Immaterium

Biodata

Nature and Cosmology

Relation to Realspace

• Psychic power originates from the Immaterium rather than from the psyker wielding it; the Orks' WAAAGH! Field is treated as an exception. 14
• Qin Xa identifies the Veil as the boundary surrounding the material universe and separating it from the Immaterium. Threads attached to the Veil form the Web of Fate, which some psykers inspect to make prophecies. 14
• The Immaterium does not follow ordinary spatial or temporal rules. Distance can become irrelevant, and psychic energy, thought, language, and will can directly shape the environment. 72 286
• Realspace universes appear within the Immaterium as bubbles; each encompasses its own Veil, Web of Fate, and material reality. Warp exploration also reveals apparently infinite layers, with deeper layers containing prior ones as insignificant “dust.” 589 592
• Ether is described as the Immaterium’s fundamental substance. It can be catalyzed into matter during the birth of a real universe. 687

Inhabitants

Hazards

• Material beings exposed to the Immaterium without a Gellar Field may suffer madness, mutation, or physical transformation; even ships can grow flesh under prolonged Warp influence. 252
• Uncontrolled psykers may detonate, release their powers erratically, or open portals that summon hostile beings. 12
• Daemons and other entities are drawn to the bright soul projections of psykers, seeking to possess, consume, or exploit them as gateways into realspace. 183 333
• The Librarium teaches that no Warp entity should be trusted after an apprentice’s pact with purported “elves” resulted in dozens of souls being dragged into the Warp. 72
• Qin Xa’s encounters with the Fifteenth Legion demonstrate that temporarily helpful Spirits can foster dependence and conceal the broader dangers of mutation, corruption, and hostile entities. 250 252 290

Travel and Protection

Immaterium Technology

• An ancient Nucerian device used Immaterium-based perpetual-motion principles to generate food and air before Angron destroyed it over concerns about its danger. 124
• The Colony Ship’s tiny core is an Immaterium-based supercomputer whose computational “hardware” largely exists in the Warp rather than conventional physical machinery. 333
• The core’s Immaterium projection establishes local time, maintains a firewall against entities, and purges approaching creatures as if they were computer viruses. 333
• Qin Xa and the Maker later create time and causality within the Immaterium itself, intending to use those principles to anchor Tzeentch’s ever-changing existence. 687
• The Emperor rejects ascension within the pure Warp because its corruption could turn humanity into daemons or lesser Warp creatures; his proposed Ether Human ascension must instead occur within the Webway. 687

Qin Xa and the Immaterium

• Qin Xa first enters the realm through psychic meditation and perceives it as an ocean-like expanse filled with impossible landscapes and predatory entities. His self-preservation instinct manifests as a transforming submarine, weapon, shield, or enclosure. 14 15
• Unlike other psykers, Qin Xa cannot perceive a Soul Projection of his own. This prevents entities from directly affecting his soul or forming soul contracts with him. 15 250
• He uses this anomaly to navigate the Warp, manipulate psychic currents, track entities through Psychic Sight, and confront Greater Daemons directly within their native realm. 164 286
• The Emperor and Malcador speculate that Qin Xa may be an entity resembling an advanced Primarch or an Immaterium Lesser God associated with purification, though they acknowledge that these are only theories. 183
• Qin Xa’s ability to draw publicly available psychic energy into himself lets him neutralize Warp-powered threats, including Erebati’s gem-fed strength. 509

Story Role / Major Arcs

• Qin Xa’s early dives establish the Immaterium as the source of psychic power, a realm beyond conventional logic, and a direct threat to unprotected psykers. 14 15
• The Twelfth Legion begins using Warp travel more confidently after acquiring an ancient Void Shield capable of supplementing Gellar protection. 134
• Qin Xa’s discussions with Avida and Asar expose the conflict between the Fifteenth Legion’s trust in Spirit contracts and the Twelfth Legion’s fear of corruption. 250 252 290
• The Warp becomes the battlefield for Qin Xa’s conflicts with Greater Daemons, where conventional psychic attacks prove insufficient against beings sustained by abstract concepts and will. 286 287
• Discovery of the Colony Ship’s Immaterium computer reveals that the realm can be structured, programmed, and defended against through advanced technology. 333
• Librarium expeditions document the Warp’s layered, infinite structure, but Qin Xa erases the explorers’ memories after compiling their findings into one thousand books. 592
• In the ascension plan, the Immaterium becomes both the source of humanity’s potential transformation and the realm where Qin Xa and the Maker prepare to eliminate Tzeentch and Nurgle. 687
