Underworld

Beneath the surface of Mythosa, there are endless miles of tunnels, passages, and cavern complexes. Some are close to the surface or inside of mountains, while others are so deep that they are as alien to the sunlit world as would be another plane. The entirety of the subterranean world is known as the "Underworld".

The Underworld is also home to a great variety of plant and animal life, much of which is intelligent. Orcs, giants, dragons, and the Drakari are just a few of the better known races that inhabit the world beneath the ground.
