Colonize Ash

 Planetary Colonization

Attempts to colonize Ash-type planets without some form of topological control has a long history of failure. Life-sustaining habitats desiccating to the point of death and greenhouses succumbing to irreversible desertification were not unknown. Fortunately, with improved technologies these problems are a thing of the past.
