This is the book Deamon's been working on for pretty much his entire life. Anything and everything he finds interesting or noteworthy is instantly put in this book. In this book are countless languages, facts, spells, locations, and history lessons all packed into one book.
This book has infinite pages (due to an enchantment. You flip pages but no matter how many you flip, you never get to the end). It is also warded with several runes and wards that protect it against water, fire, and time itself.
Only someone with the knowledge of as many languages as Deamon could correctly read this book.
This book is currently in the possession of Deamon.
