Book of the Netherworld

The Book of the Netherworld is a text that has long since been lost to this world, but is often referenced in other ancient sources. Due to these references, we know that the Book of the Netherworld described the journey of the god of radiance, Kael Doras, through the caverns of Erebus. These descriptions seem to have focused on the interactions between Kael Doras and the inhabitants of Erebus, including rewards for the righteous and punishments for the enemies of fate and the worldly order.
