Gav Thorpe’s 70-minute audio drama Asurmen: The Darker Road comes nearly two years after its predecessor in the fledgling Phoenix Lords series, the short novel Asurmen: Hand of Asuryan. This time we see the first of the Phoenix Lords arriving at Craftworld Ulthwé in time to join Eldrad Ulthran on an expedition to the Crone Worlds, to claim an artefact that could guarantee the safety of Ulthwé and its people. Accompanied by the head of Ulthwé’s Seer Council, Asurmen guides his fellows through their perilous journey, but his presence doesn’t necessarily denote success for the mission.
