Five: 3052 AD
My father once said that people are a lot like billiard balls and gas molecules. They collide with one another randomly, imparting unexpected angles of momentum. A secondary impact can cause a tertiary, and so forth. With people it's usually impossible to determine an initiator because human relationships try to ignore the laws of thermodynamics. In the case of the Shadowline, though, we can trace everything to a man called Frog.
My father said Frog was like a screaming cue ball on the break. The people-balls were all on the table. Frog's impact set them flying from bank to bank.
My father never met Frog. It's doubtful that Frog ever heard of my father. So it goes sometimes.
