As soon as his foot touched the ground outside, Mike stumbled as his body and mind were suddenly pulled, twisted, and compressed. He cried out in pain and fear as he landed in a heap, only to have the terrible sensations end a moment later. It was immediately obvious that the body swap had been complete as far as the magic was concerned. He was a naked, filthy little boy with long, matted red hair. It was more than just the look. He was confused, and while he could remember what had happened, being this child seemed... normal. The sounds of children playing caught his attention, and he wanted to join them.
From the stable he heard a shout and then a laugh, and had to jump out of the way as a huge black centaur trotted out. The centaur was odd looking, his face very horselike and his upper body covered with patches of fur that matched his animal hide. His arms hung limply to the sides, but after a moment of concentration, he raised them up and flexed powerful hands. "It just takes more effort! Thank you for this!" The centaur grinned down at him. "I am going to go back and rejoin 'my' friends for our adventure. And when it is over I will go back to the other world and live my life there." Even as he spoke, the two of them felt the weight of reality settle back into place around them.
Aaron blinked up at the centaur. He knew that had been him, but the concept was already seeming more like some silly game he had been playing.
Mike stretched out his arms, reveling in the strength he had missed for so many decades. Then he frowned, the memories of being a child for so long oddly distant. Giving a snort, he started trotting back towards the outskirts of town and the rest of his party.
The little boy watched the big centaur trot off in awe, and then scrambled up. There was still time to play before it got dark. He giggled and ran off to join the boys and girls in the muddy street.
