Frozen Worlds
Snow, ice and cold. Home to an ore that reacts at a touch, the one a Coolant Jacket needs.
Ice worlds, tundra and frost reefs. It snows here, the water is often frozen, and the cold hurts. Bring an Insulated Suit or build a Climate Unit.
Signature ore
An ore ending in -rime, -quell or -frost, with Reactivity of 88–100. A sheet of it, with glass and ice, makes a Coolant Jacket.
