Praxis



 is a large city located in Hollow Earth. It is sometimes referred to simply as "the underground city". It seems to be Hollow Earth's center of government and technology.

Government
Praxis is governed by a powerful, conservative and isolationist Senate, but much power is placed in the hands of a chief executive, Ranna Seneschal. It is unclear whether Ranna came to power through election, appointment, inheritance, or some other means, and she is described only as the city's leader. Ranna and the Senate do not always see eye-to-eye, and she has been seen to take covert action without their consent.

Defenses
The city was founded by incredibly intelligent human refugees from the surface who lost a war with the ancient vampire civilization. The vampires made several attempts to assault or infiltrate the city, which has led to their heavy development of defensive technologies, many of them targeted specifically at vampires. The entrances to Hollow Earth are equipped with vampire detector technology which detects the presence of vampire blood by scanning those who pass through. Holomaps recording Praxis' location utilize similar technology and cannot be accessed by vampires.

Technology
The people of Praxis have incredibly advanced technology such as organic nanite matter, A.I. maglev transit systems, dirigibles, energy weapons and shields, and advanced holographic technology as seen with the holomap. In the city's command center, the Praxis garrison use holo-transfer data and neural interface devices to control communications and weapons guidance. The people of Praxis also use medical nanites and they can revive people from death by flushing their DNA with positive ions. The city also has A.I. robotic drones and chromographic sensors. The city has many storage facilities that contain weapons and anti-matter (Kellorem device). As a safety feature, the transit system can use a holo-drill to burrow through rock if the main access tunnels are blocked. The people of Praxis have sacred laws and do not abide in unlawful transmutations so they are also capable of locking the DNA of a HAP in order to prevent the transformation from human form.
