The Koronos Passage is a stable but dangerous warp route that passes through the Great Warp Storms seperating the Calixis Sector from the Koronos Expanse. The Koronos Passage was discovered by the Magos-Explorator of the Machine Cult in the distant past, lost for millennia, and found once more by the Rogue Trader Purity Lathumon 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.

The Stations of Passage are locations within real space at which ships can safely drop from the warp while navigating the Maw. Rogue Traders religiously avoided certain Stations, and some still retain an ill reputation. The following list are only some of the Stations within the Maw:

• The Temple
• The Witch-Cursed World
• The Battleground
• The Hermitage
