User blog:IRPeacock/TWOF Book 5(?)

Hola, my Coca Colas! My geeks and fantasy freaks! My fanfic-hunting fanatics! Bella here. Since I added Undertale to my TWOF series, I've been thinking a lot about the AUs (alternate universes) that revolve around it. So last night, I pictured a scene where River (the River Person in Undertale) takes Cassie to the Multiverse to team up with characters from the AUs. Of course, things don't go as planned and the Evils follow them into the only official Undertale AU: Deltarune. They land in the Dark World and the Evils kill everyone, leaving Kris, Susie and Ralsei as the only survivors. The girls and their friends save them, but are separated when the Evils throw them into portals that lead into separate AUs in the Multiverse: Underfell (Cassie and Ralsei) and Timetale (Alex, River, Kris, and Susie).

ANYWAY! I've been thinking a lot about Cassie and Ralsei's trip into Underfell, so I've decided to make a oneshot of what it would be like if they landed in the spot in front of the throne room in New Home right before they fight UF!Asgore. Here it is, and I hope you enjoy!

***

Cassie and Ralsei were lost in a world of darkness. Everywhere they looked, there was black with wisps of red light swirling around them. Suddenly, they landed hard on the ground. Cassie groaned and twitched her wings as she lifted herself into a seating position. They were sitting in a large room with gray walls laced with ivy, water canals on either side of the room, and the symbol of the Delta Rune on the floor. There was a large doorway in front of them, and four gray pillars covered with vines stood on either side of it.

Ralsei sat up and fixed his glasses as he looked around the room. "Ugh...where are we?" he asked.

"I don't know," Cassie said. She could've sworn she had seen this room before, but she couldn't put her finger on where exactly they were. She stood up and helped Ralsei to his feet, who flicked his tail nervously.

"River and the others must've gotten sent to the other AU," Ralsei said. "But which one are we in?"

"Maybe we should look around for someone," Cassie said.

Cassie and Ralsei walked to the edge of the doorway and peered inside. The room beyond the doorway was a throne room similar to the one in the Underground, but larger and more intimidating. Golden flowers covered the entirety of the floor, and their petals were dull and torn. In the center of the throne room was a purple throne with a golden frame, and sitting in it was a huge Caprian monster. He had white fur, long ears, a snout, fangs, and tall bovine horns that curved above his head. He had black hair, a beard, and a small golden crown atop his head. He wore a dark purple cape over a suit of golden armor, and had large golden pauldrons on his shoulders.

She recognized that monster, and suddenly realized which AU she and Ralsei had fallen into. She leaned back against the wall, and placed a hand on her head. Small beads of nervous sweat emerged on her forehead, and her heart was pounding a mile a minute.

"Oh God, no," Cassie whispered. "No, no, no, no, no..."

Ralsei noticed her worried expression and grew one on his own face. "What's wrong? Who is that?" he asked.

Cassie looked at him with wide fearful eyes. "We're in Underfell," she said gravely.

Ralsei went pale and placed a hand on his chest. "If we're in Underfell, then that must be..."

"Underfell Asgore," Cassie finished for him. She knew from fanart and gameplays of how powerful UF!Asgore was.

Ralsei looked like he was about to cry. "W-what are we gonna do? He's gonna kill us if we don't..."

Cassie walked over to him and knelt down to his eye level. "Hey, don't worry, little buddy. Once we're done with him, River and the others will find us," she reassured him. "I know this AU like the back of my hand. As long as I'm here, we'll be okay."

Ralsei calmed down and wiped his tears away. His jaw trembled and he nodded shakingly. "Okay, let's go."

Cassie took his hand in hers and walked into the throne room. They stood in front of UF!Asgore, waiting for him to say something. He was eerily still, as if he had expected them to come. He lifted his head to look at Ralsei and Cassie.

"So, you've finally arrived, human," UF!Asgore said. His voice was deep and rough. Cassie had heard many iterations of Asgore's voice before, but none of them were compared to hearing it in person. "At long last."

UF!Asgore rose from his throne, revealing his face. Ralsei cowered behind Cassie when he saw the Caprian monster's face. He had blood red eyes with yellow sclerae and a scar over his left eye. He looked back and forth between Cassie and Ralsei, and she saw a glint of memory flash across his eyes once he saw Ralsei. However, the tense expression on his face was unreadable.

He chuckled darkly. "It's funny. Very few of you humans actually make it here," he said. Cassie was confused; was it really that hard for him to realize that she wasn't a human? "But how fitting, in the end, the final Soul makes it here to my domain."

Ralsei gulped, and spoke up. "Um...I don't mean to insult you, Your Majesty, b-but Cassie isn't a human. She's a halfblood," he peeped.

UF!Asgore turned to Ralsei with fury in his eyes. "I do not care what she is. She is close enough to a human that she will do," he said. He turned back to Cassie. "I suppose we shouldn't act like we don't know what's going to happen next. I have awaited this day for a very long time. And yet, I still don't understand you humans, why you fall here. Is it curiosity, idiocy? Or is it something darker?"

Cassie opened her mouth to speak, but UF!Asgore held up his hand before she said anything.

"I'm not finished," he said. "No matter what that reason is, it does not matter now. Nothing matters now. You are the final Soul that is needed. The friendships you have formed, the people you have 'saved' and given 'hope' to. None of it matters anymore."

He walked to the doorway behind the throne and gestured for Cassie and Ralsei to follow him. Reluctantly, they did as told and walked down a long hallway with UF!Asgore following closely behind them, telling them that their one chance of escaping and making it out alive was gone. They hoped with every fiber of their beings that they could talk him out of fighting to a point where they wouldn't get hurt. Cassie, Ralsei, and UF!Asgore walked through a large doorway and entered a room of darkness.

"Come, children," UF!Asgore's voice beckoned, sending chills down their spines. "Prepare for what fate has granted you."

Cassie and Ralsei could hardly make out the figure that towered above them.
