Elite Mission

From the Factions FAQ:


 * The most powerful alliances have access to new areas that are designed to be the ultimate cooperative challenge.

There are only two Elite Missions in the Factions Campaign, one for each faction.


 * The Deep can be accessed though Cavalon. Only the alliance that owns Cavalon can get you past the Luxon Guards.
 * Urgoz's Warren can be accessed through House zu Heltzer. Only the alliance that owns House zu Heltzer can get you past the Kurzick Guards.
