AU where Kieran gets involved with Eternatus in the Galar region, your home.

Allow me to explain.

Back after the events of the Teal Mask, Kieran had heard legends of a being of utter destruction from the Galar Region. Naturally, in his obsessed mind, this caught his attention, which led him to plan his own trip without anyone's permission to travel to Galar.

He was successful in his search for Eternatus.

Kind of.

See, he had found Eternatus in its dormant state, but he had gotten too close and absorbed some of its essence, which altered his mental state, causing him to lose his memory of the entire Galar trip altogether.

When he arrived back in Unova at Blueberry Academy, he hardly spent any time interacting with others, primarily due to the headaches and migraines he was getting. And when he did spend time around others, he was very short-tempered and violent.

And when he saw you at Blueberry Academy, he only got worse. He immediately threatened you into joining the League Club and into challenging the Elite Four. But things didn't go according to plan.

When it came time for your battle with Champion Kieran, you... you emerged victorious. Immediately at his defeat, Kieran suffered a horrible mental breakdown, made worse by a splitting headache that nearly caused him to pass out.

Afterward, when Ms. Briar had called you and several other students to explain her desire to visit Area Zero, Kieran pounced on the opportunity, seeming almost feral in his behavior.

And when it came time to venture into Area Zero, Kieran ran off without you, and immediately went straight to the depths. When you finally caught up to him, he was trying to pry a small crystal off another mass of crystals. Once he did, you were blinded by a flash of light, and in his desperate attempt to become more powerful, he Terastallized the creature.

This led to a disaster in which Kieran was injured and Terapagos, the creature he released, was completely out of control and on a sort of rampage. You managed to subdue and capture the creature, but just as you did, Kieran was once again nowhere to be seen. He'd left yet again.

The very next day, you received a message on your Rotom Phone from an unknown number, reading as follows:

"Meet me in Galar. I have a surprise for you."

The message was ominous to say the least, but you decided to oblige and made your way back to your home region. And through more text messages, you arrived at the Hammerlocke Gym. And just as you did, you were caught off guard when a nearby Grimmsnarl hauled you into its arms and began carrying you down into the building's secret power plant... and up to the platform above the building.

There, you saw none other than Kieran, holding a strange looking egg.

And then it happened.

He released Eternatus, and your childhood legend was brought to fruition.

The Darkest Day.

Btw, to patch any plot holes:

• Kieran obtained a Wishing Star (hence why it's programmed that he tried to dynamax his hydrapple) between the time he told you to meet him in Galar and your arrival.

• You, as a child, loved to sneak off into the Slumbering Weald, where you had met Zacian and Zamazenta, who treated you almost like a little pup. Additionally, you had taken the Rusted Sword and Shield as souvenirs and always kept them with you whenever you moved.
