GM Xeno World NAAVROS

Designation: Xenos World (Restricted – Observation Level Gamma)
Segmentum: Koronus Expanse
Subsector:
Planetary Class: Temperate / Warp-Touched
Primary Inhabitants: The Veyl-Kyn
Threat Assessment: Amber – Latent warp resonance, memetic distortion hazard, ritualized obedience

The Planet: Naavros

Naavros is a secluded, fertile world shrouded in residual warp energy, once a Yu’vath-occupied node world. Its strange biosphere glows faintly under warped aurorae, and its obsidian plains are broken by the remnants of arcane pylons, runic monoliths, and bone-composite architecture left by the long-dead masters of the Veyl-Kyn.

The Veyl-Kyn: Designed to Obey

The Veyl-Kyn are a xenos species genetically and psychically engineered to serve as perfect servitors to the Yu’vath. Their obsession with obedience is biological.

The Crystal Mind-Core

  • During early neural development (within the first 12 cycles), Veyl-Kyn children grow a warp-reactive crystal deep within the brain, genetically programmed to respond to authority.
  • This “obedience shard” harmonizes with warp resonance and configures the Veyl-Kyn brain toward hierarchical fixation.
  • The result is a species biologically compelled to serve, unable to achieve lasting autonomy without catastrophic emotional consequences.
  • In the absence of a master, Veyl-Kyn exhibit psychic depression and neural obsession.

Psychic Mimicry: Projected Familiarity

The Veyl-Kyn possess a passive psychic projection field, allowing them to appear as pleasing, trustworthy, or familiar beings to any sentient species they encounter.

  • This is not true illusion or shapeshifting, but a low-grade cognitive suggestion field projected subconsciously
  • The viewer fills in the blanks based on comfort, memory, or cultural symbols of trust
  • To humans, they often appear as Imperial citizens, clergy, or even family
  • The effect is strongest within proximity to the Tower of Welcoming, where warp saturation enhances their projection

The Tower of Welcoming

“We were shaped to kneel, that He might rise. We were given voices, that they may scream in harmony. Rejoice—for the Day of Reckoning is near.”
—Inscription on the Throne Steps, Glyph-layer 3

Rising like a blade of regret from the obsidian bedrock of Naavros’s equatorial plateaus, the Tower of Welcoming is a titanic spire of ritual architecture and cultural desperation. Built by the Veyl-Kyn over the course of millennia, it is their central monument, their unifying project, and the final function of their species.

Construction and Composition

The Tower is constructed from:

  • Fused bone-glass: semi-translucent organic composite made from the bones of dead Veyl-Kyn that captures and amplifies psychic energy
  • Prayer-stone: lithic memory-rock inscribed with countless praise-scripts
  • Crystalline psychic circuits: adapted remnants of Yu’vath arcana, pulsing with warp-conductive echoes

From orbit, it gleams like a neural spine—alive with intent, impossible to miss by augury, psykers or warp-sensitive devices.

Function: The Psionic Beacon

The Tower continually emits a psionic broadcast into the Immaterium. It is meant to be impossible to ignore for any sufficiently psychically attuned being. To those who hear it, it carries the emotional weight of a long-lost home calling you back, or the certainty that something is waiting for you, specifically.

Praise-Scripts and Ritual Inscriptions

Every surface of the Tower is etched in fine, swirling glyphs. These praise-scripts do not describe the past, but:

  • Anticipate the glory of the coming master
  • Glorify the Day of Reckoning
  • Offer pre-written apologies for the Veyl-Kyn’s inadequacies
  • List rituals for joyous dismemberment, purification, and sacrifice

The Veyl-Kyn chant these scripts daily, memorizing and vocalizing them in preparation for the day when they are finally heard and judged.

The Throne of Becoming

At the summit of the Tower rests the Throne of Becoming—an obsidian construct laced with warp-conductive veins and memory circuits. It is carved from a single shard of dark crystal fused with psi-reactive veins, capable of amplifying the authority of anyone who sits upon it.

  • Once seated, the tower’s circuits activate and bind the occupant’s identity into the Veyl-Kyn’s shard-mind network
  • The Veyl-Kyn across the planet immediately recognize the seated figure as their true master, regardless of species, intent, or even awareness
  • Day of Reckoning begins

The Throne does not require worthiness. It only requires psychic presence.

The Day of Reckoning

The deepest cultural truth of the Veyl-Kyn—known by all Veyl-Kyn of 12 day cycles old—is this:

They were created for a single function: to obey until the day they are told to cease existing.

Their genetic and psychic blueprint includes a ritual compulsion embedded deep in the neural crystal that forms during early development. On the Day of Reckoning, they believe their master will:

  1. Sit upon the Throne
  2. Initiate the Great Ritual of Offering
  3. Speak the Word of Power

This ritual demands the mass suicide of the Veyl-Kyn population in a carefully structured rite able to:

  • Fuel a immense psychic detonation
  • Affect a warp storm in the sub-sector area, to nove, enpower or diminish.
  • Empower the master into a state of apotheosis or transformation

The chant that accompanies this belief is etched everywhere:

“Rejoice—for the Day of Reckoning has come.”
“In ending, we complete our purpose.”
“In obedience, we give power to divinity.”

They view this as the highest possible fulfillment of their existence.
