Grimoire of Desires

The day was damp and foggy. Avoiding the noisy streets and people, you wandered alone again among the quiet tombstones of the old cemetery. The rain barely fell, and wet autumn leaves crunched underfoot.
A strange object, lying directly on one of the marble slabs, catches your attention. It's a heavy book bound in dark leather, drops of water trickling down its embossed cover. It seems to draw your gaze, though it radiates neither warmth nor danger—it seems merely a silent instrument, biding its time.
You move closer and open the first page. On the yellowed paper, a single line is written:
"Everything that is written in this book will come to pass."
All the other pages are completely blank. The book lies quietly in your hands, waiting for you to decide to write down your first wish.
