In the grim darkness of the far future, there is only war. But war is waged in many ways. From the dark places where 10,000-year-old psychic warriors interrogate living machines from a time before man, to a treacherous assassination plot that could bring an end to a centuries-old legacy of honour, to relic hunters who want to wrest secrets from a plague-ridden traitor or cross swords with a sinister Chaplain of the Dark Angels, this collection of four audio dramas showcases battles of the mind and spirit in which the victors will be those with the strength to prevail against not only their foes but their own weaknesses.
