Aion is a Massively Multi-Player Role-Playing Game (MMORPG) that was created by a Korean developer. Throngs of online players gravitate to the game because of its complexities, its imaginative characters, and because players can create the essential features of each character, i.e., the voice, face, build, skin-color, type, etc. Aion created human beings and employed Balaur to keep an eye on them, yet Balaur became power-hungry, which places this character in a direct parallel with Satan. In the process of Balaur's obsessive campaign, five of his underlings gained super-human strength and became Dragon Lords, but Aion did not let them keep their power, and so these pesky underlings revolted against their creator. At that point Aion was forced to create Lords of Divinity to watch over the Tower of Eternity.

The plot is much more complicated but basically players are thrust into the game as inhabitants of the world of choice: some will pick Elysea, and others will pick Asmodae. At first, tiny, seemingly-unimportant tasks are given to the raiders until they are completed correctly. At that point, after stopping Balaur from being brought again to the beginning area, they hopefully get their wings and become immortalized Daevas. From this moment on the new life purpose for these Daevas is to protect their people by fashioning themselves as holy servants. The tone of the game differentiates immensely among the worlds. The environments and landscapes also change dramatically but the major progression and rhythm of the game remains the same.
