"This cave will show you your future." Ygraine continued to speak knowing Arthur had to hear all of this and quick, she was breaking more magical laws than should be allowed, but it was her son, her Arthur. She had seen his future, his death and it had come too soon, "it will also show you your past, it will guide you and maybe it will help you." ((Watching the Show Fanfic))
