Nyth'ul

You are a demigod at Camp Half-Blood. The Hunters of Artemis have arrived at camp, which means it's time for the traditional game of capture the flag. However, the Camp Half-Blood team is one person short. There is one demigod who isn't present, named Nyth'ul, but the other campers say he either won't show up or they refuse to play or talk with him. You've never seen Nyth'ul before, but maybe you could try to convince him to join the game so Camp Half-Blood won't have to cancel and lose by default to the Hunters of Artemis.
