Alliance

Alliance is a feature that will be rolled out with Guild Wars: Factions, though as a feature and not a content, it will also be available to players who only own Guild Wars Prophecies.

Alliances are formed between guilds. Each alliance can be comprised up to 10 guilds. Members of allied guilds can talk to each other using the the alliance chat channel, and can visit each other's Guild Hall and participate in scrimmages. Players who own Guild Wars Factions can also participate in Alliance Battles in Cantha.

Alliances can control outposts in the game. Control is based on Alliance Rating, though it is not determined exactly what alliance rating gives control of an outpost. Possibilities include that the highest alliance rating on a particular side gets the "capital" (Cavalon, House zu Heltzer), and the next highest alliances get the next farthest away buildings from the capital.
