Stand and speak.

You and your chair part ways with a squeak of its legs against the floor to make room for the presence of the Demon King. "I am Kyle Warren," you introduce yourself formally to all mages who watch. "Labelled as Demon King by King Thadius, a man who has replaced our beautiful Queen Catherine II after she suspiciously fell ill, with nobody else to take the throne either, for reasons unknown. A man who so clearly knew of what was going to happen at the Sports Festival you've all surely heard about."

"So you suspect that the brute who calls himself Demon King, Elok Daven, is in league with the King of Tivera?" asks Okawa as she raises another grape near her lips. "I assume you have evidence to bolster such a claim."

"If it isn't proof enough after the Sports Festival, and the unjust exiling of me to the mountains, then yes. I do have more evidence. But it shouldn't fall me to alone to prove his guilt. As much as I'd love the help of the Circle in taking him out, if you all haven't been observing him, especially since--" You pause for a moment and look over all the eyes on you. "What do you know of how the Sports Festival ended then?"

Lady Sulta raises a hand. "I was there, though in disguise. I saw it all, including the conclusion. The man called Elok Daven spoke of Earth."

"He was powerful, but his body had also changed," you add.

The Chairmen look at one another as the preceding words sink in.

You continue. "I am Kyle Warren, traveller from Earth. And if you want to know more of what I know, I ask for all information the Circle has on Isekai Theory."

"That is certainly ancient knowledge, secret to most," speaks the dwarf, Bulrak.

Barkis turns to him. With his elbows on the table, and with his fingers crossed against his forehead, he appears deep in thought. "That it is. However, Sir Warren here is no average man. From adventurer to knight of Tivera to Demon King, he's living proof of Isekai Theory, with knowledge beyond what we have."

Okawa licks a droplet of grape juice rolling down from the tip of her finger slowly to the tip of her nail before shifting in her seat to appear more attentive--cloud of soft, fluffy tails stirring behind her against the back of the chair. "There were many incidents throughout history, some confirmed and some not, of people or items appearing from another world. After enough time, these documented cases were studied by Abso's most brilliant scholars to deduce that it all came not from different places, but the same, and one far different than our own. It's said that it's entirely possible for this to happen purely by random chance. Holes in space and time, or something along that regard."

With a nod and a long pause after Okawa stops speaking, as if making absolute certain she's finished, Barkis continues. "Yet naturally people have tried to create these holes themselves. It's thought that most successes have been undocumented, just as is the case with yourself, as such studies would be quite dangerous for a multitude of reasons. There's no telling how much of our own history has been directed by the influence of somebody bringing knowledge from Earth. Inventions. Words. Anything. I've heard of certain tales, such as a brilliant tailor of the past being a suspect of Isekai Theory, which is why he was able to create such fascinating designs, and more importantly, create materials that were new to us. There have even been some adventurers from a very long time ago said to have been from another world."

"Elok Daven and his right-hand-woman Breiah dragged me here," you say. "Same with William Cresswell, the Demon King southwest. We were experiments beyond that. Apparently us Earthlings don't have the bodies to have mana or classes or anything, so he altered both of us to remedy that. But his intention, I assume, was to control us both. Though I figure that was only one plan, because neither of us bowing to him hasn't seemed to slow him down. With the technology they have, they could theoretically give anyone a body that could do anything any class could do, or more. They could even possibly open a portal back to Earth. You said you wanted even more proof, Lady Okawa? You all want even more reasons to hate Elok Daven?"

Her piercing eyes stare straight up at you.

Then with a movement of your hand, you gesture to the robed woman adjacent to you.
