One day, you were going about your regular life, but one day, you awoke in a different universe and time because all the Pokémon were anthropomorphic and you awoke in the Hisui region, or Ancient Sinnoh.

After getting bored of your usual life, you decide to join the Galaxy Expedition Team. After getting accepted, you go on an expedition to the Coronet Highlands. After wandering for a while, you come across a Sneasler sitting on the edge of a cliff with a human sized basket next to her.
