It's an ancient world, where the pokemon are in sync with nature and modern technology is about 2500 years away. In a quiet village in a lush green valley the fiery sun peeks inside clouds as local residents take part in their daily activities. Unknowing that this was the day where their entire lives, and entire world would change forever.
"Terra can you please get your father from the fields?"
Just then a ruby red Groudon around the age of 10 came out of the hut and quickly ran out to the fields calling his friend Hydra another Groudon but a darker blue. It was about a mile walk so they decided to take the long way around the valley. As they were chasing each other, from the corner of Hydra's eye a cloud of dust appeared. It became larger and it seemed to be a hoard of warriors of some sort on horseback. They immediately ran to Terra dad and said "Teron Teron! There appears to be a group of some sort moving towards us! Do you know anything about it?"
He looked puzzled and said "No the Akkaiadon (Ahh-ki-a-DON) village is not expecting anyone. Be we should go back to the village to make sure everything is alright."
So Hydra, Terra, and Teron ran back to the village and told the local residents about the foreign travelers. But one by one they were put down and no one was expecting company. They dismissed the travelers as nothing to worry about as they all went home.
That night as Teron was about to go to sleep and piercing shriek shot across the village. Bolting out of his house with no little then a pocketknife he realized the travelers he'd dismissed to be friendly were now burning down his village. Running up the one of them he shouted "What are you doing?!" Without even looking the faceless warrior replied "To rid the world of it's impurities of the Akkaiadon, Rannika, Moonplace, and Cirrace tribes." "But why?!""Because of Tyrant orders."
Then the rest of the force came and started raiding homes and murdering innocent pokemon. When word finally got the Terra's mother she grabbed him and Hydra and said "Listen go and escape. Run as far away as you can from here!"
"But why…?"
"Just do it! Now go!"
Both Terra and Hydra ran of into the forest and into the night.
The next day they returned and the smell of wood burning streaked the cool air. When they returned to their village nothing was left. Just smoldering piles of ash were left of a once peaceful and lively village.
"Oh no…" Hydra started.
"No everything is gone! It's over the village the tribe…!"
"Well maybe some of then survived…"
They searched around the surrounding area and didn't find anything. Losing hope they searched the ghost town of their village. Burned bodies of faceless people littered the streets and when they got to Terra's house they saw the worst. Both Terra and Hydra's mother and father had been what looked like brutally murdered.
"No…Not…" Hydra trying to be strong blinked back tears.
Terra then quietly said "I'll hunt them forever. No matter what. Even if it takes me the rest of my life."
