1: Odd Beginnings

Will and Nico didn't talk often. They had that small skirmish during that one war, a small argument afterwards, and then they didn't talk to each other again, only interacting when Nico gets hurt and Will has to heal the death child. Now it's years later, Will is 19 and Nico is 18, and some sort of fate force them to interact. For the better or for the worse.
