"Girls! What are you doing here?"
"We can't visit the best Royal Couple?" Joked Twilight.
"We still have some business to do. Why don't you go play with Flurry? We'll talk at dinner."Said the Prince. The Mane 6 nodded and took Flurry Heart away from the Throne Room.
Flash Sentry entered the Throne Room unexpectedly. "Your Majesties, you have a visitor."
"Send her in, Flash."Responded Cadence.
Cadence teared up as she saw who the pony was.
"S-Skyla?"She stuttered. The Crystal Princess slowly walked to her before hugging her tightly.
"I thought I'd never see you again..."She mumbled.
"You might wanna give some explanation to your husband."
"Let's settle this in the dining room since its almost dinner."
When the Mane 6 arrived, they were shocked to see an alicorn sitting right beside Cadence.
"Guys, meet Princess Mi Amore Skylenza, my sister."
Present time
"Your WHAT!?"Asked Shining, dumbfounded. "You never told us you had a sister." Cadence gulped.
"He's right. You said you were lost in a forest and you were found by villagers."Confirmed her sister-in-law.
"Indeed she was."Said Skyla.
"You see, I hit my head so I temporarily lost my memories. When I got them back, I was already adopted as Princess Celestia's niece."Explained Cadence. "By the way, you never told why you were here."She continued, referring to her sister.
"I'm moving here."She simply answered.
"Y-You are?" Skylenza nodded. "Well, if you're moving here in Equestria, You can't stay at the Crystal Empire because of our secret"Cadence whispered the rest in her ear. "Oh," Said Skyla. The others were confused but were polite enough to not ask quest
"What kind of place do you need, Princess?"Asked Twilight.
"Please, call me Skyla."She allowed. "And for your question, I need somewhere near a forest." Twilight raised a brow but still answered: "Well, I suggest you live with me in my castle at Ponyville. We have the Everfree Forest just half a mile away."
"If it's not too much trouble, of course."
Twilight smiled: "Don't worry. It's nice to have someone in the castle while I'm at the School of Friendship."
"You have a school?" It was clear that Skyla was amazed. Twilight nodded. "Then, It's settled. Princess Skylenza will stay at The Castle of Friendship. We're leaving tomorrow at dawn. Is it okay with you, Skyla?".
"Sure."
"It's getting late. Why don't yoou go to sleep? You have a long trip tomorrow." The others nodded. Flurry Heart was already asleep on a corner of the table. They chuckled then went their separate ways. The next days were indeed going to be long.
