Helen Magnus and Nikola Tesla look at a holographic map of Hollow Earth.
Hollow Earth is a subterranean world below the surface of the planet Earth, inhabited by both humans and abnormals. It consisted of an enormous cave network that crisscrossed the Earth's crust and in some placed penetrated the mantle layer. Beings from Hollow Earth on the surface are called Hollow Earther(s).
History[]
Season 3[]
| Episode 3x10 - "The Hollow Men": The city of Praxis is located there, and its guardians patrol the surrounding area. There are multiple gateways to Hollow Earth that can only be opened by a keystone. All the entrances to Hollow Earth are equipped with sensors and vampire detectors, and if they detect vampire blood, then a laser field activates which forces the intruders down the vast network of granite tunnels to the nearest Praxian garrison. The tunnels within Hollow Earth are well lit due to many pillars that outline the cave systems. There are many vicious abnormals within Hollow Earth, many of whom are extinct on the surface, including the basilisk. Humans and abnormals not only live in the city but also in the out lands where they live in nomadic cultures or out land tribes and move to seasonal camps to farm large mushrooms called rashi. All beings within Hollow Earth are ruled by Praxis, often with an iron fist, although it has been noted that Praxis's harsh laws are the only thing keeping Hollow Earth's dangerous abnormals from overrunning the entire planet. The rock surrounding the city contains a high percentage of lodestone and magnetite which helps with their communications but also acts as a natural electromagnetic shield, but the supply tunnels a few miles above the city are primarily granite in composition. The only way to enter Praxis is by airship or by one of the outland gates. |

Calderas[]
Three main arterial pathways of Hollow Earth connect to dormant volcanic calderas on the surface (the Chilean caldera, Indonesian caldera, and Russian caldera). In early 2011, all three of these calderas had portions of it blown open.
| Episode 3x20 - "Into the Black": When Adam Worth's time portal collapsed, the resulting expelled/expanding energy ripped through Hollow Earth, vaporizing the ruins of Praxis and was able to blast a navigable opening in each of the three calderas, allowing abnormal tribes to breach the surface. | |

Abnormals[]
Notes[]
- Speculation: It can be presumed that at least some of the tunnels seen represented within the holographic globe during the final scene of Episode 3x06 - "Animus" connect to gateways.
