As Mark stared in the mirror, he saw the wall behind him shimmer and brighten. An opening was forming, but instead of the outside of the house, he could see an open, sunny plain with huge, shaggy cows grazing. Buffallo? He turned, fascinated, and started walking towards the passage. He could smell the earth, feel a warm breeze coming fom the field.
"Mark! Where are you going? Get away from there!" Sei ran to stop Mark from stepping through, only to trip on one of the scattered toys and fall through himself, knocking Mark to the ground. There was a strange pulling sensation, and then the room disappeared.
Mark scrambled up first, looking at the unbroken expanse of grasslands and forest. Then he looked back at Sei and blinked. His freind looked different! He was starting to change to fit into this world of Indians and buffallo!
