Neos Atlantis


Alcides system[1]





Toxic to humans[2]





Unified Earth Government[1]


Neos Atlantis is a planet in the Alcides system and a human colony of the Unified Earth Government,[1] located in an ambiguous zone between the Inner and Outer Colonies.[3]


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,[3] these are sealed from the exterior due to the planet's toxic atmosphere.[2] The UNSC maintains recreational facilities on the planet which are reserved for the sole use of fleet personnel due to security concerns.[3]

The planet has a green, icy surface.[4] 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.[1]


In March 2526, during the early stages of the Human-Covenant War, the 11th Marine Force Reconnaissance/ODST was stationed on Neos Atlantis, before moving to engage the emerging Covenant threat in the Outer Colonies.[4] Lieutenant Commander Clovis Petriv of the Incident Response and Investigation branch and Captain Laru of UNSC Donoma had attended a senior leadership course on Neos Atlantis together.[5]

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.[1]

Behind the scenes[edit]

"Neos Atlantis" means "Young Atlantis" in Greek. 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.
