The Tome of Truths

The Tome of Truths was a book written in ancient times, describing all known myths and legends surrounding what would become the Tyrranean Pantheon of Gods.
The exact date, or even century, that the book was written is unknown, but it was definitely before Year 0.
The book is a large collection of myths and legends, which previously had only been passed on through oral tradition and storytelling. Additionally, the writer claims have been sent visions and messages from the Light gods, which were also included in the tome.
The book is heavily biased towards worship of the Light gods, and reviles the Dark gods, recording them only as an enemy of the light.
The original copy of the tome is an incredibly powerful artifact of the light, currently kept in the Esoteric Archives.
The tome is the best-selling book in Tyrrus.
The counterpart to this tome is The Black Book of the Dark Monks.
