Ah another wonderful Sunny Day in Ponyville... But who gives a Flying *yay* About Ponyville Anyways! the real action happens in the Everfree! and of course there are two (technically 3) beings brave or stupid enough to live near that CelestAI forsaken hellhole...! No, but really, As we begin this we see something unusual... we see an Unicron Unicorn walking the path towards the Everfree, so... let's be real perverts and let's check the mare out...! this young unicorn has a light cyan mane, with golden eyes and aquamarine coat, on her flanks her cutie mark is a lyre, and, in front of her, levitating on a golden aura, is a map...
"Mmmm, let's see... according to the Map Left is Fluttershy's so right is it!"
And, satisfied with her navigational skills, the mare takes the chosen path, walking all across the border of the Everfree, until is greeted by a house... which would be a non descript 2 stories house, save for the weird design of it... a Wooden sliding fence covering the left side of the behemoth of a home but only half way the building... to the right side a smaller door cut into the frame, but in the same style of the fence appears open, revealing a carriage parked inside, upon entering the little garage, the unicorn sees another door in the right , noticing a stair case built out of the other half of the fence, this one half made of stone, half wood, still, She notices the inner door opened so she decides to knock...
"Hello? is anypony home...?"
Asks the mare as moments later a green ghostly figure appears, of course by now everyone in Ponyville knows the Alicorn that made his home on their town... Yet, nopony had really coped with some of the things the Alicorn brought with him... main about those was the so- called MOS-Tan, Unicorns might try to magically justify it, but everypony knew things didn't have life, no matter how complex were... so, the mare couldn't avoid to be startled as a voice said...
"Ah Miss Heartstrings...! Welcome... To the Castlevania..."
This exchange, of course, ended with a creepy laughter coming from the ghost like appearance of the Alicorn's Assistant, which sent shivers upon the spine of "Miss Heartstrings"... still, the mare knew she had a purpose of being there,and an actual invitation, oddly hoof written by Princess Celestia herself...! (Yes, she checked, pestering Twilight Sparkle until the librarian broke and Acceeded to do the Veracity check spells on the letter....) so the mare just said, in a not so confident voice
"Ah, yes I have an appointment...?"
"Of course Miss Heartstrings... please come on in and take a seat, the Boss will see you soon..."
Politely said the ghostly mare as she vanished, giving Miss Heartstrings time to see the room she was invited to... which it was a living room... tree plush sofas, ranging from a 3 seat to a 1 seat were arranged around a big mirror resting atop a fireplace, above the mirror various pictures of clearly bipedal beings appeared all along the top of the wall, in fact covering all but the one wall, to her right huge windows covered most of the room, providing natural light, while on the left, a book case like piece of furniture was covered with several Knick knacks and one closed door, next to a bigger door on the mirror's wall...
"Do you like it, Miss Heartstrings, or would you rather like I go by using Lyra...?"
Asked a new voice, as the door on the left wall opened, revealing the Alicorn of Ponyville, looking at her curiously ax the mase now known as Lyra Heartstrings spoke...
"Aha! I knew my research back when I was in Canterlot wasn't faulty...! Oh if only those Stuffing Professors saw this! a trove of human things!"
"Oh They have seen it... Old Digger found my decor "Tacky and Tasteless..." then again, They saw ponyfied versions of my stuff, while you, Madame, are seeing them as it... of course I did not glamor the stuff, it's only that only exceptional beings can see through your Universal Mirage... but let me be absolutely clear on one thing Miss Heartstrings... Your theories are, as of March 24th. 2017 completely wacko! Humanity has never existed on this version of a Ponyverse... that is why I look as you see... this Universe forced me to Alicornhood, as a means to reconcile my existence, ignoring and bypassing accords I set with what amount to higher beings... But of course that is not the thing I asked the Princess to get you to me... you see I have a... research... proposal for you..."
