!disclaimer! I do not own Undertale or any of its characters…obviously, if I did I would make sansby and charisk canon…all rights go to Toby Fox.

Oblivion: I stare at the blinking cursor…it's as if it's taunting me…it's trying to make me write…but I can't from writers block…the smug bastard…

Tem: what is hooman talking 'bout now?

Oblivion: nothing tem, nothing. So yeah, this will go up around the same time as chapter four of my fanfic island story, maybe a day before. This is the long awaited prequel to flaming skeleton, it will explain why Chara, Flowey, and Asriel are all alive in the Underflame universe, also how Sans and Grilby hook up. Sadly there is no charisk in this story but there is in the story 'flaming skeleton' set in the same universe. Have fun reading this ;)

p.s. if you want to know Frisk's and Chara's genders in the AU, you'll have to read 'flaming skeleton' but for now, I will use non gender pronouns.

This is it, the last Genocide run, all I need now is to reset and then I can save Asriel. I've compiled enough determination for two whole human souls, meaning if I can transfer them into flowey he and Asriel should live after the barrier is destroyed. I stare at the reset button, it has a slight glow that's comforting, I take deep breath and slam down my hand onto the reset button and everything goes black, I wake up on a patch of flowers, as per usual, but something's off. I turn my head to see another person lying on the flowers as well. I crawl over to them and nearly jump back in shock. It was Chara. They slowly open their eyes and sit up, they yawn and stretch and then realize that something's not quite right. They look around and jump up when they see me.

"What did you do!?" They yelled.

"I didn't do anything! If anything this is your fault! I bet you planned this!" I screamed back.

We bickered for a few minutes and finally agreed this was on accident. We just sat there in awkward silence, waiting for the other to say something. After about ten minutes I decide to break the silence.

"So what now?" I ask.

"To be honest, I have no clue," they said, a little downcast "wait, how much LV do you have?!"

I hadn't even thought of that, if I don't have enough then we can't save Asriel! I pull up my menu to see…I have all of the LV I had when I reset. You would have thought that it was used in bringing Chara back.

"I-I have all of it," I tell them.

I wonder what brought them back, could this be an irregular timeline? We once again sit in silence trying to think. After a half hour passes Chara gets up and starts walking towards the ruins. Not knowing what else to do, I follow them. After a bit of walking I expect Flowey to pop up with his usual speech, but instead I hear a small voice from behind.

"Ch-chara? I-is that you?"

Chara turns to see flowey staring up to her, "Yes, Asriel, it's me."

"How are you alive? And it's Flowey now," He says, irritated.

"Well, Asriel, it's a long story. I'll just say that Frisk has brought me back," Chara puts their hands on my shoulders and gives a light shake "We're also returning you to normal"

"Impossible!" Flowey scoffed "you bring me back to normal? Ha! Don't get my hopes up."

"It's true!" I shout.

"Yeah, sure kid. I'm outta here."

Flowey disappears and not soon after, we make our way to Toriels house. Chara just bursts in yelling, "I'm home!" We hear a startled scream from down the hall. The events that followed had a lot of crying…I mean a lot of crying. Toriel ran out of her room, flames in hand, and nearly roasted Chara to a crisp. When Toriel realizes who she is attacking, she breaks down into a sobbing mess, Chara tries to console her…but she breaks down as well. I do my best to comfort the two sobbing messes, but it seems that they just need to hug it out themselves for now. I decide to walk around and look for irregularities; they've been popping up everywhere three timelines ago. And yes I found one, the books on the shelf look untouched and brand new almost…strange. I check Toriel's journal and I'm not sure, but some of the jokes seem to be even worse than before…or maybe that's just me. I come back to the sobbing duo and tap Toriel's shoulder.

"Oh? Who might this be, Chara?" Toriel asked

"She's the one who brought me back," Chara tried to explain.

"How?"

I just shrugged my shoulders. I'm not even sure how, but I know it has something to do with the irregularities.

"We're trying to bring back Asriel as well," Chara said.

Toriel gasped in shock, she went rigid and then she started sobbing…again…which led to Chara sobbing…AGAIN. This is getting old so I try to get Chara's attention. I whisper in their ear that we need to go. She nods and I see they're still crying. I wipe a tear from their cheek and hug her, I don't know why, I just…did it. The hug was starting to get a little long so I let go. I can't tell if I heard Chara whimper or not. We said goodbye to Toriel, then Chara and I started to walk towards the basement.

"Wait," Toriel Grabbed Chara's arm "Maybe you two should stay the night, it's awfully lonely here and I'm sure you two must be shocked by all that's transpired."

I nod and look to Chara. They nod as well and so we stay the night. We eat pie and drink some hot chocolate, I explain to Toriel about all the timelines…all of them. She's silent for a while and she just stared into the fire.

"I completely understand why you've done all this," Toriel looked on the verge of tears "And I thank you, thank you for going through all of that to bring me my children back. I can't imagine how it must have felt to do what you did…I'm sorry for all you've been through, my child."

"I think that Sans has taken this worse than you have, I don't think he'll be as forgiving…" I whisper.

"Whatever do you mean?" Toriel asked

"Sans can remember timelines…"

The rooms temperature dropped ten degrees.

"Oh my…" Toriel looked a little uncomfortable "Why don't you two go to bed"

Toriel stands up and douses the fire and lights our way with magic instead. We make it to Chara's & Asriel's old room. Chara crawls onto the bed I usually sleep in during timelines and I crawl into Asriel's. I close my eyes and try to sleep. Tomorrow will be a next step towards the end, the true end, a step towards righting my wrongs, and finally a step towards bringing Asriel back. Slowly, oh so slowly, sleep over took me.

Oblivion: Yeah, remember how I said there would be no charisk? Yeah screw that crap, charisk all the way! This will explain a few unanswered questions from the main story "Flaming Skeleton".
