13Th Age: Book Of The Underworld

The expanse of the Dragon Empire is nothing compared to the vast and mysterious realms that lie beneath it. Deep within the Underworld lie adventure and treasure—as well as madness and death. But what is reward without risk?

With The Book of the Underworld, designer Gareth Ryder-Hanrahan (Eyes of the Stone Thief, Book of Demons, Book of Ages), reveals the Underworld’s secrets for 13th Age, including:

The lands of the Underworld: the Underland, the kingdoms of the Hollow Realms, and what lies within the Deeps
The mighty dwarven city of Forge, rallying point for the inevitable war to reclaim Underhome
The domains of the Silver Folk elves, and their underground icons: She Who Spins in Darkness, and He Who Weaves with Joy
The threats of Malice, the Drowfort, and the four kingdoms of the Mechanical Sun
Forgotten gods, the gnome academy of magic, monsters, magic treasure, and more!

You’ll also find rules for traveling in the Underworld—including ways to make travel montages more interesting (and hazardous!)—and advice for GMs who want to create adventures and campaigns set in the Underworld.

The passage downward lies ahead. Cold air chills your bones, and you can hear the echoes of something huge and ancient stirring far below. Mutter one last prayer to the Gods of Light, set your torches ablaze, and prepare to enter the Underworld!
