The Chaos Executor-class Grand Cruiser' is a Vengeance-class variant that is no longer in Imperial service. Few were ever constructed, mostly in the shipyards of Hydraphur and its surrounding Forge Worlds. The Executor was a Lance boat, and as such was much liked by fleet commanders because it served as a counter foil for other more heavily gunned Cruisers. Over the years, the Executors numbers dwindled as each was lost in battle. One of the last remaining squadrons of Executor-class Grand Cruisers, under the command ship Blood Royale, was stationed as part of the massive fleets defending the Cadian Gate. During a fleet action against Chaos vessels raiding from the Eye of Terror, the Blood Royale and her sister ships were part of the pursuit force. The squadron had held the line and forced the raiders to disengage while the Blood Royale and a dozen other vessels gave chase. None were ever seen again, their fate remained a mystery. Most believed they had been drawn into a trap and destroyed. Five centuries later three of the missing vessels, including the Blood Royale, were identified as part of the Renegade warfleet of Warmaster Arca Vilespawn. They are thought to be the only Executors left in existence.
