Sleepless in Saddle Arabia

Twilight laid and watched her photo album the night after the Canterlot wedding, where she and her friends had saved Equestria from the Changelings army.

"To think that two years had passed since I went to Ponyville, and how young we had been at Pinkie Pie and Gummy's Birthday party." Twilight told herself.

Two years before the wedding Twilight had woken up one early and sunny summer morning after Pinkie Pie and Gummy's Birthday in Sweet Apple Acres. "For decades ago the Crystal ponies had been found in a Crysta Empire, as they had a whole city in the north." Twilight read.

At that time had Twilight thought that the Crystal Empire only had been found in filly story books.
