Allegiance

Allegiance is a term that describes which faction your guild or alliance allies with. There are two factions. To ally with one of them, the guild leader must make it to the capital city of the respective faction. He must then talk to a faction ambassador:
 * Kurzick
 * Luxon
 * House zu Heltzer (Kurzick)
 * Cavalon (Luxon)
 * Kurzick Ambassador
 * Luxon Ambassador

Note: Both cities are located in Cantha and therefore, the guild leader must have Guild Wars Factions to take an oath of allegiance.
