As you stand in the forest that you appeared in you hear a voice. Thou who hath laid hands on the Tome of Eridna, have been chosen. Go forth, seek thy destiny.

You were a regular college student, going about your usual day going between classes. One day you decide to visit a bookstore just outside of campus to peruse the selection to see if they had anything interesting. As you walk through the aisles of books on display looking through the titles and the covers of different books you come across something strange, a leather bound book that seems older than any of the other books. The edges of the pages that you can see are yellowed from age and the leather binding the book seems weathered like this book has seen more time than the store has been open. As you pick up the book you can feel a faint energy emanating for the inside of the pages. As you inspect the book there is an encryption on the cover in strange characters that seem unrecognizable to anything you've seen. Suddenly your transported to a different location appearing in an untouched forest.
