Gelida and Glacies are both frozen ice worlds orbiting each other. Gelida is larger and is considered a planet. It is the ninth planet in the Vamana system. In 4212, a human probe discovered the system, and a few months later the Confederacy of Humanity sent colonists there and settled colonies on the terrestrial planets. A few colonists settled on Gelida and Glacies, and discovered a massive underground ocean similar to Europa before terraforming.
