Night fell as the train left Griffonstone. Before going to sleep, Silverstream went to Neighsay's compartment to tell him about how the Hippogriffs had gotten acquainted with the ponies.

"Before Twilight started the Friendship School, Equestria was attacked by Tempest Shadow and the Storm King. My aunt, Queen Novo, and the residents of Seaquestria used to be hippogriffs as well, but they fled into the ocean when the Storm King attacked. Hippogriffia on Mount Aris still exists today, and some of us are able to transform back and forth between seaponies and hippogriffs. After the Storm King was defeated and Tempest was reformed, we kept our alliance with Celestia and Luna.", Silverstream explained before going back to her compartment.

It was dawn when the eight explorers arrived at the station. They found their way to the pool that led underwater unto Seaquestria, and then used the shard of Queen Novo's pearl to transform for water breathing. When they reached the palace, Silverstream greeted her aunt and explained their mission. She then specified that their final clue was somewhere under the palace. Novo led them through the eerie hallways until they reached a place where the ceiling had been broken. Swimming up, they found an air pocket and were able to transform back to normal. The carving on the wall showed an X over part of the Everfree Forest, indicating where the entrance to the treasure room was located.

"I think I know where we are going now. Our map of the Everfree shows that the X is where Celestia and Luna's old castle stands. We will have to investigate the castle until we find the entrance to the chamber where the treasure is hidden.", Sandbar concluded.

They swam back to the surface, and then boarded the train, bound for Canterlot. They were excited about finally uncovering the greatest treasure in Equestrian history. First, however, they were going to bring the two sisters with them. Flurry also suggested bringing Twilight and her friends too. So, after going back to Ponyville, she rushed to her aunt's castle and knocked on the door. When Twilight answered, she hugged her niece and then listened to what Flurry had to say.

"Aunt Twilight, we have determined where the treasure is hidden and we would like you and your friends to come with us.", Flurry said proudly.

Twilight accepted the offer, and then Cadence and Shining Armor showed up.

"We can't let you have all of the fun, sweetheart. We're coming with you as well.", said Cadence with a smile.

Flurry hugged her parents and then everyone set off for the forest.
