want to start it before you reach 19 and have it show up in the journal.
