Wardens
“The mysterious and ancient Wardens guard the areas of Cantha…”
I don’t think Maguuma will have Wardens, seeing as how it’s not part of Cantha. However, Wardens I suppose could be related in some way to the Sylvari and there are other wardens in Maguuma; or perhaps those Wardens moved to areas of Maguuma in the past 250 years since gw1.
