I knew that the strange immortal I knew only as the worker would be almost certain to fight for the Ottomans again. But I also knew that he’d know I’d know that, and would avoid somewhere so obvious as Constantinople.
I needed to search for him elsewhere. I made my way back from China, and became a preacher by the name of Giovanni da Capistrano. I undertook missions for the popes and searched for the Worker in Milan and Burgundy, while ostensibly opposing the Antipope. It was but a ruse as I searched for my nemesis. Eventually, news came that Constantinople had fallen. I made sure that I would be well placed to find him. I responded to Pope Callixtus’ call for a Crusade, raised an army of peasants and marched to the aid of Belgrade.
The castle of Belgrade held us safe for a while, but eventually the Ottomans breached the falls. My peasant army rushed to fight, and I followed them onto the field.
I saw Mehmed enter the fighting, but then he took an arrow to the knee.
At the next moment, I heard a cry, and there he was - the stranger with the plank of wood.
Again, I tried to engage him in conversation, and again he refused. I fought more calmly this time, and although I again had the upper hand throughout the battle, the fates smiled on my adversary and his unusually defensive style, and luck saw him survive, again. We fought all day, and were ordered back behind the walls at dusk. When we came back out at dawn, the Ottomans, and The Worker were gone.
This identity used up, I used the convenient excuse of the plague to fake my death and moved on through the years. Maybe next century we’d meet and finish this.
