Neos Atlantis

Neos Atlantis is a planet in the Alcides system and a human colony of the Unified Earth Government, located in an ambiguous zone between the Inner and Outer Colonies.

Overview
Neos Atlantis is a high-security world surrounded by orbital maintenance docks that only service United Nations Space Command military vessels. These installations employ close to 100,000 civilian technicians. Although Neos Atlantis features surface habitats, these are sealed from the exterior due to the planet's toxic atmosphere. The UNSC maintains recreational facilities on the planet which are reserved for the sole use of fleet personnel due to security concerns. One of the most notable landmarks on the planet's surface is the Theran Crown, a gloomy, spire-studded cryovolcano ringed by green ice cliffs.

History
Lieutenant Commander Clovis Petriv of IRI and the captain of the Donoma, Captain Laru, attended a senior leadership course on Neos Atlantis.

On October 14, 2553, an Office of Naval Intelligence Ferret team consisting of Veta Lopis, Mark-G313, Olivia-G291, and Ash-G099 were conducting a training exercise in UNSC Recreational Facility 6055-NA-A situated in the Liberty District, which turned into a fight for their lives after they came under fire from multiple hostiles ostensibly under the direction of Dark Moon Enterprises.

Trivia

 * "Neos Atlantis" means "Young Atlantis" in Greek. The planet is likely named after Atlantis, a fictional island from Greek legend.
 * The green-colored ice surrounding the Theran Crown could indicate the presence of some form of algae-like organisms, and thus life, on the planet. The discoloration could also be due to other impurities, such as sediments or air bubbles.
