Arad is a story of a forgotten son who returns to his supposed place of birth, only to find himself unwelcome. He is captured as a defyer and is brought to the king for "purification". His soul must be purified before Marduk, the God of time. But Arad survives to become something that he can never forgive. The story takes place 4500 years ago in the lands of Sumeria, only a few centuries after the birth of civilization and the destruction of the tower of Babel.
