Wild servers are battlegrounds where different kingdoms clash together. There is no pre-owned land, it must be claimed by constructing guard towers. Deeds can only be placed within the territories claimed by the towers. Horde of the Summoned are only found on wild servers, having forsaken their original kingdom's home.
Full PVP is enabled between kingdoms, as well as internally in the Horde of the Summoned. Whitelight kingdoms do not currently allow internal strifewithin your own kingdom. The White Light and Black Light are found on the wild server.
GMs generally avoid intervening in wild server affairs. However, excessive griefing and other violations of the game rules will be punished as appropriate.
