Dry Gaian Type world with a cold climate, with an average temperature of around -50 °C. ocean cover on a TundralXeric world is between 0-25%; compare with GaianTundral and TundralPelagic worlds.

Oceanic ice, even near the equator, can be up to 1 kilometer thick or greater. With almost no precipitation the continents are barren dry wastelands. On land life is restricted to microbial forms, while in the oceans it is typically found only around hot springs and thermal vents.
