The game is set in a kingdom, built using a mysterious substance known as Source. The builders of this kingdom, the Archineers, studied source in an attempt to better understand its properties. The greatest archieer was Agonius, who discovered a truly remarkable property of source – that it can emulate life. Agonius started creating lifelike beings from the source, but the King, who understood the dangers of this, demanded that Agonius halt his work. Agonius refused, and so was banished from the kingdom.
