Still in search of allies for their war against Chaos, the Stormcasts brave the Ghurlands... but someone else is there, a champion of Tzeentch seeking a mighty weapon. Only a dangerous mission into the Howling Labyrinth can stop the sorcerer before it's too late. Zephacleas and his Astral Templars have been sent into the wildest regions of the Ghurlands to seek out Gorkamorka, the double-headed god of the orruks and one-time ally of Sigmar in the age before Chaos. However, their search is interrupted in the boneyards of the gargants by the Tzeentchian sorceress Sharizad, who quests for a powerful daemon sword. Aided by the black-clad Sons of Mallus, the Astral Templars must brave the Howling Labyrinth to stop the weapon from falling into the wrong hands – and unexpected allies in this mission might lead them closer to their original goal: meeting the fist of Mork and the fist of Gork. It's a thrill-packed adventure against impossible odds and with some extremely unlikely allies for the Stormcast...
