Sawel and Seola, two souls are competing against each other over the ultimate exploit of human control. They are seeking new hosts to enter them, to use them and to control them. Before TIME, the souls were formless shadows, less than vapor, yet more than vacuum. They drifted from infinity to galaxies and from one planet to the next, until they finally found earth. First, they joined with creatures of monstrous size, unable to control and exploit them. Later, they merged with bland and placid creatures of the aquatics, but they were no challenge to the souls. At last, around 1,800,000 BC, they found two babies with marginal intelligence. They entered their fragile bodies and used them for their ghastly needs to sustain combat, until the twins died. At 3,000 BC, the souls found two Sumerian kings and they directed them into vicious and mortal combat. At 50 AD, the souls were responsible for the death of a Briton Businessman and his Roman lover by driving then beyond their capacity to sustain conflicts. At 4,000 AD, Seola found a fourteen-year-old girl without a soul and it was a challenging job for Seola to control her. At 100,000 AD, the souls learned about the distant future and their advanced ways of living in a sterile environment. They succeeded there also.
