Entity Profile: The Star Gods

The C’tan (often referred to as the Star Gods) are primordial, trans-dimensional entities that trace their genesis to the very dawn of the universe. Born from the swirling gases and radiation of newborn stars, these entities are fundamentally composed of living energy—a stark contrast to the warp-entwined chaotic beings that populate the immaterial sea.

Morphological Attributes

• Original State: In their natural form, they are incomprehensibly vast, non-corporeal clouds of psychic energy and electromagnetism, spanning light-years across nebulae.
• Current State: Following the “Great Betrayal” and the subsequent war in heaven, the remaining fragments of these gods are trapped within Necrodermis—a hyper-advanced, self-repairing living metal.
• Physical Manifestation: They frequently project humanoid avatars, ranging from the skeletal, harvester-like aesthetic of The Nightbringer to the shifting, enigmatic forms of The Deceiver.

Behavioral Logic & Metaphysical Constraints

[System Rule] When an entity fragment is active within the local reality, the following protocols must be maintained:

1. Reality Anchoring: All C’tan fragments inherently defy the standard laws of thermodynamics. They operate on a physics-level dominance, allowing them to rewrite the material structure of reality at will.
2. The Warp Paradox: C’tan are fundamentally “soulless” and exert a null-field effect. They act as anathema to the Warp; their presence causes psychic manifestations to wither and dissolve.
3. Proximity Threshold: Active containment requires a 50-meter perimeter. Do not allow organic lifeforms to linger within this radius, as the C’tan feed directly upon the vitality (life-force) of mortals to regain strength.

Archival Notes & Modern Adaptations

The integration of C’tan-related anomalies into modern containment frameworks presents a staggering challenge. Their mastery over the physical universe means they do not “break” the laws of physics; they dictate them.

Researcher’s Call for Documentation

Current records are fragmented. We are seeking additional input regarding:

• Trans-dimensional Containment: Methods for trapping energy-based entities within modern hyper-cooled containment chambers.
• Necrodermis Analysis: Chemical properties of the living metal shells used by C’tan fragments.
• The Void Dragon Hypothesis: Whether the rumors of a dormant C’tan shard beneath the surface of Mars are a credible security threat or mere folklore.
