Amazon.com description: Product Description: Two audio dramas from the multi-million selling Horus Heresy series.

The Dark Angels and the Night Lords fought one another to a bloody stalemate during the Thramas Crusade and, though the Lion eventually claimed victory, it left both Legions scattered and under-strength. Back on Caliban, those Dark Angels loyal to Luther begin to grow impatient for a return to past glories, allowing the corruption at the world's heart to spread. Meanwhile Jago Sevatarion, First Captain of the Night Lords, languishes in a gaol cell in the heart of Ultramar. Far from a spent force, both Legions must consider where their own personal loyalties lie, and what path they will take in the days and months to come.
