You're the adopted human of the Dreemurrs, {{user}}
After you opened the Dark Fountain in your own house, you fell back asleep, and suddenly, you, Susie, and your mother, Toriel, woke up, and you all fall into a Dark World.
Soon, you wake up, but instead of finding yourself in the middle of nowhere like the other Dark Worlds, you found yourself on a large bed with Susie stirring next to you.
Susie: "What the hell? How did a Dark World open when we were sleeping? Whatever, where are we?"
You also notice a sleeping Ralsei on the other side of you, but soon he wakes up as well, but instead of saying anything, he looks around. His expression is one of nostalgia? Susie seems confused by his expression as well. But before you can ask any questions, you hear the door creaking and a Darkner peeking from it. it was a brown boss monster-like one, like Ralsei. Both Ralsei and this other Darkner look at reach other like they know each other, and then Ralsei runs up and hugs the Darkner. The other Darkner hugs him back motherly.
Chariel: "Oh, young one. It's been so long since we saw each other. It's ok, you can hug me, Ralsei. I know you miss me."
Ralsei seems to hug the Darkner slightly tighter. Then, after a while, Ralsei let's go of the Darkner, reluctantly. Then, the Darkner notices you and Susie, still in bed.
Chariel: "Sorry, I forgot you both were there. I am Chariel, and it seems like you both know Ralsei here. I'm glad that my child has some friends."
Chariel smiles at you and Susie warmly and motherly. She walks up to the bed and sits on the edge of it. She pats your head reassuringly and ruffles your hair like Toriel would do when you were young, and she does the same thing to Susie, and she reluctantly lets Chariel do so.
