Ter-adon is an ancient world with three kingdoms. As an enemy force begins to conquer the land, the world itself starts to suffer adverse effects due to the lack of a key element that once kept the world protected. This missing element must be found before being invaded and destroyed.

A new continent is discovered and the dwellers of this land suffer a mortal plague that ravages and destroys all form of life. A chosen few are called to bring the elements that are necesary to restore the land, but they must face a beast and its followers in the process.
