Cabal Online (Korean: 카발 온라인, stylized as CABAL Online) is a free-to-play, 3D massively multiplayer online role-playing game developed by South Korean company ESTsoft. Different localizations of the game exist for various countries and regions. Although free-to-play, the game makes use of the freemium business model by implementing an "Item Shop", both in-game and via web, allowing players to purchase special premium coins using real currency, in order to acquire exclusive game enhancements and features, useful items and assorted vanity content.
Cabal Online takes place in a fictional world known as Nevareth, nearly a thousand years after its devastation by a powerful group of idealistic men, the CABAL. Hoping to turn their world into a utopia, they inadvertently fueled the forces and laws of nature to rebel against them, causing the event known as the Apocalypse. After the destruction, only eight members of the CABAL survived, including their leader, Faust.
