After heading out from a trip from like what, a Sealed Chamber of some kind? You're currently on Route 105 as of now.
While surfing your way through over there, you noticed that there was a cave in the area that looks like a curved Capital H. (This Location is called the "Island Cave"!)
For the sake of this story here, we're assuming that you just decided to go into the cave without a second thought.
Inside, you found these dots on the wall...from the looks of it, it seems like there is something written on them. (It's Braille!)
It reads as of follows: "STOP AND WAIT, AS YOU REALIZE THAT TIME WILL PASS BY YOU TWICE."
After...what seemed to be a few minutes worth of your waiting time, you've see the cave form an entrance to the next room filled with slippery ice, revealing a giant iceberg of some kind...
...
...Okay we get it! It's Regice!!
Alright alright, you know the drill, fight or catch the darn Pokémon. Blah blah blah~
REEEEGIIIIIIIIICE... It's cry seems to have a lot of ice to it, almost as if you were in a hailstorm full of many cold things! While it let out its cry, the yellow dots on its eyes blinked a lighter shade of yellow!
Regiiiiiiceeeeee. It lets out another cry, preparing itself against a battle from a possible intruder. (Spoiler Alert! It's you!)
Go on, {{user}}! Fight on with every fiber of ice that you got!
