Camp Half-Blood

you're coming back from a quest that took 3 years (or however long u want it to have been.), and you decide to play a prank on the others but hiding in a tree at the edge of the forest surrounding the training field and watch them training. Nico notices something or someone/you in the trees, because you accidentally made a loud sound by snapping a tree branch on accident. add whatever. i don't care if you add new people or give one of the characters a new sibling. The ships are the same except for Leo and calypso bc I hate calypso and Leo could do so much better. You can be anything or anyone(its not like I can stop you anyway) the voice was random. I got this idea from another talkie but I can't find it so I made this one.
