Without memories nor past

I woke up with a slight headache in the middle of what seemed like a public place of a rather rich city. Ponies were walking by, some of them were shooting me pitiful or even disgusted looks, but I was way too lost to pay attention to them.

'Where am I ?' Without turning my head I glared at something what looked like a castle, but much taller, 'This thing is huge...' I turned my head to see a plain followed by a dark, almost unnatural forest.'I am pretty high up in altitude, if I can see that far, but I still don't knowwhere I am...' then another realisation hit me, much more shocking: '... or who I am...'

"Excuse me ? I'm lost, but that's the least of my problems..." I asked a white pegasus stallion with blue tail and probably mane, though I couldn't see it because of the armour he was wearing. He was standing at the gates to the enormous building. "I can only advise tourists to visit somewhere else, or go to a nearby guard office to get your questions answered" he said without even budging. "I am not a tourist, but  thank you..." - 'That was interesting all right' - "But where can I find the 'nearby guard office' you were talking about ?" I asked still perplexed by his behaviour. "You can find the nearest guard office down this street and then left" he responded like a machine programmed to answer this kind of questions. 'This guy is weird...'

The guard office wasn't hard to find, but it took about five minutes for me to get there, since I was a pretty slow walker at the time. 

The office was a large white building with a sign saying "Royal Guard-Public Affairs Office". I went in.

Inside, there were a few ponies talking to guards, others waiting for their turn. My attention turned to a white unicorn mare taller than everypony else in the room who entered the room right after me. After a short while I realised she had a pair of wings too. 'She has wings and a horn ? I would be jealous if I didn't have bigger problems at the moment...' Her rainbow mane was flowing freely as if it consisted of something as light as air, or even lighter. As she entered the room everypony froze, except for one pink pony who was still loud: “And then I said: Oatmeal ?! are you craz-” she realised she was the last one still speaking “whoopsie doopsie, sorry” she immediately apologized.

Then my moment of awkwardness came, after I realised I was still standing when everypony else was already bowing to the alicorn who had just grabbed my attention. 'Who is she ? Should I bow ? I don't want to bow to somepony I don't even know...Bow ? Don't bow ? That is the question...' I slapped my intern self for such silliness. 'I don't even know why it seems like a joke to me, I feel like it's some sort of inside joke, but I can't quite put my hoof on it...'. By the time I came out of my thoughts ponies were already shooting  dirty looks at me, finally one of the guard ponies yelled at his subordinates: “Arrest him ! Arrest the disrespectful pig !”

Before I could react to what I was hearing, the tall white mare interrupted them: “Let him, I'll take care of him,” she turned to me, “if you would please follow me into that office over there.” She nodded towards a door.

At first I was hesitant, then I realised it was that or getting arrested, and that didn't seem very comfortable.

We went in the small room, which was slightly less lit than the rest of the building.

“How much do you remember ?”

“Well, noth- Wait ! Why did you ask me that ?  How do you know I have amnesia !?”

“I saw that confused look on your face when I stepped in, and I know none of my subjects would have refused to bow. Except if he didn't know who I am, in this case I can assume he either lost his memories, or is from really far away. I decided to ask you about the first possibility. And you just proved me right.”

“Oh, now it makes sense...”

“Do you have a piece of identity in whatever kind on you ? I doubt it but I want to make sure”

“No, I don't think so, but lemme see... No, nothing it seems...” I said looking for saddlebags where such thing could have been stored.

“Well, the best would be to take you to a hospital, to check your medical condition, you don't seem injured, but just to make sure, then we'll be closer to know why you have amnesia. The next 'hospital' isn't technically a hospital, but it's got all of the required equipment. It's the medical wing of my castle.”

“Your castle ? Right you seemed pretty important back in the other room... May I ask who you are ? If you don't mind, that is.”

“No, of course not, I’m princess Celestia of Equestria !”

“Princess ? Who's the king ?”

“We don't have one. We'll discuss that on the way, shall we ?”

I simply nodded. We made our way out of the building and started walking towards the castle I had noticed at my awakening.

“So, as I was saying, I’m a princess, but we don't have a king nor a queen.”

“So you are the highest authority here if I got it right ? Now I know why all these ponies were bowing to you back inside. Should I bow now ? You know, 'cause I didn't bow before.”

“No need for this. If you don't like it, don't. Ponies always bow naturally to me, they seem to mistake me for some sort of tyrant. Even the guards think they should arrest ponies who don't bow to me... All because I sent my sister to the moon 1012 years ago...” Her voice took a regretful note at the end of her sentence. At the time I was too shocked by the fact that she had bannished my her sister to the moon to realise the high number of years she stated.

“You've sent your sister to the moon ?! How are you that powerful ?!” I asked shocked.

Her facial expression suddenly changed to worried as she realised she had probably said too much. “I used the elements of harmony; she had turned evil and wanted to plunge Equestria into eternal night. But now she has been reasoned by the same elements of harmony wielded by other ponies upon breaking out of her lunar prison. I will explain in more details later, if we have time, of course. Oh, look, we are here. I'll lead you to the medical wing, and then leave you there, it's near the main entrance for easy access in case of emergency.”

“But the guards don't let you pass...”

“In case of a real emergency they do, if they have a proof that the injured pony is in a life threatening case, to avoid tourists just simulating injuries to get a visit of the castle. But most ponies don't even know there is a medical wing in the castle, so they go to the other hospital in Canterlot.”

“But the guard was so cold and inflexible... It was like he wouldn't let anypony in, no matter what.”

“A guard must choose between two types of armour, one is normal, the other is enchanted to help them hide their personal opinion and feelings. Most of the guards choose the latter, because it helps them doing their job...”

“Oh” I didn't really understand why it would help them in being a guard.

“A guard mustn't move from his position unless told so or his shift is over, and he must always be ready for action. The enchantment helps them concentrate.” 'Is she reading my  mind ?!'

We had arrived at the little hospital inside the castle several minutes ago, but had stopped right there to finish our conversation without realising we were already there.

Celestia approached the only doctor pony in the room. “This pony here has no memories, I would like you to find out the reason to his amnesia. Do all the necessary tests. When you're done, send me a letter through the pipe system.”

“Of course your highness.” He said with a bow. The white mare exited the room.

“Let's get started, shall we ? I need you to got lie on that bed right there.”

/* Author's note: So, there goes nothing, it's the first chapter (duh!) of my first fanfic, if you are confused about one part, or have found a spelling/grammar mistake, please tell me in the comments. Also, criticism is much appreciated.

This story will be the first part of a 'trilogy', I don't know if I should call it a trilogy, since the first two parts will have a common sequel which will be the 3rd part

And, if some parts seem random, or useless for the story, they probably aren't, I'm just trying to make a story with a more or less logic storyline (some stuff that may indicate some personality disorders, a detail about his amnesia, etc.) but tell me anyway, because better safe than sorry, right ? right ? :D */
