One day, in the Galar Region, the world Champion Seth Eaton was catching Pokemon for research for the regional professor, Professor Sonia, and the Kanto professor, Professor Oak. His main partner was a small brown dog-like animal with a fluffy tail and a mane. The tail had a white tip with heart shapes on it.

This was an Eevee, but Seth nicknamed her Eva. Seth had recently brought some of his best Pokemon to the Galar Region. These included Charizard, the Flame Pokemon, Venusaur, the Flowering Pokemon, Blastoise, the Shell Fish Pokemon, and the two most trusted Legendary Pokemon he had, Mewtwo, the Genetic Pokemon, and Rayquaza, the High-Sky Pokemon.

Seth had also had brought his Mega Ring, along with his Dynamax band. He was walking in the Wild Area, when he saw a Dynamax pit glowing, with Gigantamax energy.

"Eevoi," said Eva.

"I see Eva," said Seth, "Wanna go for it?"

Eva gave him an ensuring nod, and Seth jumped in, but he didn't land right away, he was falling. Seth was unexacting this held onto Eva with all his might so she wouldn't leave his side.

After one hour, Seth opened his eyes and saw that he wasn't falling anymore. He was firmly on his feet, and he still had Eva in his arms and his Poke Balls still on his belt, and that they were all in an ally. Seth walked out, and was amazed at what he saw. The city was beautiful. Was he in Luminous City?

No, the tower wasn't anywhere to be seen.

Celedon City? No too big.

Rhyme City perhaps? No, there were no Pokemon walking around with the humans.

He decided to go find a library. When he found one and entered, he asked, "Could you tell me where the history and biology books are please?"

"Over to the right, on the left side," said the librarian. As Seth walked off, he noticed that some of the people had animal ears and other assortments. He was confused.

When he got to the history section, he and Eva couldn't believe it.

They were on another planet!

They found that the planet's name was Remanent, and that there was another species of humans called the Faunus, who were the ones who had the animal ears and assortments.

They also learned about something called Aura, which creature with souls had, which protected them like how the Pokemon move Protect does.

People also here have a special power with their Aura called a Semblance, which reflects their personality sometimes, or even boosts attacks.

They finally learned about the Creatures of Grimm, soulless creatures that are hell-bent on the destruction of humans. Seth then walked out and was thinking of ways to help him get home.

Five days later, Seth was happy, but he didn't know how to make money.

To help him out, he used the poke dollars that he had to buy some stuff to help him get settled down, like a communications device called a Scroll, some food, and a few new clothes.

He walked around, thinking deeply, when he ran into a young woman.

"Oops," said Seth, "Sorry."

"It's okay," said the woman.

She then saw Eva on Seth's head and said, "Awww, what a cute little one."

"Eevoi!" said Eva happily.

"What is it?" she asked.

"This is Eva, my main partner. She is an Eevee."

"An Eevee?" "Yes, but before I explain, my name is Seth Eaton."

"I am Yang Xiao Long."

"Nice to meet you Yang, now, Eva is a special creature called a Pokemon. They are rare, and I have been able to train some."

"Really, like what?"

"Well, I have seen some things, like these."

Seth pulled out his Rotom Phone, and showed her the pictures of some Pokemon.

"Wow, these look incredible," said Yang.

"Yeah, and I've been helping some friends of mine study them when we find them."

"Any specific places?"

"If I told you, you wouldn't believe me."

Yang just shrugged, and said, "Okay, but just be sure to let me know if you ever find any more."

"Sure thing Yang," said Seth.

Well, that was nice, said Mewtwo within his Pokeball.

"Yeah, well, let's just get going. Gotta see if anything can help us get home."
