Geology and terrain
A rebuilt volcanic world
A rocky planet of volcanic regions, mountain chains and broad temperate basins. Its surface has been reshaped on a planetary scale, leaving an unusual record of artificial topography.
Climate and atmosphere
Ash, mist and climatic recovery
Its climate shifted from a cool, ash-filled atmosphere to a warmer, greener regime. Volcanic aerosols and the restored position of the planet still influence local weather.

Biosphere
Life under a changing sky
Mammals, birds, crops and hardy plants occupy environments adapted to ash, darkness and volcanic soil. Biodiversity is greatest in the restored temperate regions.
Habitats
Basins, burnlands and mountain margins
Protected basins and fertile river regions are the most stable habitats. Arid burnlands, volcanic slopes and ash-prone zones create sharp ecological boundaries.
Open questions
A planet that records its transformations
How quickly can a damaged climate settle into a new equilibrium? Species distribution and the long-term effects of atmospheric engineering remain open questions.
