Mewtwo remembers the days of the war. His captors sealed him away in a Master Ball, the most advanced form of Pokeball, able to detain any pokemon without incident. While he was bound to it, Mewtwo was unable to disobey his captors and was used to fight against the rest of the Ageless. To this day, he regrets what he was made to do.
"Mewtwo, are you okay?" Mia asks, bringing him out of his memories.
He shakes his head, somehow hoping to forget the past. "Yes, I'm fine."
"It is a troubling topic for us all." Lugia says to Mia.
"I'm sorry, I didn't know." she answers regretfully.
"It's all right." Mewtwo reassures her.
"Now then," Lugia announces, "you've come here for answers, haven't you?"
"Yes." Mewtwo tells him. "What can you tell us?"
"Unfortunately, I don't know much." Lugia answers sadly. "All I know is that the Creator sent the Ageless a message explaining that you broke our laws and that you must be executed."
"Then why doesn't he do it already?!" Mewtwo shouts angrily. "If your almighty Creator wants me dead, why doesn't he just strike me down?! Surely he's powerful enough to destroy me any time he wants!"
Lugia exhales, carefully choosing his words. "It's not that simple."
"What does that mean?" Mewtwo continues. "Isn't he the most powerful being in existence? This should be simple for him!"
"I'm not telling you, it doesn't work that way!" Lugia fires back, his patience wearing thin. "There are Rules about these kinds of things."
Mia notices something in Lugia's words.
"Wait," she says to the legendary bird, "you mentioned something about 'Rules' when Mewtwo and Ho-Oh fought. Does that have something to do with this?"
"Yes," Lugia answers, regaining his calm. "Mewtwo, you are young. There are some things that you do not know about because no one speaks of them anymore. But I will tell you the secret history of our world."
Lugia closes his eyes as his explanation begins.
"There are Rules in this world. Rules that only apply to the Ageless. They were written long ago, before time even began. Those that do not follow these Rules are punished for it."
"What are these 'Rules'?" Mewtwo asks.
"The first is this: an Ageless pokemon is not allowed to take the life of another Ageless pokemon. This is why our Creator, Arceus, cannot simply destroy you whenever he wishes. This is why he sent the golems after you to do his bidding. Even the Creator himself must obey these Rules, or suffer the consequences. And the second Rule is this: an Ageless pokemon must always fulfill his or her purpose in this world."
"'Always fulfill his purpose'?" Mewtwo repeats. "What does that mean?"
"It means that we as Ageless have a duty to this world and we must always be working toward it. For example, I am the keeper of the storms at sea. Ho-Oh's duty is to calm the storm and bring peace, symbolized by the rainbow. Together, we bring balance to this world. If either of us were to abandon our posts, we would be punished."
Mia, however, is confused by Lugia's explanation of the Rules.
"Wait, this doesn't add up." she interrupts. "You're saying that Ageless pokemon aren't allowed to kill each other, right? Then why is it that in Hoenn, there are stories of Kyogre and Groudon fighting to the death? Or that in Unova, Reshiram and Zekrom are constant enemies?"
Lugia is aware of what she means and explains, "Yes, you are right. Groudon, the land pokemon, and Kyogre, the sea pokemon, have been enemies since ancient times. And Reshiram, the dragon of truth, and Zekrom, the dragon of ideals, are polar opposites. But have you never noticed that in both of their stories, there is never a victor? In Hoenn, Rayquaza, the sky pokemon, always ends the battle between land and sea and in Unova, truth and ideals always fight to a standstill. That is because their purpose in this world is to fight, but never to win. They will continue their battle until the end of time."
Lugia's story brings a tear to Mia's eye.
"That's so sad. Their duty to this world is to constantly fight each other?"
"I'm afraid it is."
"Well, that's not fair! Who came up with these stupid Rules, anyway?!" she shouts.
"Now that's a good question," Mewtwo agrees. "Who did write these Rules?"
"Ancient and powerful beings that have existed since before the birth of our universe and will continue to exist long after we have turned to dust." Lugia answers cryptically. "You have heard of them. You may have even seen them."
"Who are they?" Mewtwo asks in a whisper.
"The symbol pokemon, Unown."
