Davin

Davin is a feral world where Horus was wounded on its moon and afterwards changed in the Serpent Lodge. The 63rd Expedition had catalogued the planet under the designation Sixty-Three Eight.

Horus received his wound on the moon and was altered within the Serpent Lodge. Years later, Sanguinius, Guilliman and the Lion located the same temple inside the knot of the Ruinstorm. They then attacked the planet with cyclonic torpedoes.

No life remains on Davin. The world is recorded chiefly as the setting of both events: the change in Horus and the later destruction of the planet.
