Sole Survivor (A Percy Jackson x Undertale Fanfiction)

Sans had finally killed the human.

He doesn't know why, but they just stopped coming back. He took their soul and, using the other 6 human souls, broke the barrier. Along his way to find a place to stay, he comes across Camp Half-Blood, and there he meets an old friend/enemy who's willing to take him in.

His appearance, though, had caused a whole new threat to emerge. One that could mean the demise of Camp Half-Blood and possibly the gods themselves.
