"The Dragon That Changed Everything" Rimuru X OC Character

An: this chapter is from a small discussion with RayhanrizkyrRayhanri about the side story of Clayman's revenge. So this chapter will have some spoilers for the first few chapters of that side story and for this story. An end.

Fourty-eight years before Rimaru was born within Erogon's seal he was resting peacefully waiting as he felt time distort within the world.
"What was that?" Said Erogon opening one of his eyes and peered into an observation orb towards the source of the disturbance and saw it was in the kingdom of Jistav. "Wait isn't this Clayman's domain." As he ignored the distortion but felt it a second time within seconds of the first, which angered him.

"What the fuck," said Erogon turning into his human form as he opened a portal to Jistav, "who ever is doing that is going to be punished!" As he went through as he cut his powers in half leaving it in the seal.

Within Clayman's castle, "so you're telling me that you got killed twice by a slime?" Said Laplace laughing his head off. With Clayman depressed across from him on a couch.
"Yes," said Clayman, "but I think I got caught in a time loop and this is my last chance."
As Laplace stoped laughing, "that makes sense, but your second time you waisted."
"Hey i didn't realize what was happening till it was too late!" Said Clayman, "but there was a difference between the two."
"What do you mean my lord?" Said a dark elf maid that was in the room.
"The number of people there Eva," said Clayman, "the first time was just the demon lords and the storm dragon, but the second time is was the demon lords the storm dragon and the observer was there with five other people."
"So there was a difference even though you did nothing?!" Said Laplace sitting up quickly an Clayman nodded then Laplace pondered the info.
"So someone influenced the events in the second time that wasn't Clayman?" Said Eva.
As Laplace continued to ponder. Who would be strong enough to alter history without remembering the past events? As something dawned on him. "Wait, Clayman who is the observer?"
"Oh it was Erogon Wolfsbaine." Said Clayman which shocked Laplace.
"Wait are you serious!!" Said Laplace standing up quickly in which Clayman just nodded.
"Wait who is this Erogon person?" Said Eva.
"It's not a who more of a what," said Laplace, "he is one of eight true dragons in the world!"
"Wait eight?" Said Clayman, "I thought there was only four?" Which got odd expressions from both Laplace and Eva.
"What if the first time was actually vastly different from the second time?" Said Eva.
"Care to elaborate?" Said Clayman.
"Well let's take the two Walpergis you died in, there as more people the second time around," said Eva, "so some time before that, someone greatly altered the world in it's entirety."
"It makes sense," said Laplace, "from our memory there are eight true dragon but you remember only four." As he pointed at Clayman.
"You're right," said Clayman, "do you know of anyone that would have that sort of power?"

As Clayman finally words came out of his mouth all three of them sensed a bone chilling aura as the room there in became isolated from the rest of the world.
"What the hell!" Said Clayman looking around as Eva got in front of him from the window as a figure cloaked in shadows.
I recognized that aura! Thought Laplace as he got into a combat stance. "I thought you were trapped in that seal Erogon." As Clayman saw the shadow formed to show Erogon's human form.
"Hehehe," said Erogon eyeing Clayman with his real eyes, "I felt a distortion in time that would ruin my plans so I came to fix it. So regressor that's why."
"EVA!!" Shouted Laplace as he charged at Erogon. As Eva grabbed Clayman's color and started to bolt for the door but all three were stopped by thin orange threads.
"Demon marionette." Said Erogon as the threads were formed from his left hand's fingers. "You recognize this technique don't you?" As he started to walk towards Clayman.
Damn it, damn it! Why, why did this happen, wait! Thought Clayman, "I want to know something before you kill me."
"Oh," said Erogon smiling, "you think I'm going to kill you, that is a surprise." As he put his hand on Clayman's shoulder.
"Wait you're not going to kill me?" Said Clayman.
"Why would I do that," said Erogon which surprised all three of them, "I need you alive for my seal to be released. So I'm just going to make you forget about this encounter and your loops." As his other hand covered Clayman's face.

Notice use skill Fate Weaver?
Y/N

Yes, thought Erogon as his skill activated and altered Clayman's very soul forcing him to forget about his regression and what happened in the last two timelines which also altered Laplace's and Eva's memory of what Clayman told them.
Notice total people within the archive of time: 2
Good, now realize and understand how you fell Clayman. As Erogon left as the isolation barrier dispersed and time returned to the proper order. Now my plan is back on track.

As I returned to my sealed cave to rest Rosealene appeared beside me. "Master was that necessary?"
"Explain." Said Erogon.
"Well Clayman could have remembered what happened, but we could have framed him instead." Said Rosealene.
"We could but," said Erogon, "my goal is to be an ally of that slime if the frame job was tied to one of my subordinates it would mean I ordered it, and besides he still remembers." As he pointed to his head.
Rosealene went wide eyed as she realized what you did, "I see you are quite the manipulative master."
"At least I will keep my promise." Said Erogon turning into his dragon form and going back to sleep.
"Enjoy your recovery and rest master." Said Rosealene as she vanished.

Clayman opened his eyes and saw white, as he looked around he saw the floor and ceiling was white but the walls were covered in books "where am I?"
"I see I have a new guest here." Said a woman with black hair with two buns and verdant eyes. She wears a pair of glasses and keeps her full figured concealed by black dress lined with red fur and wears black gloves on both of her hands. The dress also possesses a long slit cut out for her leg which reveals knee length black and white vertically stripped knee socks. A large knot with white stripes is present below her large cleavage that joins the red fur and the slit cut out for her legs. She wears a pair of circular, palm-sized mirrors as earrings, and a necklace shaped like two C's connected at the backs. "No you're a prisoner like me."
