Episode Summary: With a goal in mind, Mason continues his quest. Searching the vast multiverse for a way to defeat Beast with One Eye once and for all.

Disclaimers: I do not own Gravity Falls or the Relativity Falls AU idea.

Author's Notes: Good Morning my amazing readers! I know you hate when I do this, but I had an awesome idea! It's something that I haven't seen done in any Gravity Falls retelling yet! I want to explore what happened to Ford after he was sucked into the portal. His 30 years away is never really spoke of in the show. However, in the journal, he gives a full account of his time shortly after the events of the episode He's Not What He Seems.

It's an amazing adventure and I look forward to sharing it with you.

As always, thank you for reading and please review!


Interdimensional P2: The Quest

It was a perilous journey, one that as time dragged on seemed more and more unescapable. His quest was to learn all he could about Beast with One Eye in the hopes that he would defeat him. He had met many friends and twice as many enemies as he lived over 100 different lives. He traveled with bandits, pirates, and once a tribe of octopus-armed warrior piglets. He had learned to speak 13 languages, got in a fistfight with a talking chair, and got some questionable tattoos. He had his regrets about the later, one of the warrior piglets had introduced him to time punch and now he wore a turtleneck to hide the evidence of his embarrassing choices.

He studied every ancient texts he could find, compared notes with elphen scholars, dined with monsters, and was briefly made king of the Finger Dimension. A reign that was shortly lived when some 7-fingered man arrived to upstage him.

It took great wits to survive the sometimes harsh and alien worlds he found himself in. Thankfully Thanks to his dimensional translator, he was able to talk his way into receiving food and shelter. Still, there were many things he did that he was not proud of. Not everyone was willing to help him in fact, a number of dimensions consider him an outlaw. He couldn't blame them not really, he had stolen knowledge, weapons, food supplies, anything he needed. All in the name of his quest.

He told himself it was worth it; the knowledge had paid off. He now knew, thanks to some platypus bear looking monks the likely way to defeat Beast with One Eye.

"What you need is a Quantum Destabilizer." A monk had told him over meditation.

"A what?" Mason had asked. It had took many days sitting outside their cathedral before they had finally let him in. Of course, he wasn't surprised, many people avoided talking about the "Beast With One Eye" as Beast with One Eye was popularly called. The Triangle minus only sought the total destruction of innocent worlds, and those who sought him out only looked for personal gain. It was only after he mentioned that he wanted to destroy the demon did they allow him inside and took him more seriously.

"A Quantum Destabilizer." The head monk, a platypus bear by the name of Aang repeated. "It is a ray gun that can destabilize a demon's physical form. But you must aim for his core."

Mason nodded. "And this destabilizer will it destroy him forever?"

"It will destroy his physical form, and make him too weak to make another." Aang revealed. "As for completely destroying him, that is harder. No one had ever been able to destroy the beast completely, just weaken him, slow him down."

"prolong the inevitable." Mason said darkly.

"I'm afraid so." Aang looked solemn. "I am sorry if this is not the good new you were looking for.

"No." Mason assured him, jumping to his feet. "You've been a great help, this may not stop him, but it could by my world some time."

"It is very complex weapon to design." Aang warned handing over a blueprint of sorts.

"I am sure I'll manage." Mason said, even though it looked to be the most difficult invention he'd ever attempted to make. He found it strange a monk would have a blueprint to a weapon that could destroy a being with one blast. He also found it convenient that said monk had left out the fact that making one was against dimensional law. He didn't care though; he would go to any length and as several more years followed his noble cause made him the most wanted man in the multiverse.

He found it Ironic that he, the once golden child of his family was now the multiverse's most wanted criminal. If his parents could see him now, they would feel great shame. He wondered what his sister would think. Did he really want to know? She had been one of the people who begged him to stop. Screamed that his obsession was getting out of hand. He should have listened, but no he was the "Smart One." Not like those smarts did anything for him now.

He pushed the thoughts away as he pressed forward. Hiding his face with the hood of a heavy cloak he entered a new wormhole. He had yet to find one leading home, but that was just as well. He was just glad to be leaving, the M-Dimension was without a doubt the most frustrating place he had ever been. Everything there was in the shape of the letter M. A fact that turned out to be a big design flaw for appliances like vacuums and hoes. If he never saw the letter M again it would be too soon. What made it more insufferable was he found nothing there that would help with the destabilizer.

Mason exited the wormhole and stepped into a white space.

"Hello there traveler." A voice said.

Mason turned to his left to see a strange creature, of course that was nothing new. In fact, many citizens across the multiverse that he was strange too. This one however had an hourglass looking head with one eyed above the other He lacked a nose and had a very unsettling large mouth. Oddly enough he had hair and wore a long cloak, again the choice in wardrobe wasn't a surprise. Most wear the same in many other dimensions. "Hi." He said. "Please can you tell me when I am?" He asked.

"Aw a drifted, are we?" The creature asked. "Well, my friend you are in for a treat. My name Sirin and you are about to embark into the Do-Over-Dimension." He explained.

"The What now?" Mason asked.

"The Do-Over- Dimension." Sirin repeated. "Here time yo-yos forward and backwards in a seemingly random pattern."

Mason looks like he swallowed a goldfish. "So, anything you do here can be undone at random?" It was a horrifying thought. What if he walked in this dimension and he aged 100 years or worse? What if he aged backwards until he was a useless infant?" What if he finished his destabilizer only for time to yo0yo it right back out of existence.

"Well as the saying goes:" Sirin laughed. "One step forward, infinite steps back, then two and a half steps forward, for no reason." The guy wasn't really selling this place and mason looked back the way he had come.

The wormhole was still holding up, and it could for several days, but was it wise to go back? He could waste valuable time looking for another one, one that might not exist. The truth was he had yet to find any real pattern to these things. Often, he'd have to ask around and see if anyone had seen such a thing. It was funny, on earth admitting to seeing portals to other worlds would get you locked up in an institution. However, many travelers came and went through wormholes just about every day in the places he had been to so far. Finding them had been easy, but sometimes when one disappeared it took many years for the new one to be found.

Mason could not afford to wait that long. He had made a terrible mistake trusting Beast with One Eye and he had to fix it, he had to stop his once Muse. "Is there a way, you know; to tell if a change is about to occur?"

"Why yes." Sirin gives him a device, some sort of large future tech pocket watch with different symbols. "Our Timelineoligist give their predictions on the days forecast every morning."

Mason looks at the watch, seeing the different signs and symbols flashing. It was outlandish, but then again humans once thought predicting the weather correctly was a sign of witchcraft. So, he really had no room to judge. He didn't plan to stay long anyhow, sure he couldn't build his weapon here, (not with the chance that it would unbuild itself) but it didn't mean this trip had to be a total waste. "I'm in search of vast knowledge, is there anything here for research."

"We have many libraries." Sirin told him. "What did you have in mind?"

"I'm looking into interdimensional criminals." Mason explained. "Call it a hobby of mine." It wasn't a right out lie. Mason had learned a lot when hunting for parts for his destabilizer. Like for example that The Beast with one Eye and his friends were interdimensional criminals and that the Nightmare Realm was their prison. A broken world where dangerous monsters were locked away in order to preserve the balance throughout the rest of the multiverse.

The Beast with One Eye had been banished there after he "liberated" His own dimension. Starving for chaos he and his friends destroyed world after world, until finally justice was served. The last world they destroyed became their own personal prison. It became a world where they could cause all the destruction they wanted. However, Mason knew that they saw no fun in breaking an already broken world.

That's why the beast wanted out and his rare gift of dream and mind manipulation gave him an opportunity that others did not have. The beast had used that gift well and had managed to almost escape several times. He was terrified to learn that his own race was his favorite pawns, to learn that he had fooled so many like him. It rubbed him in all the wrong ways, he wasn't special, he wasn't a brilliant muse looking for a mind to inspire. No that had been a lie, he was a monster who had destroyed to many human lies before his.

Still, despite the growing odds, Mason wanted to be the last and since doing anything physical was a waste of time here he might as well learn all he can. He had to many questions after all, like for instance, why couldn't the beat and his goons use wormholes to escape their prison? Where they not stable enough for beings of their mass power? Or was he perhaps unaware of their existence?

There was so much unknown, what weakness did the enemy have if any? What could he use as a back up if plan A went horribly wrong?

The beast was always several steps ahead in their game, and he needed to do the same if he wanted to stand a chance.

"There are few that explore such dark parts of the multiverse." Sirin told him the answer he already knew so well. It was like this everywhere; they would all rather pretend the best and his friends were not real. A monster told about to trick children into behaving, surely a real monster like that didn't exist.

Mason, however, knew better. He had met this monster, and knew his tricks, he knew he was no figment of the imagination. The best would come for them all, one day he would get free; it was only a matter of time. In the meantime, Mason would use was ever information he could find, he would not go down with out a fight.

Feeling satisfied with his renewed convictions he gave the guide a curt nod. "Thank you." Then he was off moving forward once more just as determined as before. He approached exited the white void between worlds and entered the awaited world.

His only thought was the quest, and his desperate need to complete it in time.
