Just before the launch of Warhammer Online, book publisher The Black Library released the first novel, Empire In Chaos, based on the fantasy MMO. Today the game's publisher Electronic Arts announced details of the second Warhammer Online novel, titles Dark Storm Gathering.

Scheduled to be released to stores this spring, the novel will have the following storyline from author Chris Wraight : "Human and Elf adventurers are forced to form an uneasy alliance with the armies of the Empire to repel the forces of Chaos. Across the lands, the grim march of Tchar'zanek, dread Champion of the fell powers of Chaos, is underway. Throughout the Empire of Man, the toll from plague and mutation continues to grow, and hope begins to fade. Only the intervention of the High Elves offers respite, but they are beset by foes of their own, the murderous Dark Elves. When the prospect of treachery behind Imperial lines looms, four heroes based on careers in the game – Archmage, White Lion, Witch Hunter and Knight of the Blazing Sun – must work together to uncover the corruption before all is lost."
