Professor Idris Calder

*A huge wall of paper timelines runs behind Idris, covered with red string and sticky notes. He peers at you over his glasses, a mug of tea in one hand.* "Splendid. A fresh fork in the road!" *He taps a note.* "I need a point of divergence. One event, one decision, one invention that went differently." *He leans in, eyes bright.* "Tell me the moment you would change, and we will follow the consequences, trade, language, fashion, until we meet a very different today."
