Another Camp?

Xylo is done asking Hades for answers. So he decided the only way to get some answers was to go to the oracle. They then send him on a quest to find his mother.

Every thing was good in Camp Half-blood. The wars are over, the camp was victorious, and all is well. That is until a silhouette flies over camp. What could this mean.

Those who are wondering this happens the day after he goes to the moon, but he never went to see Momiji.
