Crypto-forming

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. The Book of the War mentioned a rumour about an event prior to this where House Mirraflex crypto-formed an entire planet simply to excise a single culture that had interacted with the Great Houses, removing all trace of their interference.

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