How do you change zone?
Look at this map (gw2cartographers.com) Looks like you have to get trough Black Citadel.
Don’t see a link, but I find a map online and it seems there are in fact narrow passages. However, it seems that some section don’t connect so you have to go through other areas to get to the one you want. Can anyone confirm this?
That’s exactly how it works. Makes sure you enter the zone from the “right” (i.e. the “lower level”) direction
