Cabal

Cabal Online (Korean: 카발 온라인) is a free-to-play, 3D massively-multiplayer online role-playing game (MMORPG), developed by South Korean company ESTsoft. Different versions of the game are available for specific countries or regions. Although Cabal Online is free-to-play, the game has a "Cash Shop" which allows players to purchase game enhancements and useful ingame items using real currency.
The game takes place in a mythical world known as Nevareth, which was destroyed by an evil entity known as the CABAL. Out of the survivors, six "Masters" rose up, each wielding the abilities of the "Force Power". These masters taught the people, and Nevareth was rebuilt. Years later, the CABAL is plotting a return to power, and the characters of the game take up the role of heroes who battle the CABAL uprising and conspiracy.
