Rappelz

Rappelz is a free-to-play massively multiplayer online role-playing game. Rappelz is set in a medieval fantasy world, dominated by three races: the Deva, who represent light, the Asura, who represent darkness, and the Gaia, humans that possess an affinity with nature. Each major installment of the game is referred to as an "Epic", similar to Lineage II's "Chronicles". The current installment is called "Epic 5: Dragonic Age".
