I'm just talking to myself here but I don't know if you'd notice if I edited an old post, so I need to make a new one. 
A few small alterations of the previous lore include: 

1. Lily Quarin goes back to the original Lily Quann.
2. Hell hosts way more than four lords, the kingdoms and tribes being more numerous than before
3. The things Szayeis and Darius did for the Academy (and in regards to the incident between Maroon, Lily, Szayeis and Hazumi) are now Ein's. It's a rather quick write-up on who he is, but with the little time I have, this is the best I can do right now. As I don't expect him to have much to do with the other characters, I don't see a problem with keeping it simple but if you want some more extensive info, let me know and I'll try.

The Academy’s new headmaster is called Valaniein Tanirea Manis Karelisa or just Ein for short. He was a lord back in Hell but stepped away when the Surface became accessible, in order to seek new knowledge and a fresh perspective, He first came to the Surface a little over 200 years ago and has been involved with Master Melody’s ever since. He was there to help with the communication between Lily Quann and Hazumi when the Academy’s functions were changed at the end of Judas’ war, and he was there to take over when the previous headmaster resigned her position after the Illuminati assault. 

Ein isn’t overly ambitious so he never tried too hard to achieve a status in Hell but a few hundred years spent as an incubus have changed his perspective and made him long for more. He worked on his evolution quietly, pleasing everyone who’d venture into his lair and hunting with the other incubuses until he eventually accumulated enough essence to get out of that cave and the lifestyle. His most recent incarnation is that of a draconic being that looks almost human save for a few key features. He is taller than most men, standing at just over two meters, and has a strong but lean figure that’s usually clad in some regal looking attire. His whole body and most of his face is covered by tough  dark blue scales that look black in artificial light and are more than capable of repelling a bullet. Next up are his weapons - aside from the talong on his fingertips, Ein has a strong reptilian tail covered in spines that he uses in a variety of situations as easily as he’d use his hands, if not more. And lastly, levitating over the thigh-length red hair is an ever-present flame that looks like a halo to most. It spins over his head and seems to reflect his moods without him even realising. Ein’s character is rather mild and diplomatic but one shouldn’t be fooled by the good manners - his body is a very fine weapon and one would be foolish to underestimate that. [/hider]
