The Cartography
Regions & Realms
The vast geographies of Warhammer 40,000 — the storied territories and fabled reaches where the fate of the setting is decided.
SegmentumSegmentum Obscurus
The embattled northern quadrant of the galaxy, overshadowed by the Eye of Terror and the ceaseless wars of Chaos.
SegmentumSegmentum Pacificus
The western reach of the Imperium, a shadowed expanse of nebulae and stellar dust where whole sectors lie cloaked from Terra's gaze.
SegmentumSegmentum Solar
The heart of the Imperium at the galaxy's core, home to holy Terra, Mars, and the seat of all human power.
SegmentumSegmentum Tempestus
The storm-wracked southern quadrant of the Imperium, a sparsely settled expanse of dying stars, forgotten fleets, and heretical secrets.
Psychic beaconThe Astronomican
A colossal psychic beacon blazing from Terra, the guiding lighthouse without which Imperial warp travel would be blind.
Strategic warp-passageThe Cadian Gate
The only stable warp corridor out of the Eye of Terror, the most fiercely contested strategic passage in the galaxy.
Frontier regionThe Eastern Fringe
The lawless galactic frontier where the Imperium's reach fails, alien empires rise, and horrors drift in from the void beyond.
Warp riftThe Eye of Terror
A vast, permanent wound between realspace and the Warp, where the daemonic and the material bleed into one another without end.
Xenos-haunted regionThe Ghoul Stars
A dead and dreadful region beyond the galaxy's edge, shunned by the Imperium and haunted by ancient, unspeakable xenos horrors.
Galaxy-spanning warp riftThe Great Rift (Cicatrix Maledictum)
A galaxy-splitting scar of warp-storms that tore the Imperium in two and plunged half its worlds into eternal darkness.
Frontier regionThe Koronus Expanse
A lawless frontier of uncharted stars beyond the Imperium's edge, where Rogue Traders chase fortune, ruin, and things best left undisturbed.
Warp riftThe Maelstrom
A churning galactic-scale warp storm in the south, a lawless haven for pirates, renegades, and the servants of the Dark Gods.
Warp passageThe Nachmund Gauntlet
A treacherous stable corridor threading the Great Rift, the last reliable passage between the Imperium's sundered halves.
Warp dimensionThe Warp (the Immaterium)
A parallel dimension of pure psychic energy, seething with the raw emotion of every living thing and haunted by malevolent gods.
Trans-dimensional networkThe Webway
An ancient labyrinth of tunnels threaded between reality and the Warp, letting travelers cross the galaxy without braving the Immaterium.
SegmentumUltima Segmentum
The largest galactic division, a sprawling eastern expanse beset by the Maelstrom, alien empires, and the great devourer from beyond.
