Marco was speechless. A few minutes after they stepped through the portal the world exploded. The ground shook as a giant X was cleaved into a sky that was no longer blue. It was red.

"Oh no, we're too late." Bill managed to escape his prison. He was free. The earth was doomed because the stupid commission refused to help. As they stared at the dimensional tear, a giant stone pyramid rose above the trees. It was just floating there, mocking the laws of physics.

"Come on Marco, we have to try and fix this." Star pulled him along towards the town. "We can't giv- What the creamed corn is that!" A giant wave of soapy space water was racing towards them and everything it passed through transformed into some terrible beast.

Marco started to run but Star yanked him back. There was no time to run, the wave was gaining on them. Thinking fast, she summoned a force field around the two. The wave crashed upon the two and everything seemed to work until the second wave hit. The ground shook with more force and Marco lost his footing and was pushed out of the field.

"AAGGHHHHHHH!" Marco screamed in agony as mouths with pointy teeth replaced his kneecaps. He collapsed and immediately started convulsing. Star could only watch in absolute horror as her best friends' legs tried to eat himself.

By the time the wave was gone, tears were streaming down both of their faces and Marco was reduced to quiet whimpers. Star could barely look at him because seeing the look of pain in his eyes was too much to bear. She cradled his head in her lap and softly whispered comforting words as she tried to think of a spell that could fix him. She once healed his arm from a tentacle, how different would a leg be?

"Okay Marco, I'm going to try and heal you, alright. Try and stay still." The look in his eyes broke her heart all over again. He was in so much pain all because she decided to bring him along. Star pointed the wand at Marcos knees and closed her eyes. She had to get this right; Marcos life depended on it. "returnio lego normorado." Almost instantly the teeth started to shrink and soon all that was left of that nightmare was some blood on the ground.

Marco took in a deep breath and shuddered. "That was beyond a doubt the most painful thing I have ever experienced. Thank you, Star. Without your spell I'd have been like that forever."

"I couldn't leave you like that Marco. It was terrible just to watch. We'll both need therapists for that one." They chuckled at the attempt to lighten the mood and it was working until they looked at their new surroundings.

"What the…" it was pure chaos. The entire town had turned into some sort of weirdmeggadon. The trees were now… legs? Screams could be heard off in the distance over a chalk-scratching roar. The pair shuddered. This was more serious than either of them were prepared for

"Star, do you think you can cast another magic shield, but this time over the whole town? We have to keep this contained." Star looked at her wand in deep thought and frowned. That shield took a lot of her focus and energy.

"I don't think so Marco. The last one was barely big enough for the two of us and it nearly drained me. I could never keep one as big as you're thinking powered. But…" Star was more focused than Marco had ever seen her in his life. He knew there was a plan forming in that brain. "But my mom taught me this spell in case one of members of the Magic High Commission ever went rogue. It will allow the user to channel magic right from the magic dimension so I won't become fatigued and the shield can theoretically stay on for days."

It was a little ironic since this Bill Cypher used to be on the commission but Marco decided to keep his thoughts to himself and let Star focus. She raised her wand but stopped.

"there is one problem though," she said. "If this shield goes up, then no magic will be able to escape it until I take the shield down. That includes our interdimensional scissors. I can raise it from outside the barrier but then we won't be able to try and stop Bill." Wow, that was a tough decision. They could leave the people of Gravity Falls to suffer while they sent for reinforcements, something that might not even work. Or, they could stay. They could face him head on when he's least expecting it, but they'd be doing it without any help.

What made matters worse was the decision had to be final, Marco realized. If they stayed inside only to fail, the only way out would be to drop the shield. However, that would give Bill Cypher a chance to escape as well. This was an all or nothing ordeal. There would be no second chances.

"Do it, Star. I wouldn't be able to live with myself if we left these people to their fate. We need to at least try and stop him." She nodded to Marco and soon started muttering an incantation under her breath. She began to hover as her hearts started glowing. He couldn't make out what she was saying but strange symbols started appearing around the town, vanishing as soon as they were visible. Finally, the shield was complete. It gave off a blue hue before disappearing like the symbols.

The town may go down in flames, but at least the rest of the world would be protected. For now, at least. The shield should last for a long time but Bill was clever. Marco had his doubts that anything could hold this demon in forever. Somehow, they needed to stop him, which seemed impossible since the most powerful magic users of Mewni failed that task.

"What's next, Star?" Marco decided his legs had had enough time to recover and tried to stand up. His legs were a little too much like jelly for his taste but at least he was standing now. Only been on Earth ten minutes Marco and you've already witnessed things that will haunt your nightmares. Great.

"Well if I was an evil overlord, I would definitely stay in that floating triangle thing. We're gonna go there, meet Bill, and kick his ass."

AN: heyyy, so I'm sorry that I am already behind my updating schedule. I've been writing still, I just forgot to publish it. Also I'm really trying not to rush things. It took four days for Dipper to free Mabel and I want to delve into those days and not just skip over them. The next chapter will be from Dippers perspective. Anyways, thanks for reading my story. I really do appreciate it.

Also, something went wrong when I tried to upload this story. I'm not entirely sure what happened but thankfully someone told me. If you're reading this than I've fixed it yay!
