Perdition holds control of the planet's only space port, and the descent is not for the faint-hearted. This monopoly on travel has lead to some resentment from the citizens of Redemption, who see the Perdition citizenry as elitist snobs.
Most mercantile interests (including Navigators) are represented by offices on the Emperor's Regard space fortress. As such, the cramped confines is a melting pot for Rogue Traders, miners from the Crown of Thorns, freighter pilots, various arms of the Administratum, and, of course, a significant criminal element that preys upon them.
The Black Ships often moor here, and a large part of the station is assigned to the Adeptus Astra Telepathica. Large numbers of Astropath Choirs exchange messages with Rogue Trader entourages and those exploring the Nightwall. There are even some Imperial colonies in the Nightwall, but contact with them is patchy at best.
