Nachmund Gauntlet

The Nachmund Gauntlet is the only confirmed gap in the Great Rift, a perilous route that passes through the rebellious Nachmund System near the ancient Eye of Terror.

Overview
An intermittent passage through the Great Rift was discovered, yet it brought little hope to the Imperium. The Cicatrix Maledictum had at least one gap, although others were reported but not confirmed. The passage was near the Eye of Terror, which had been avoided by Navigators since the Great Crusade, for warp storms and strange anomalies had always made the region too dangerous to travel. There, when the swirling nebula lulled, was revealed the Nachmund System. Its Tyrant King, Kaligius, ruled over a Household of Fallen Knights that had not been seen since the Horus Heresy. Claiming Old Night had returned, Kaligius rejected communications from the Imperium, instead making pacts with Renegades and pirate fleets. Some starships have run the Nachmund Gauntlet successfully, but many more have been destroyed attempting the journey – the ruined hulks of innumerable craft hang suspended in space as a ship graveyard.
