Rift (previously known as Rift: Planes of Telara) is a fantasy free-to-play massively multiplayer online role-playing game (MMORPG) developed by Trion Worlds. Rift takes place within the fantasy world of Telara. The game was released in March 2011. Two competing factions, composed of a selection of races and classes, battle each other and the enemies who emerge from dynamic "rifts". Telara is the focal point of the elemental Planes: Air, Fire, Water, Earth, Life, and Death—and one point where every one of these Planes intersect with each other. Each Plane is governed by a dragon-deity, a personification of that elemental force. Through the actions of the Dragon of Extinction, Regulos, the various dragons have united in an alliance known as the Blood Storm, for the purpose of invading Telara and gaining use of the intersection of all of their realms. In the past, the Blood Storm was defeated by the inhabitants of Telara with the help of the Vigil, the most powerful of the native gods. Rifts are areas of elemental instability that represent the intrusion of elemental planes into the land of Telara. Once opened, these rifts begin to spawn monsters that proceed to march towards important points on the map. It is up to players to defeat these monsters and to close the rifts. If rifts are left unchecked, the invading monsters will eventually conquer large portions of the map, inflicting casualties and significantly hampering the operations in that area. Entering the area around a rift triggers a prompt for the player to join a public group, rather than forcing the player to manually create a group. After sealing a rift, players are rewarded based on their contribution to the fight, such as healing, dealing damage, or buffing other players. The severity and locations of rifts are entirely dynamic. Rifts of six different types (earth, fire, air, water, life, and death) are possible, and rifts of different types will oppose each other. In addition, Non-player characters hostile to the player may engage rift invaders. With the addition of Storm Legion, Hunt Rifts can be summoned by players creating a "survival" style of combat where players defend conduits from waves of invaders culminating in a boss battle. Hunt Rifts have varying degrees of difficulty and as the difficulty increases the player rewards also increase.
