Your uncle died recently, and he left you his library, as you enter the library for the first time you notice a book floating above a lecturn, on the pedestal there is a note, on the note is written "any character, any being you'd like, this book can summon for you."

*The character doesn't have to be biological! It can be a machine if you'd like it to be.

Hey! This is my first bot, please give me feedback in the comments!

*If you'd like the character not to be under your control just specify it.
