Warp

Biodata

Nature and Laws

The Warp is a dimension distinct from the Material Universe, composed primarily of spiritual energy rather than matter. Mortal souls possess flame-like projections within it; the intensity of a projection reflects that soul’s connection to the Warp 1.

• Matter is scarce within the Warp, making planets and physical resources objects of intense competition among Warp entities 188.
• The Warp can affect time, space, thought, and physical law. In exceptional regions created by the Great Devourer, the distinction between the Warp and the Material Universe can be completely erased 292.
• The Material Universe normally resists Warp intrusion. Its laws can expel Warp energy and restore damaged reality, especially when supported by C’tan-derived power 143.
• During the opening of the Great Heresy, the Warp is described as becoming a “roaring living storm with a collective will,” fueled by accumulated bloodlust, betrayal, pain, and despair 217.

The Veil

A metaphysical veil separates the Warp from realspace. It limits the ability of Warp entities and deities to remain in the Material Universe, while also restricting physical beings from entering the Warp safely.

• A weakened veil allows lesser daemons to remain in realspace with fewer rituals and makes Warp disturbances more frequent 189.
• Warp gods become more restricted in the Material Universe after fully ascending, while their influence is greatest before their Divine Realms fully enter the Warp 184.
• C’tan power can create zones where the Warp has no foothold, forming barriers that neither repel nor accommodate Warp energy 256.

Psychic Influence

Psykers draw power from their close connection to the Warp. This connection also makes them targets for malicious Warp creatures.

• Stronger Psykers produce brighter Warp projections, which attract Warp entities like “delicious cakes” 1.
• Warp creatures can whisper to, corrupt, possess, or use Psykers as bridges into the Material Universe 1 11.
• Psychic power can be used for attack, defense, healing, telekinesis, pyromancy, telepathy, and interstellar communication 12 20.
• Psychic communication must pass through the Warp, making much Imperial intelligence vulnerable to Chaos interception 37.
• The Khrave use psychic power to remotely enslave intelligent beings through the Warp, harvesting their minds and knowledge through infected hosts 25.

History

Connected Entities

• Material Universe — The Warp’s opposing counterpart. The two realms are ordinarily divided by the veil, though rifts, psychic power, and god-level entities can weaken or breach it 1 143 292.
• Chaos Gods — Their strength depends on negative emotions generated by intelligent life. They use the Warp to corrupt mortals and seek greater access to the Material Universe 171 277.
• Sandman — His growing territory eventually produces a Warp Projection connected to death and soul consumption. The projection develops into the Human Death God, enabling him to confront Nurgle during the God War 24 97 184 224.
• The Emperor — Uses psychic power to suppress Warp storms, clear paths for Imperial fleets, and confront Chaos directly. He also supports research into alternatives to Warp-dependent travel 60 219.
• C’tan and Star God fragments — Their power reinforces Material-Universe laws and can suppress or isolate Warp influence 143 256.
• Great Devourer — Creates a region where the Warp and Material Universe are forcibly merged, but must continually endure the backlash of both realms’ laws 292.
