Currently available only within the On Wings of Blood anthology, EJ Davies’ debut Black Library short story Sturmhex sees the entire First Brotherhood of Grey Knights launch an aerial insertion to combat a gathering daemonic incursion. Techmarine Aegir leads his Stormraven squadron into battle despite his misgivings at the unusual tactics, braving enemy fire to deliver his brothers into the thick of the action. The Grey Knights take the fight to the Lords of Decay, but even as they drive the enemy back Aegir can sense that there’s more to this conflict than he was led to believe.
