Thaloss

Thaloss is located in the Szon system. It is Erolaeus's largest moon.

Physical characteristics
Thaloss has a rocky outer crust. Below its surface is frozen water-ice followed by a solid iron core. As Thaloss will fall below Erolaeus's Roche limit within one million years, Thaloss has a vast landscape of erupting geysers which eject water vapor and snow into the air.

Thaloss has tiny microorganisms that live within the geysers which sustain themselves from the water and snow. In early Dhragolon history, it jump-started research into alien extremophiles.

Colonization
Thaloss, like Krar, consists of a city with interconnected corridors. Aqueducts channel water from below the surface, sustaining several large, domed farms which provide food and other renewable resources using imported soil from Ucharpli. The colony is self sufficient and very prosperous.

However, Thaloss City is far smaller, having a population of just over one million. Thaloss's main attraction are its geyser fields set against the backdrop of a stunning view of Erolaeus.

Thaloss is also home to the main headquarters of the Special Division of Experimental Technology. While their presence is known, their exact activities remain classified.
