Memnarch found a spot of black oil on the floor. The Guardian promptly cleaned it up, but somehow, the oil found its way into his systems. As the oil entered his power matrix, Memnarch suddenly experienced a series of thoughts, which proved wrong everything he held dear. Then he knew that Karn was wrong in naming the world Argentum. He knew that Karn was wrong in creating the world as a sterile and metallic place. Memnarch would bring life to the world. The people would be his people. He would rename Argentum as Mirrodin and be its god.
