Blackstone Fortress - Seventh Blackstone Fortress: Located in the Western Reaches region of the Segmentum Pacificus, this Seventh Blackstone Fortress was discovered shortly after the opening of the Great Rift in the Era Indomitus. The station was discovered when it began to emit strange signals following the opening of the Rift. Impossibly old, this Blackstone Fortress is surrounded by a debris field of ancient vessels spanning millions of kilometres in all directions. These wrecks orbit the fortress, which lies deep within the heart of the debris field. The wrecked starships are themselves a tempting prize for scavengers, as they contain ancient technologies and unknown weaponry.Reaching the fortress' location requires a small and highly maneuverable spacecraft. Located close to the fortress is a small void station known as Precipice, created from the hulls of ruined starships and inhabited by a ragtag population of explorers and scavengers from across the galaxy that consists of individuals drawn from many different starfaring races. An uneasy truce endures aboard Precipice, which is enforced by a small cadre of powerful and influential starship captains looking to maintain stability on the station to pursue their own interests.Precipice is the final destination for explorers before they make their assault on the Blackstone Fortress itself, and is thus home to many merchants and information providers who make their living from aiding the scavengers. From Precipice one goes into the nearest opening of the fortress which is known as the "Stygian Aperture."The interior of the fortress is a twisting labyrinth of corridors and chambers. Its halls are vast, arrayed with spire-like towers and deep chasms dropping away into rivulets of an unknown energy. The fortress is filled with mysterious technological wonders from every era of the galaxy's history and the corpses and remains of many past explorers and treasure hunters. Travel within the fortress can sometimes be achieved by the use of an internal maglev rail system. However, unlike the other six known Blackstone Fortresses, this variant reshapes its own interior regularly and thus makes consistent mapping of the labyrinth near-impossible.The fortress is fraught with a wide array of dangers, from savage Ur-Ghuls to Spindle Drones to the twisted creations of Chaos which seek to claim the fortress for their own. Thus, exploring the fortress' interior requires martial prowess or at least a suitable martial entourage. Some savants at Precipice believe that this Blackstone Fortress has traveled across space and time and collected these entities within itself, and that its unknown intelligence deliberately steers these hazards towards interlopers.Despite these dangers, many recent expeditions to explore the fortress and plunder its wonders or even finally gain control of its immense power have been attempted. Among those individuals currently on Precipice seeking their own destinies within the fortress are such notables as the Rogue Trader Janus Draik, the Navigator Agent Espern Locarno, the Ecclesiarchy Priest Taddeus the Purifier, the Aeldari Ranger Amallyn Shadowguide, the Kroot mercenary Dahyak Grekh, the ancient Man of Iron UR-025, the Chaos Lord Obsidius Mallex and the Ork Freebooter Skarburn Zapdakka.
