Davin

A desert planet from the Horus Heresy stories.

Davin is a planet that appears in The Horus Heresy series. The short story Sermon of Exodus is set across the desert wastelands of Davin, where the followers of Chaos prepare to leave the planet; it is a prequel to The Damnation of Pythos. Another story, The Serpent, features a Davinite priest, Thoros, who overthrows a nascent Chaos cult, presumably on Davin itself.
