Legend of Litia Continent
Once upon a time, Eldarin, the only god of the Continent of Litia, created the tribe called Dragas, who were meant to rule the continent. The Dragas, who were masters of Rune and Magic, gradually became arrogant and eventually tried to steal the power of Eldarin using a powerful rune artifact., Eldarin, however, destroyed the artifact, and the Dragas' effort to steal her power was thwarted and they were banished from the continent.

Aterion
When the rune was destroyed, its dust covered the continent of Litia and created amazing creatures called Aterions, who are able to absorb the power and energy of others. Aterions, naturally belligerent and born to be warriors, thrive in as a center of human tribes after the decline and fall of the Dragas. In the Infinity Online, you play as an Aterion with two goals: in the short term, you wish to simply win battles with others; but your ultimate goal is to gain the ultimate power: the power of a god!

Soul Arena - The First Step To Becoming A God
Belronium, the famous magic guild of Granus, developed items with magical powers using the rune stone, a relic of Dragasus civilization. They became rich by selling these magic items and built a city in the sky called Caletium. One day Belronium held a fighting match called 'Soul Arena' and only Aterions qualified for participation. Now it's your turn. Take your place in the 'Soul Arena' and win a series of battles against opponents for a glorious victory. This is the first step to becoming a god.
