Sherem walked the streets of canterlot, and feeling what he would call an "itch" because he was not on duty and was doing no work and too add it was also an awkward situation, for it's not common for the ponies of Canterlot see an alicorn to have a casual stroll, least of all Sherem in no armor, therefore he attracted a lot of gazes and stares from everypony around.
He went into the store that sold boxes of Cider and decided to take 3 boxes packed with bottles of apple cider, the alcoholic kind, and then remembered that a possible reply could have come from Advisor midnight in his Exchange program and again the voice inside him said "don't get your hopes up wussy, you're not that interesting of a pony, on the other hoof if it was me who we were talking about..." and got interrupted by sherem speaking in a low tone "nopony asked your opinion" he checked his mail locker and found the letter and read it. Giving a sigh because he felt two matters uncomfortable, speaking about the glyphs and his ascension, but he could at least try to answer one of them.
Then as he returned his place, he got to write the letter, but as the first drop of ink went onto the parchment he felt losing control and out loud he said with a different voice and his eyes turning sharp, replacing the yellow and black the other entity inside his head took control and said "now now, let's make this more interesting" and suddenly shifted back to his old self and said "NO! no no no, you can't and I will not allow it" his other self replied "Seems you still have some strength, but trust me It won't be long before I start sending MY letters, wussy" he mocked him and laughed.
Shaking his head he started to write down the letter.
Greetings again Advisor Midnight
First allow me to express my joy to see that you got my letter and decided to write back, I cannot thank you enough for your time though I ignore what are your duties and your position exactly. I would ask questions of my own soon enough about your own post.
But first let me try and give a reply to most of your questions.
First about the chain of command, well you are partially right since commander Shining Armor is no longer the head of the Solar guard and was replaced, he is the higher military authority in all of equestria. Most reports of all the guards around the domains of the princesses go to him all the way to the crystal empire, my birth home, and yes I serve as a second in case the captain is absent and other stuff witch by protocol I cannot detail here.
About of how I became an Alicorn...well, I was born as a pegasus first and by the grace of Princess Amore and my merits in the matter of Strategy and Planning I was ascended to Alicorn, by Celestia and Luna It was hard to do magic at first, it was a...difficult process very very difficult. I do hope this brief answer would go well for your curiosity.
As for the glyphs surrounding my Cutie Mark, I'm afraid I cannot give you an answer because...it is a delicate matter, very delicate and perhaps and also maybe, it's a big MAYBE, I will convey that matter one day, but I see that a bit far away.
As for my questions I will try not to pry too much into personal matter, see which ones of these you will answer at your leisure.
I never heard of your position or what is exactly what you actually do, does it have any links to the royalty? Who are the Children of the Moon? and Finally how did you lived around 1020 if you are earth pony but with no horn and wings?
I do hope you find this letter your liking .
~Sherem, Vice Captain of the Guard
He sent the letter via the official line of the program and then decided to "Bend" the rules and accords of his "Time off" and visited the forges of the guard, where he decided to act as a Volunteer around the forges, even if it meant to carry heavy bags of ores and coal.
