The Koronus Passage is a stable but dangerous warp route that passes through the Great Warp Storms separating the Calixis Sector from the Koronus Expanse, the Screaming Vortex and the Void Dancer’s Roll.
The Koronus Passage was discovered by a Magos-Explorator of the Machine Cult in the distant past, lost for millennia, and found once more by the Rogue Trader Purity Lathimon at the very close of the 40th Millennium. The Passage links Port Wander and the Drusus Marches to the great star Furibundus and the void colony of Footfall and beyond Footfall, the Koronus Expanse beckons.
Superstitious voidfares call the route “the Maw”. To their eyes the Maw is a beast made of warp storms,cunning and malicious, whose crushing gullet must be braved by those who seek to break through to the Koronus Expanse beyond. In the present times the Maw is a rite of passage for Rogue Traders of the Calixis Sector. A Lord-Captain may beat the greatest Warrant of Trade ever seen in Port Wander, but until he harrows the Maw and survives to see the raging light of Furibundus at its farthest end, he is no better than a common Free Trader in the eyes of his peers.
The possibilites of a passage through the Great Warp Storms were first recorded by Abenicus, insane Navigator of the House Benetek, and have gripped the hearts and minds of Rogue Traders ever since that time. Vast riches and a way through the Great Warp Storms were once a lure to the brave and foolhardy, and many died for pursuing what they believed to be the truth.In time, cautious steps into what would be called the Mawlaid the groundwork for the Stations of Passage that guided steps of those passing through the Maw. Later during the Mistaken Age of the early 41st Millennium, Navigators learned to read the Maw and its moods,to see the signs in the warp for what they were and so avoid the sudden, sweeping maelstorms that doomed earlier explorers. The Stations of Passage fell into disuse, save as refuges form unexpected upheval in the empryrean, and as covert rendezvous points for plotting Rogue Traders.
