This is my second fic that follows the events of Kingdom Hearts: Ponies. It would be recommended to read that one first but I have tried to explain past events in this one. So anyways, Sora, Riku, and Axel head right back to Master Yen Sid's Mysterious Tower to tell him about The Dimension Between Worlds encounter. What Yen Sid will say will probably relate back to darkness or light, as most Kingdom Hearts related things do.
