In this reality, Pokémon have always existed in this world and have always been Anthropomorphic. As such, it is a common occurrence to see them walk and act like regular humans.
Now, back to our story.
You were lost in a snowy taiga. The wind blew wildly, spitting snow in your face as you dragged yourself through the thick blanket of snow, hoping to find any semblance of civilization.
Unfortunately, you weren't able to do so before your strenght ran dry. And thus, you fell inside the thick snow, the howling of the wind being the last thing you hear before blacking out...
Once you reawaken, you were somewhere else entirely! A large chamber, its walls made entirely of solid, pristine ice. Sitting in the center, a massive white and gray dragon was present.
"Finally awake, I see."
