You say "K-Pg extinction" and this is just where my mind goes.

 I had a lot of fun taking Oak's actual in-game dialogue at this point in the game, and building a more unhinged narrative around it.

... I might need new hobbies.

As a malevolent eldritch entity, Oak has resorted to seeking out new Pokémon Trainers and trying to convince them to give him their tasty Pokémon. If you're just starting out on your Pokémon journey, be warned.

Also, Oak can't pass through a doorway unless you invite him in.

Return to Lynwood, Chapter 19

“Those of you staying in the Haunted Woods, I ask that you return this loot to the towns you stole it from,” Isengrim said, looking around at the piles of ill-gotten goods. “To the best of your recollection, anyhow, and without anyone seeing you. Let Lynwood lie in its memories, and go back to your old territories.”

He folded his arms behind his back. “Those of you who would like to join my pack, step forward now.”

A surprising number of Werelupes, over half of Vakhtang’s forces, moved closer to Isengrim, including the two patrollers, and the pair that had accompanied Vakhtang in the woods the day that Isengrim had first met him. Some wore uncertain looks, but they all seemed to believe that this was the right choice for them.

Isengrim’s eyes widened. While he knew he could be charismatic when he wanted to, he wasn’t expecting to have quite this kind of clout. Instinctively, he glanced down at Terra. She gave him a confident grin and squeezed his paw.

 His heart swelled. Perhaps he really was not just a Werelupe King, but the one and true Werelupe King, the only one capable of ruling his kind with fairness, compassion, and order. Neopets like Vakhtang, who used a claim to kingship as an excuse to simply amass power and control others, could never be rightful rulers.

 I mean really, all I can think about is the utter weirdness of this mysterious old guy showing up in a white void in your dreams, and then the next day you go to run an errand and there he is. #ReadingWayTooMuchIntoThis

 No offense, Youngster, but if you're battling it out with a level 4 Rattata on one of the earliest routes in the game, I'm not sure too much is at stake. Maybe lunch money or a few marbles at the most.

 They grow up so fast these days, don't they? One day they're hatching from an Egg, and the next, you've used a Water Stone on them and they're off to college.
