Raven's Flight is the first audio drama for the The Horus Heresy series that was not originally released as part of an anthology or other release. Raven's Flight was released in both compact disc and MP3 formats. It was written by Gav Thorpe, directed by Lisa Bowerman and performed by Toby Longworth. It was later published in printed form in Shadows of Treachery (Anthology) and re-released in an enhanced audio edition in 2015, but can still be bought as a stand-alone audio drama.
After the horrors of the Drop Site Massacre, the Raven Guard are trying to survive in the caves and mountains of Istvaan V. Their plight is desperate, and escape from the roaming Traitor Legions seems impossible. Can they hold out against the forces of the World Eaters long enough to reach an unlikely salvation?
Raven's Flight follows the desperate Raven Guard Legion after their betrayal during the Drop Site Massacre of Istvaan V. The Raven Guard find themselves with only 3,000 Astartes remaining out of the 80,000 that once comprised the Space Marine Legion. Meanwhile, on the Raven Guard's homeworld Deliverance, Praefector Marcus Valerius is haunted by a dream of dying ravens. Believing these nightmares to be significant, he attempts to convince his superior, Commander Branne, to send support to Istvaan V, fearing for the rest of the Legion and their Primarch Corax. Ordered by his Primiarch to remain on Deliverance, Branne is skeptical of Valerius' dreams, at first dismissing them outright. But after much deliberation, he makes due course for Istvaan V to determine the fate of his Battle-Brothers.
