>Luna paced back and forth, frantically speaking to herself.

>Celestia yawned as the strolled into the royal chambers.

>"Luna, what's got you so riled up?"

>Luna stopped her pacing to look at Celestia.

>"It's been over half a week without hearing anything back from him, dearest sister. What is something happened to him?"

>Celestia chuckled.

>"Luna, I'm sure you're over reacting... I doubt he found the Changelings. I mean, they DID get blasted pretty far out after the wedding..."

>Celestia took her seat on the large throne before using her magic to habitually raise the sun.

>Luna lowered the moon.

>"Yes, but that was months ago, sister. There has been more than ample time for them to make a new established nest."

>Celestia tapped her chin with a hoof.

>"Maybe that book had given him an idea..."

>Luna's ears perked up.

>"Book? Again with this... Book. What was inside of it, anyhow?"

>Luna looked a bit curious, but mostly distraught.

>"It was a book about the known history of Changelings... All the tests we did, observations... Everything."

>Celestia paused to look out a window.

>"All information on them, up to date."

>"And you just LEFT it in the Library!?"

>Luna was steaming from anger.

>"There are so many books in there, dear Luna. How would I have known that someone would have spotted it?"

>"You left the key with the book."

>Luna looked at her sister scornfully.

>Celestia sighed. "Maybe Twilight and her friends know something that could help..."

>Luna gave a yawn.

>"We had best contact them as soon as we can... Who knows what kind of dangers lurk within the ranks of the Changelings."

>Celestia magically poofed in her supplies for the letter.

>"Dear Princess Twilight..."

>Twilight and co. burst through the front doors of the royal chamber.

>"We came as fast as we could, Princess!"

>Celestia looked at the mane six with a solemn expression.

>"Did you bring the book?"

>Twilight levitated her copy of the research files out of her saddlebag.

>"It's right here... Why do you need it? Did the other copy get lost?"

>Luna shook her head.

>"No, Twilight... It might be something far worse."

>"Say, where's that Anon at? Shouldn't he be here with you?"

>Twilight tilted her head some.

>"That's the thing..."
