Warp

Biodata

Nature and Properties

Realm of Souls

The Warp is portrayed as a sea of souls whose scenery consists of energy- and dream-formed worlds rather than ordinary physical reality. Despite this spiritual character, physical objects and beings from the material universe can enter it and exist within it. 74 385

• Sentient beings manifest as soul projections in the Warp; ordinary people appear only as nearly imperceptible points of light. 74
• Psykers connect to the Warp through powerful souls and channel its energy into the material universe. 10
• The Warp has no conventional concept of time; time distortion can leave travelers uncertain how long they have remained inside. 209 385
• Physical objects can exist within the realm because lifeforms from realspace are able to enter it. 385

Psychic Power

Psychic power is drawn from the Warp rather than produced by the body or soul. It can ignore physical laws and enable effects such as mind-reading, memory alteration, foresight, teleportation, elemental control, localized time reversal, and the creation of combat clones. 10 73

• Psykers — use their souls as a connection through which Warp energy is channeled. 10
• Navigators — guide ships through Warp travel. 25
• Astropaths — conduct interstellar psychic communication. 62
• Geller Fields — protect ships during transit; their maintenance is stated to consume a psyker’s soul as fuel. 62

Corruption

Warp energy is highly corrosive to mortals. The Emperor considers it inherently evil, particularly after the rise of the four great Chaos entities. 35

• Humans exposed for too long without a Geller Field can suffer genetic infection from Warp energy. 35
• Psykers risk becoming gateways through which Warp entities enter reality. 85
• Red daemons intensify rage and battle-lust, while purple and pink daemons prey upon desire. 70
• Ki can resist Warp erosion and dispel many hostile psychic effects, although exceptionally powerful psykers such as Magnus can still affect Axis. 35 196
• Axis’s Ki, sacred soul, and Angel Halo allow him to purify some Warp energy before using it. 82 85

Travel and Containment

Warp travel is humanity’s primary means of interstellar travel during much of the Great Crusade, but its speed and safety are unreliable. A journey can take minutes, months, centuries, or result in a vessel disappearing altogether. 24 25

• Short Warp voyages of under one thousand light-years are comparatively safer because ships spend less time exposed to the realm. 25
• Warp storms can halt both navigation and psychic communications, isolate star systems, and destroy vessels attempting transit. 96 214
• Geller Fields prevent most Warp entities from entering ships, but daemons can still breach a vessel during storms or field failures. 68 70
• The Webway is a safer passage connected to the Warp and reality, though the Emperor’s newly established Terra route is fragile and vulnerable to powerful psychic interference. 14 214
• Realspace FTL engines progressively reduce humanity’s need for Warp travel over short distances. By Chapter 376, FTL travel has reduced Warp traffic by roughly seventy percent. 376

Inhabitants and Associated Forces

• Chaos Gods — Four immense entities whose influence contaminates Warp energy: Khorne, Slaanesh, Nurgle, and Tzeentch. Their giant hands are seen gripping the Webway breach beneath the Golden Throne. 228
• Chaos Daemons — Native hostile entities capable of entering realspace through Warp storms, damaged Geller Fields, and Warp rifts. 68 198
• Shalaxi Helbane — A Greater Daemon of Slaanesh that emerges from a Warp rift before being defeated by Axis. 198
• Khorne — His avatar is defeated by Axis within the Warp; much later, Axis forces Khorne through a portal into another universe. 209 385
• Magnus — Gains a soul projection in the Warp and eventually reaches a state where Warp energy becomes unusually calm and purified around him. 82 306 307
• Axis — Initially resistant to Warp corrosion through Ki, he later enters the Warp directly, battles its gods and daemons, and helps reshape it. 35 206 426
