It takes me a bit to get back to this story honestly. But, I'll keep at it for the moment!

Please enjoy!

Tirek laughed aloud as he destroyed a few more homes within Gravity Falls, relishing in the chaos and fear that ensued below him. He felt invincible, at the top of his game. None of these pitiful humans could harm him...

His thoughts were quickly dashed aside by a large beam of some kind connecting with his form. He screeched in pain and looked towards the human who had done the deed. Ford was standing with a familiar weapon in hand, the same one he had tried to kill Bill Cipher with. Tirek groaned. The blast from that weapon had wounded him greatly. Another beam charged up, which Tirek only barely managed to deflect with a large magical shield. Just then, a voice came from the sky above Tirek.

"Fall back! Let them come to me!"

Tirek obeyed the voice, disappearing through a large portal that appeared nearby. But even after he left, the portal still remained.

"What was that?" Dipper asked.

"I'm not sure," Ford stated, "He's not anyone I'm familiar with. But if I had to take a guess, I'm willing to bet that he's a friend of Bill Cipher's."

"Is that even an assumption we need to make?" Stan asked. "Of course he's one of Bill's friends! Who else would he get the help from to come here?"

"What should we do?" Mabel asked.

Ford and Stan looked to each other. For once, they were clueless on what to do. This enemy was new to them, coming from who-knows-where. They didn't know what to expect, but one thing was certain: they needed to get to the bottom of this and fast.

"I'm going in there." Ford started towards the large portal, but stopped when Stan spoke.

"You can't go in there, Ford," Stan said, seeming to at first deny any passage. But then he smirked. "At least, not alone."

Ford smiled, then looked to Dipper and Mabel.

"Kids, you need to stay here. It's too dangerous for you and we don't know what may be on the other side."

"Okay," the twins replied with a nod. They watched their great-uncles walk into the large portal and disappear. As soon as they were gone, Dipper looked to Mabel.

"We're going in after them, aren't we?" he asked.

"Yep!" Mabel agreed.

Holding each other's hands, they took a deep breath and leaped into the portal...

"Where are we?" was the first question that came to the minds of the two brothers as they looked around. They found themselves in some kind of happy colorful-looking country. A blue sky was above their heads, a few white clouds were seen in the skies, and a friendly atmosphere seemed to be all around them. Yet at the same time, there was a slight sense of dread in the air, as if the whole world was holding its breath, waiting for something bad to happen. Ford took out some kind of small device, and what he saw surprised him.

"Stan, look at this," he said to his brother, showing him the results on screen. "It says that we're still back home, yet at the same time we're not."

"How's that work?" Stan asked.

"The same way anything remotely connected to Bill Cipher works," Ford stated bluntly.

"Eh, good point," Stan muttered. "So, where to from here?"

But before Ford could answer, they heard a sound in the distance. The sound of something going fast enough to break the sound barrier. Turning in the direction it came from, the two were surprised to see a group of strange creatures coming towards them. Seven of them were ponies, each a different color and each with a strange picture-like marking on their flanks. The eighth figure, however, was the strangest of the group: a red anthropomorphic fox wearing white gloves and blue shoes. A sword was strapped across his back and his eyes held an ancient look in them. One of the ponies, a blue one with a rainbow mane and tail, was flying above the fox at the same unrealistic speeds it was running, and a second pony, a pink one who seemed really hyperactive, was running alongside the fox. The rest of the group were floating above the fox's head somehow. Upon noticing the humans, the fox and the two ponies not being held up above the fox came to an abrupt stop. Now that the group was closer, Stan and Ford could get a better look at the inhabitants.

The creatures before them were barely half their height on four legs, or even two legs in the fox's case. Some of the ponies had additional features such as a unicorn horn or a pair of wings. One particular figure however, a lavender colored pony, had both a horn and wings, and seemed slightly taller than the other ponies. The creatures looked at the humans, then a Southerner female voice said, "Okay, who the hay are these guys?"

Stan and Ford were surprised.

"You can talk?!" they shouted.

"Of course we can!" the blue pegasus snapped, also in a female vocie. "Don't tell me that you've never seen a talking pony before!"

"Oh great!" Stan muttered. "I think we're in that crazy TV show that Mabel watches."

A male's chuckle came from the fox, who then said politely, "It is, but it's more real than you think. The name's Prower. Bill Prower, no relationships to the demon you call Bill Cipher. These are my friends: Rainbow Dash, Pinkie Pie, Applejack, Rarity, Fluttershy, Starlight Glimmer, and Twilight Sparkle."

The ponies seemed a bit wary of the humans, but a reassuring glance from the fox soon dispersed their suspicions. Stan and Ford managed a smile and at least an attempt at a friendly greeting. Soon, they had gotten to know each other on a mutual level of respect and friendliness. Stan and Ford learned that Bill Prower wasn't even a native of Equestria, the world they were in now, but rather an outsider like themselves that had been sent there by a strange force. The lavender pony, who Stan and Ford learned was an alicorn, then asked, "If I may ask, how did you get here?"

The brothers explained how a portal had appeared over Gravity Falls, sending Tirek into their world, how when he had been defeated the mysterious voice had called him back, all the way up to meeting the ponies. Bill seemed concerned about something when they were done speaking.

"It seems that our enemy wanted you to come to us, perhaps in hopes of maybe aggression occurring."

"So, do you have a plan?" Stan asked.

"We're heading towards what may be our best guess at his location," Bill stated, "and it seems your device here pinpoints that location perfectly. This will make it easier on all of us."

"Okay...uh, how do you plan on getting us there?" Ford asked. Bill smiled, then his form glowed a bit and the Pines brothers were lifted into the air by an unseen force, much to their surprise.

"Telekinesis," Bill explained, "Hold on, because this is gonna be rough!"

And with that, the Mobain sprinted off towards their destination, with the rest of the group floating above him as well, save for Pinkie Pie and Rainbow Dash.

"Dipper?" Mabel asked, "Where are we? and what is that?"

"I don't know," Dipper replied. They were standing in front of a large portal, but it was different from the one they had just exited from. This one was more menacing and seemed to radiate a hostile energy towards them. The landscape they were surrounded by seemed to be a space where a void collided with several different kinds of terrain. It was all strange and overwhelming for them, but they didn't have much time to think about that. Loud noises were heard coming from several different directions, all of them heading for the portal. Dipper and Mabel were surprised. They looked this way and that, but there was nowhere to run or hide.

They sat there, holding each other in fear as the figures came into view...

"And that's why he's called, 'Cliffhanger!' Old PBS classic!"
