The story of Aion: The Tower of Eternity is rife with conflict between factions. Harboring centuries of hatred, the Elyos and the Asmodians are now at war with each other, with nothing less than the fate of their entire people in their hands. Large fragments of Aion, floating in the Abyss that separates the two halves of the shattered world, serve as battlefields between these two factions. Players will venture into these areas as they attain enough experience in their own lands through a series of portals or Gates. They may even venture into enemy territory.

The factions constantly battle for various fortresses and artifacts within the disputed areas of the Abyss. Each of these captureable areas garner various bonuses and special resources to the controlling side, and certain items can only be obtained from vendors operating out of these areas. In addition, players can accumulate points and special ranks by defeating other players, and then use these points to acquire better equipment.

The Elyos and the Asmodians won’t just be battling each other in the Abyss, however. A third faction exists, the ancient enemy known as the Balaur. Depending on the situation, players may end up battling the Balaur as well as other players, or there may be times when the Balaur can ally with one faction and fight the other. Other lethal denizens of the Abyss may also come into play. This is the heart of Aion’s PvPvE system.
