Warcamp

From HammerWiki

A warcamp is an encampment found on the edge of each zone's RvR playing field. For each such playing field there is a Destruction camp, and an Order camp. A variety of services including a Flight Master, merchants, career and renown trainers, and quest givers can be found at each war camp.
You can purchase guild standards at warcamps, and siege weapons at Tier 2 and above warcamps.
