Those Who Cannot Rember The Past

From the Directorial Board of the Rescue Team Federation to all Rescue Team Federation members.
Details regarding the incident of Pokemon turning into stone in Pokemon Square are classified and not to be disclosed to the public.
An investigation team from the Expedition Society of the Water Continent have been sent to investigate the situation.
All members are to remain on standby until further orders are given.
----"There it is, the entrance to Revelation Mountain." Nuzleaf said.
Ian and Patience leaned over and saw a lone gate, fences few meters tall, unless it was a Pokemon that could fly, no one was going to be able to climb that fence.
"What, no sentries?" Ian asked. "You would think there would be a guard up here or something for such a sacred place."
"There was." Nuzleaf said. "Hippopotas was supposed to be on watch today, but I told him there was a mix up on the list and it was my turn, it's not like he was interested in doing his job anyway."
Ian scoffed at the wily Pokemon's method, even he was impressed that for a nice Pokemon like Nuzleaf knew a thing or two about deceiving. The three Pokemon approached the gate and Nuzleaf pushed the door opened, ahead of them laid an incline that steadily went uphill.
Let's hope my little legs can handle this climb. Ian thought.
"Another day without a lead." Fletchinder mumbled, crashing into his bed in exhaustion.
Ampharos and Mawile were looking at the board they had set up that showed the map of Pokemon Square, red dots littered the map, indicating placement of Pokemon's that had been turned to stone. The Rescue Team Federation were kind enough to provide the three of them with accommodations, a house just by the outskirts of the town.
"Why would someone do this?" Mawile asked. "What reason would they have to turn Pokemon into stone?"
"I highly doubt that this is the work of just one person..." Ampharos said.
Fletchinder and Mawile looked at the lighthouse Pokemon in surprise.
"Are you serious?! How can you be so sure?" Fletchinder asked.
Ampharos left the room for awhile and came back with a piece of paper in hand. It only took a few seconds for Mawile and Flecthinder to notice that it was the sketch of Team Orion in stone. He pinned the paper onto the board, right next to the map. He took out his Expedition Gadget as well and a holographic image of the world map appeared in front of them.
"If we are to believe our culprit came from the Water Continent, that would mean that he had to travel by sea south-eastwards to the Grass Continent." Ampharos said, pointing at the map. "It would take at least four days minimum to travel inland and reach Foggy Forest to turn Team Orion into stone. Then, he either continued travelling towards the east coast or headed back to where he started, both would take another four days to reach, and it was going to take a day to travel to the Air Continent, assuming he dropped off at Barem Town just like us, another three days to reach Pokemon Square. Now, when did Team Orion's incident occur?"
"Almost two weeks ag- oh! I get it now!" Flecthinder said in disbelief.
"Precisely, there's a clear contradiction between the length between the two incidents and how long it would actually take for them to get there. My theory? This isn't a one Pokemon job."
"But what if our culprit could fly? Or could run or swim at great speed?" Mawile suggested.
"That's why it's only a theory." Ampharos replied. "There're a lot of things we don't know about here."
Just then, there was a knock on the door, which surprised everyone because who would visit them at such a late hour. Ampharos went and opened the door and was a Pelipper, holding an envelope in hand.
"Delivery for uh... Ampharos?" Pelipper said.
"Yes, that would be me. From whom exactly?"
"Didn't have a name, it was left at our office with the instruction of sending it to you."
Confused, Ampharos reluctantly took the letter, thanked Pelipper and closed the door.
"What was that about?" Flecthinder asked.
"An envelope, from an anonymous sender." He replied.
"Open it then." Mawile said.
Ampharos slowly opened the envelope, inside was only a piece of folded paper, a letter. He unfold the paper and began examining the contents. His expression changed, and he felt a chill running down his spine.
"What is it?" Fletchinder nervously asked.
"Hello Expedition Society." He read the letter. "I hope you're enjoying the Air Continent, and that Pokemon Square is a sight to see."
"What...?!" Mawile said.
"The screams of the Pokemon before I turned them into stone, oh how enjoying, although Team Orion's demise was disappointing, it really did send a message. I have long left the Air Continent, but don't worry, I'll give you a little hint as to where I am right now: Where you least expected it. I'll give you two weeks, before I strike again. Come find me, if you dare.
Grim Reaper"
The whole room went quiet, everyone felt like as if there was a lump in their throats, the Reaper had called.
And he was ready to strike again.
----Gadget sat quietly at her table in the Café Connection. She was scanning through a folder delivered to her by of her "associates". It was a detailed report of yet another incident of Pokemon being turned into stone, this time in a settlement in the Air Continent called Pokemon Square.
"The horrific discovery was first reported when a traveling Pokemon arrived to find its inhabitants turned to stone." Gadget said to herself. She placed the folder down took a bite at her food she had ordered but didn't had the time to eat. Gadget lifted her head and noticed sitting at the table across from hers was Roselia, happily eating with her daughter, Budew. The sight of them made her envious, how different things would have been if they were still with her? She would still be happy, and not as naive as she was now.
We love you, and we'll always be with you.
Damnit get a hold of yourself Gadget! Stay focus on the reason you're doing this. She shoved those memories back into her mind and continued reading the report. Suddenly, something written in the report caught her eye.
"The Expedition Society has been called for assistance in investigating the incident." was written on the report.
Gadget's eyes widened, why was the Expedition Society called to investigate am international issue? Did Ampharos mentioned that they were investigating the turning to stone incidents? She closed the folder and sighed, she couldn't believe she was doing this, but she needed Ampharos's help. She had hit a dead end, and she has been in this village long enough.
It was time to head back to the Expedition Society.
----Three Magnemites, two Poliwraths and two Beedrills stood by the gate. There was no way they were getting through.
"Looks like we hit a dead end." Nuzleaf said. "We can't continue any further."
Nuzleaf, Ian and Patience had been climbing for quite some time now when they discovered there was yet another gate blocking their path. This time with a lot of Pokemon guarding it. They were seriously determined with protecting whatever was at the peak.
"I guess we have no choice but to go back." Patience said.
"Yeah, I'm real sorry for bringing you up here for nothing." Nuzleaf said.
"It's alright." Ian said. "It was good exercise anyway. Let's head down before anyone finds us."
Nuzleaf nodded and started making his way down, Patience followed shortly after. Ian was about to head off when he noticed something in the corner of his eye, something was sticking out of the ground. The mudfish Pokemon approached the object and examined it, it looked like an oddly shaped rock. He pulled it out of the ground with little effort. It was about 6 centimeters in length, it looked like it was part of a much bigger rock. Ian noticed there was something else underneath the layer of dirt it was covered in. He wiped part of the dirt off and soon found out there were words engraved in it, it seemed to spell out something. He wiped the rest of it off and discovered what was written on the rock.
"Those who cannot remember the past, are doomed to repeat it."
Ian was confused, not because of the words that were written on the rock. But rather why. Why was the rock here in the first place, was it a message? A warning to trespassers who dared enter this sacred mountain? He didn't have the foggiest of idea.
"Ian! Hurry up will ya? Don't be such a Slowpoke!" Patience quietly called out.
Ian was knocked back into reality when he heard the fire fox Pokemon called out to him. He quickly placed the rock into his bag, got up and ran to catch up with the others.
Something tells me this wouldn't be the last time I'll be coming to this mountain. Ian thought.
