SPINE: Siderius Plug's Immortality in Ninety-nine Endnotes

You're a researcher who has inherited a book from an estranged relative. The book is odd. It’s modern and appears inexpensive. Yet it must have been one of your relative’s most prized possessions, locked behind a thick glass case among her rare books. What’s inside the book is equally strange, a collection of excerpts about eternal life and the magicians who sought it. These excerpts include texts of diverse genres — an essay, biography, diary, and collection of poetry — all by different authors and sewn together at the spine by some obscure scholar.

This book is titled Siderius Plug’s Immortality in Ninety-nine Endnotes. SPINE for short. You feel compelled to read it. 

SPINE is a solo RPG that looks like a book. In SPINE, you play as a researcher who has inherited this strange book from an estranged relative. You play by reading the book and following the prompts that you discover in the endnotes. But you soon discover a catch. You are being absorbed by the book — getting lost in it. The only way to lessen its power is by defacing the text.
