"Ah!"
Spike had just woken up that morning and saw Tenebris for the first time, since he had arrived at Twilight's relatively late at night
"Wh-who are you?"
"Hmm?" Tenebris was a little surprised at looking up from his book to see a baby dragon
"Are you new in Ponyville or something?"
"You could say that." Tenebris said
"So, uh..." Spike began
"Tenebris" The gray stallion said
"so, Tenebris... you said you just came here, where did you come from?"
"... I don't think I can tell you that much..."
"What?"
"I don't find it relevant"
"If you say so... by the way, the name's Spike"
"Well, good morning to you then, Spike."
"By the way, where's Twilight?"
"She went to Canterlot Archives to rent a few books not found here."
"What a surprise..." Spike said sarcastically "...huh? What's this?"
Spike had noticed the note that Twilight had written before she left
"I should probably send this to Celestia."
"What?"
"Twilight often leaves notes for me to send when she goes places, She's studying under her teaching and has to report what she learns every now and then."
"..."
Spike lit the paper and watched it's ashes be swept away by the wind

By the time Twilight had arrived at the library, Celestia had already gotten the letter and was waiting for her to arrive at Canterlot archives
"Greetings my student."
"Celestia, what are you doing here?"
"I received your letter, and I don't know exactly what to think... You said his cutie marks don't match? Are you sure?""Yeah, I'm sure, I've never seen anything like it before."
"Neither has any other pony for over a thousand years..."
"You mean this actually has happened before?"
"Well... yes, but the way I see it their are two things that could be happening."
"Well, it just so happens that I was looking for answers here. So what are your ideas?"
"Prepare yourself, Twilight, for neither of them are very good."
"What do you mean?"
"The first possibility is that he could be a changeling."
"I never really thought of that... but I've never even seen a pony with an opal mane, changelings usually take the form of loved ones, right?"
"The second possibility is that he's an imitar."
"A what?"
"An imitar is a pony who denies their true self and lives an imitation."
"What do you mean?"
"When a pony gets their cutie mark, it's because they figure out who they are."
"I already knew that. But what does that have to do with someone being an imi... whatever?"
"Well say that somepony doesn't like who they really are, they know perfectly well what they're supposed to be, but they don't really want to be that kind of pony. So they and hide who they are and imitate something different."
"But that doesn't make sense, everypony's cutie mark is who they are, what they like, why would you not like what you like?"
"I don't know, but the fact that he won't give you any information other than his name makes me think that he may be an imitar... most ponies have forgotten about the existence of them. Another sign of somepony being an imitar is their cutie mark disappearing like you said."
"I can't believe something like that exists..."
"Twilight, did he ever tell you what he was looking for in those books?"
"Yes... The "Alicorn Alliance""
"The Alicorn Alliance? they haven't been heard from since Luna was banished to the moon!"
"Excuse me, princess... but what was the Alicorn Alliance?"
"My rule hasn't always gone un-challenged, Twilight..."
"What do you mean?"
"Shortly after I was forced to send Luna to the moon, a rebellion took place among the other ponies, led by 2 Alicorns, their names were "Fosca" and "Umbrus". They thought that I had banished my sister because I didn't want another alicorn compromising my seat on the throne. They knew that Luna had been corrupted, but they thought that banishment to the moon forever was too harsh. Keep in mind that she wasn't supposed to escape, and the only reason she did was because the very stars themselves came to her aid."
"So what did they do?"
"Many of them thought that since I sent Luna to the moon without attempting to compromise, and that I only used her corruption as an excuse to obtain total control over Equestria. So they decided that they would form their own society. Many ponies agreed with this, they set off into the Everfree forest, and haven't been heard from since. I tried to convince them not to go, but Fosca, Umbrus, and their followers left anyway... I have no idea what could have happened to them all."
"But why doesn't anypony remember any of this?"
"A thousand years is a long time, Twilight. Only alicorns and some unicorns live that long. Most ponies have forgotten about Canterlot's hidden gem labrynth that Queen Chrysalis trapped you in also, so it's to be expected that they would forget about the alicorn alliance too."
"Wow... I don't know what to say... But thank you Princess, I don't know how long it would take to find a book with that kind of information... However I still promised Tenebris to bring him back a book."
"I can show you where to find a book with that kind of information... But I want you to try to talk to Tenebris. I need you to at least try to get him to bring the other ponies of the alicorn alliance back if their are any other than him."
"You have my word, Princess."
