Mushi's classroom of mythology and potential ancient history

Class introduction

Around a library in one of the many vaults of the Academy known as beacon we see an individual who sits listening to music box, whatever this tune means or it connection to the individual in question is only known by two people and we're seeing the first and the second is long gone from the plane of the living.
This individual is Mushi Muyoku Akuma the vice principal of Beacon academy and the right hand of Ozpin, yet unknown to most other then Ozpin's innermost circle and the creatures that were around the time that he is part of one of the most dangerous dark species of all creation, a demon and a high ranking one as well that had pension for violence and slaughter but those days are long behind him now helps maintain balance with Ozpin and Salem (this will be explained)
Mushi's POV
'To think that I'd be a teacher, that is irony if I've known it but I suppose Ozma needed someone to help him at some point and to think that Leon's academy is where I'll be working, it's certainly changed over these centuries, even Vlad would be remiss to not complement the architecture that Leon placed as a foundation for the future generations to improve on'
I'm suddenly removed from my thoughts as i hear footsteps behind me and i see Glynda Goodwitch, my fellow colleague and the combat instructor and when I'm away on a mission my replacement as vice principal of beacon, I've seen many people of her calibre in the arts of magic, but she comes closes to the old style of it, after the Twin Gods unleashed their wrath upon the I haven't seen many magicians actually show the amount of power and skill she has other then Merlin but she's a special case with who her family are and outside of the territory that would make the kingdoms that were protected by the Draconian Lords magic is something of a rarity in and of itself so she's a gem without a doubt.
"Glynda is there a problem or are looking for a spar you'll have to go easy on this old man my bones aren't as flexible as they once were" i questioned her with a friendly elderly smile i may not look that old maybe my forties at most but in reality i got see the creation humanity along with many of the species that inhabit this remnant of a world
"Mushi, if I wanted a battle I'd have attacked you the moment I entered just to have the hope of landing the first strike not that it'd be much of a chance you probably heard the elevator coming down from here from miles away, but alas I've come to inform you that your class should be starting soon and you should start making you're way to your classroom."
She's not wrong even all the way here I could still hear the elevator coming from the upper floors, but alas that doesn't really matter right now I need to get to the classroom, oh well I guess that I have to use my most useful ability teleportation, I begin to dissolve into mist, as is begins I look towards Glynda and remark "I'll see you after class then Glynda, you know this should be fun" and then I fully turn to mist and leave Glynda behind.
"That man, why must he act like there's nothing wrong yet he has this inner sadness that just radiates around himself, but he doesn't confide in anyone but Ozpin" she sighed with a heavy heart.
At the classroom
Reforming myself I beat any students and begin to set my lesson up, it didn't take long to do as I've been preparing the current curriculum for the year since the first half and I already have set the topics all I've got to do is establish myself with the students so all I have to introduce them to the topics we'll be viewing and understanding, a couple dozen minutes latter I heard the bell tolled allowing me to know that the students are going to arrive soon so i sit down and open up one of my one of my favourite novels a great retelling of the wizard and the girl in the tower, a story I was there to witness and was one of the main sub-characters although I certainly have to admit that the author definitely altered what I was like back then compared to the story I'm reading, but i suppose that's the thing about myths and stories is that the people of that time aren't meant to see their own story near millennia after it happened, I hear the door open and the last team to come in is here I look at them and see that it's team RWBY.
with an expatriated sigh I begin to write upon the board 'welcome to studies of legends, ancient history and pre Kingdoms history'
" now that everyone is here allow me to stand on ceremony and introduce myself , I am Mushi Akuma and I am the vice-principal of Beacon academy and as you can see on the board behind me that is what i shall be teaching you until your time here is over, my mission is to allow you to understand and theorise about the ancient times of man and remnant, as well as history of the kingdoms up to the Great War, you will be silent until i allow for you to ask questions otherwise if something catches your attention or if you wish to have something " his voice boomed through the classroom, the students could do little but nod their heads to Mushi's demands "good, shall we begin with what is seen as the era of myth can any of you tell me what it is, what it represented, when did it begin and what led it to it's end, you may discuss with your teams or friends" he spoke with a gentle voice compared to his early demand, yet it still held a commanding tone about it, it amazed the students at the fact of this change in tone and reassured some and steeled others.
The students whispered amongst themselves many wandering where to start that era was long and many points could be seen as the start with only the end being certain, after a while the leaders of Team RWBY and Team JNPR raised their hands to answer the question "aw miss Rose what is your answer" Mushi asked with an intrigued look aimed towards the young maiden "The era of myth began after the Great War of calamity with the creation of the race of man as the validation of the peace. It was and era of heroes as many of our stories come from that era the most famed being the princess of the tower and the saga of the great wizard that tells of the party after saving the princess, it repressed the greatest point for humanity and the other races but in the end human greed made it so that we reached too far and was struck for our transgressions" Ruby spoke with an iron will compared to those who had taken his class in previous years, Mushi the turned to Jaune giving the young boy an icy glare but if one were to look towards where Mushi was glaring they would find a necklace of a proud lion around the boy's neck 'so i see you still show your loyalty towards Arthur, Sole'"what is your answer Arc" the Arc boy gulped at the frozen look he got from the teacher " much like Ruby said it was an era of heroes, but I'd say it was just as much an era of tragedies even the princess of the tower was a tragic character locked away because her family feared her powers, her lover fell heroically but by a simply plague, that very party breaking apart, people being tricked or tainted, such as the Mighty Sole who was tricked to kill a fellow angel who looked up to him or of the nameless warrior of dark who abandoned his humanity to fight  evil only to become so evil that he joined the Ten Commandments" Mushi looked around and saw many nodding their heads and smiled " what these two have stated is completely true, many of the very machines we use came from their time, the Cross Continental Transmit System is a basic version of what the people of that very era had that we can only imitate, but we are stuck in the Remeants of those heroes and people, only the creatures of old such as arch-vile demons or arch-angels or other long living being of light and dark that can truly reveal what those times were like or the vast tombs or archeological sites show us the scope of which our ancestors lived theirs was an era of gods, demigods and the great and mighty dragon lords, sadly the brothers and their fellow deities have long since left, the demigods have long since died leaving  few bloodlines being descended from them, and the mighty dragon lords have long since died and their bones used as the the borders of the great capital city of Ylisstol of Ylisse, the shrouded capital Plegia of the Grimleal caliphate south of Vaccuo, the large castle and city the beaming heart of Zofia and the rigid and harsh icy capital Rigel of Duma's imperial control" he let what he had stated to the students soak into the information he shared to them "but they got the date wrong the age of myth began the moment the draconian lords and the first dragons were created by the brethren deities while the other deities created the very earth you stand on and inhabit, at leat that how the nation's of that era saw dated the events even the pantheon is still shrouded in mystery as deities change or there are two gods who are put together either as married or as one being we don't quite understand what was happening for the pantheon of deities the only constant for the deities we have is that the brethren gods Palaiotero and Pioneos and the princess in the tower along with Archontas ton Theon appear to be the only ones that weren't being changed in each nation." Once again he let the words he had got old the class hang in the air, he saw looks of confusion but also wonder at the era and the fact that beings of such power walk amongst humanity seemed to really bring out the wonder in the eyes of the students "to have witnessed these events would be glorious, to witness the creation of the races we know still exists and the fact that many of the great leaders who have been around for millennia have spoken of these times and the evidence we found stands around us and the ancient ruins of great cities have shown us that this happened, the problem we have found is trying to understand what was exaggerated and cleaned up for children like all legends are generations after they happened and as they pass from person after person after the wrath of the brethren gods was unleashed and everything that we had built and created was destroyed, big proof of this is the fact compared to the draconian kingdoms magic has effectively died off with only a handful of families that still exists..." Mushi's voice was cut off by the ring of the school bell "'sigh' well this is a good point to end, by next lesson I expect to have gotten a copy of Lord Leon Hellsing Belmont's book from the Libary,  he created that book so that future generation of humanities defenders would have the great knowledge of the enemies you will be fighting in the dark as well as the allies of light that can gift you aid throughout your work, as not only humans can be hunters and huntresses, well what are you waiting for dismissed"
