Crypto-forming was the process of radically reshaping the geography, ecosystem, and noosphere of a planet, like a kind of cultural or technological enhancement combined with terraforming.

In preparation for the War in Heaven, the Nine Homeworlds were created through crypto-forming.

Faction Paradox crypto-formed Fallahal to make it suitable for Remote shock-troops. (PROSE: The Book of the War)
