The Inner Realm is the main "safe zone" of each realm. Most of the game's PvE content centers in this area, preparing players before they enter the War Zone. Each realm has a great wall that separates the War Zone from the Inner Realm. This wall normally keeps players safe from enemies, though through invasions, enemy players can sometimes break down the gates of each wall and raid the Inner Realm. In such cases, it may be best for lower level players to retreat into the heavily-guarded towns and cities.
