"Not just centuries. Millennia. As for the Shadow Realm, one of the reasons it's so large is because it's merged with the Spirit World. Malik figured that out shortly after he and Bakura came to Dominion. It's one of the reasons we can use it to travel from place to place quickly. Malik says geography in the Spirit World doesn't match up to geography in the real world, so it's a quick way to get places that are physically far apart from one another."

"The Shadow Powers, though," Yugi says, thoughtfully. "They travel in bloodlines. As long as people still manifest them, the Shadow Games have a way of drawing power. And with nine separate people manifesting them when Yami was alive, each of them with families... they'll have lots of descendants at this point."

Yami nods. "Including the Mutou family," he says, winking at Yugi. "Atanu probably manifested Shadow Powers when he was a teenager. After I died." He shrugs. "Bottom line, the Games had a way of drawing power, through the continued manifestation of their Powers in our bloodlines."
