Greetings,
PC is Paludal Caverns, and is off Shadowhaven on Luclin. There is also a connection at the other end of the zone to Shadeweaver's Thicket (Shar Vahl newbie zone).
You will gain experience there quickly, but you will also experience some of the worst behaviour!
KSing, camp stealing and trains abound - but if you can get a decent group and grit your teeth, it will be over quite quickly...
Hope this helps.
