Sius

Sius is a star system with five planets. It is located in the Moltke Cluster.

Malisk I
Malisk I is a resource-rich desert world, having been harvested for materials ever since the Eteno discovered space travel and credited with fueling early colonial expansion.

Malisk II
Malisk II is a water world exhausted of its mineral wealth. Despite this, it flourishes as the capital of the Eteno Imperial Triumvirate, and is the homeworld of the Eteno.

Malisk III
Malisk III, however, is a frigid world with methane oceans existing underneath miles of ice. Methane extraction on Malisk III began in 2130 AD.

Malisk IV
Malisk IV, while further out from Sius than Malisk III, has an extremely large and hot core keeps the world's surface warm. Rich in gold, magnesium, silicon, and iron, a multitude of mining companies ran extraction operations on the surface. Harbinger attacks destroyed these extraction operations, and only since 1,002 ATGW have mining companies returned to the planet.

Tyrgen
Tyrgen is the last major mass of the Sius system, and the furthest out. A large ring system adorns the gas giant of five times the mass of Jupiter, formed of the debris from the collision of two ancient ice planets, Malisk V and Malisk VI. Gas mining stations surround the planet, and have been harvesting Tyrgen for almost 400 years.
