Pokémon: Summoning Book

This is the world of summoners, the book of contracts, and the awakened life guardian beasts. Charmander, Squirtle, Bulbasaur? Why can I still choose my life guardian beast? Why is my life guardian beast a Pokémon? Did something go wrong with my time travel? I think I was supposed to travel to the Pokémon world! This novel and its characters are purely fictitious.
