About Galerians: Rion
In the 26th century, Rion Steiner awakens in a hospital to the sound of a girl's voice in his head. Unable to remember who he is, he uses psychic powers to break out and sets out to discover himself, and the truth behind those who are after him - the Galerians. Their mother Dorothy, the super-computer with a God complex, will not sit idly by, as he holds the only key to the program that can destroy her. [Witten by Ebo]
