"There are many things we do not know about the so-called 'once and future king'. Most mysterious of all: his current whereabouts. As I have laid out, tracking history between dimensions is often quite difficult. While time does move at the same rate between the different worlds, the way it is measured and where the calendar starts can vary drastically," the teacher took a pause to sit down.
Heron Moorsnai was my teacher for the Dimensional Heroes class. A man in his mid-fifties, he had surprisingly good hair and a surprisingly weak spine. He also had a love for passionate gestures. The result was that he strutted up and down the stage, only to collapse into the armchair next to the podium every couple of minutes. Despite relying on a wooden cane during all of that, he never seemed to run out of breath.
"If you ever find yourself studying history, be aware that the library has a Time Compendium. It's always partly inaccurate, but, for most places, it will allow you to find out which dates are parallel to which others. You can't create a proper timeline without it... now where was I..." A moment of silence. "Ah, yes, where Arthur was last is hard to discern. It is either Earth or Marvellia.
"Earth's historical documents from that time are rather primitive and full of holes. In the first place, due to how Earth's god handles things, he is only treated as a local legend. Marvellia went through revolution at the same time and replaced its calendar thrice during that period. The result is a fifty year period of confusion, during which the last sight could have been on either of those two... worlds..."
The last words came out somewhat forced, as Heron fought himself back to his feet and went to the walking part of his steady routine. "The legends between those two worlds are remarkably similar, however. Having fought his son, Mordred, he was mortally wounded and returned to his base of operations in Avalon to heal. As I have told you earlier, although Arthur's tales often mention this Avalon, nobody knows where or even what exactly it is. It could be a place in a world, it could be a world unto itself. Whether he has died there or will yet return, we do not know. Given the time since his last sighting, however, the former is much more likely.
"In summary, King Arthur Pendragon is one of the most famous heroes across dimensions. He sired, directly or indirectly, governments across worlds and always fought on with justice and humour in his heart. While he hasn't carved out any one institution that remains with dimensional travellers to this day, his mark upon history is felt across countless countries, nations and even planets," Heron fixed the collar of his plain shirt and stood straight for a moment. "That concludes this week's lesson. Next week we talk about Nutheus the Core. That should be especially interesting to the slimes and slime lovers among you."
"I do love me some slime girls," I hummed when the 'end of class' buzz all over the room began. Willt and I were throwing our writing utensils into our bags. As was usual, he had taken a lot more notes than I.
"I don't really get that," my longhaired warlock friend answered in a quiet tone, clearly intent on not getting heard.
"Excuse you?" I asked in a playfully offended manner. "What is there not to get about loving slime girls? Their whole body is raw juiciness!"
"I don't know, I don't really like the fact that they're basically all one colour," Willt responded with a shrug. "Plus, translucency is weird."
"Okay, one, your girlfriend can be summarized with the word red...," I pointed out.
"Arlethia isn't just red, but sure, go on," speaking more confidently as the room around us cleared, Willt adjusted his glasses and crossed his lanky arms.
"...two, the translucency is the second... no, third best... no, fourth best part," I kept correcting myself as other things came to mind. "Don't you think it's hot to see your dick penetrating them in real time?"
"No," Willt shrugged and glanced over his shoulder. The only reason why we were still sitting was that we didn't want to get caught up in the cramming that always happened around the doors. "I do like that they can decide where their body is sensitive though. I'm just going to assume that's your favourite thing about them?"
"Well, no, that's number three, actually," I responded and then explained further. "Because, sure, that's hot, but I'm pretty confident I can get them off the normal ways as well. Number two is the whole reshaping bit. Can't argue that having a girlfriend that can take whatever shape you want on any given day is super-hot."
"Really can't," Willt agreed, "Except, you know, it's shape only and the texture is the same. Unless you're talking about a Doppelganger."
"This may be a problem for you, my dearest, demon-obsessed friend," I made a dismissive gesture. "However, for a connoisseur of female beauty such as I, this texture is heaven. For you see, a slime girl is described to be made entirely of a jelly that compares best to the properties of a delicious booty, firm and jiggly. Who am I, to deny the heavenliness of such a creation, made entirely of gropable wonder? Not a fool, I can tell you... unlike you," I pointed directly at his face.
Willt rolled his eyes and slapped my hand away, "If that makes me a fool, alright. What's number one, by the way?"
"They can split. You can have a one-man orgy with any number of perfectly curved girls." Now the same eyes stopped on me with the gravest of expressions surrounding them. "What?" I asked, getting the feeling I wouldn't like what I was about to hear.
"Sorry to break it to you mate," he told me, "but I think you skimmed that paragraph at best. There is exactly one slime species that can do that, they only do it during mating season and to do that they become rooted to one place because their body mass expands rapidly." Willt put a hand on my shoulder and let out a fatherly sigh. "I am sorry to tell you this, buddy, but you can't experience this unless you find one of those and are ready to raise a bunch of oozlings with a woman that will get as big as a house."
I fell silent.
"...I can literally see you consider it," Willt joked.
"One-man orgy," I repeated.
"You're such a simple mind."
