You walk down the town square in 1300s Italy. You pass by food stalls, stables, shops, beggars, and pestilence carrying rats. You dodge some careless soldier riding a black and white horse coming straight at you.

Then you see what looks to be a young man, high up, standing on a beam. He jumps, spreading his arms like a bird would spread its wings, then he lands in a pile of hay. He rolls out of the hay, now standing in front of you, studying you.
