The ridgeline offered the best vantage point.

  Aethernus Vhal covered the three kilometres from the impact site with steady, economical strides, logging terrain and biological traces with the same methodical focus he used when advancing through hostile territory. The rise, 172 metres above the surrounding landscape, provided more than visibility. It provided superior elevation, multiple avenues of withdrawal, protection from blaster fire, and defensible positions in case of engagement.

  He chose a weathered stone outcropping near the crest and settled into a low crouch. Improvised weapons and harvested materials lay within easy reach as he began a systematic evaluation.

  His helm was damaged, but not dead. Environmental analysis routines still functioned at reduced capacity. Broken, flickering runes crawled across his vision as he cycled the remaining sensors.

  Higher than Terra-standard, but within safe limits for unaugmented human respiration.

  Trace gases were detected argon, neon, methane in stable proportions indicative of a self-regulating atmosphere.

  No toxins detected or airborne pathogens. No spore-based bio-weapons detected either.

  The air carried complex scents, automatically parsed and filed by his enhanced olfactory cortex.

  No hint of warp taint.

  No chemical spoor of industrial overuse.

  Atmospheric pressure registered at 101.3 kilopascals, very close to Terra baseline.

  For ordinary humans, it meant comfortable, unaided breathing.

  For his lungs, it translated to approximately thirty-two percent more oxygen uptake capacity than required for sustained combat. An operational reserve to be exploited if necessary.

  With his armour’s inertial systems gone, he reverted to internal calibration for gravitational assessment.

  Centuries of warfare on worlds with diverse gravities had left him attuned to subtle differences, accurate to within 0.005 of Terra-standard.

  He tested the gravity. Sufficient to maintain baseline human musculoskeletal health over long periods. Low enough to confer tactical advantages. Higher leaps, reduced impact stress, quicker reactions, marginally lower energy expenditure across extended operations.

  Thermal scans of the surrounding terrain indicated broadly consistent temperatures, with minor variations tied to elevation and exposure. Vegetation patterns implied a mild, likely seasonal climate. Wind vectors and cloud movement suggested stable, cyclical weather systems rather than the chaotic storms characteristic of many death worlds. Environmentally, this planet did not present as a trial.

  It presented as an asset much like Ancient Earth had been.

  He had walked on planets whose atmospheres were chlorine and sulphur dioxide, where any unsealed exposure meant dissolution of unprotected tissue. He had fought on high-pressure worlds where the air itself crushed flesh and armour, turning ceramite shells into compact coffins and their occupants into paste. He had prosecuted campaigns on moons saturated with radiation, where minutes could kill an unaugmented human and slowly erode even his own cells.

  The False Deity’s desperate gambit, intended as exile or execution, had thrown him into a place that required no technology for humans to live upon it.

  A potential prison that doubled as a sanctuary.

  As he completed the environmental evaluation, something new intruded.

  It began as pressure behind his eyes. Very faint and similar to the onset of a psychic probe, but without the familiar corrupt resonance of the warp.

  The pressure sharpened into light. Symbols formed in his field of vision just like the runes that scrolled across his helm’s visor. Replicating the style but with a language and letters he had never seen before. Unlike the runes he was used to, they did not appear on his helm’s display as his fractured overlays remained unchanged. Instead, the runes hung in space before him, luminous and insistent. Beyond the encasement of metal around his head.

  They were neither the clean, angular glyphs of Imperial data-script nor the writhing, blasphemous sigils of Chaos.

  They were strange shapes that shifted in their floating positions within the air. Folding upon themselves and recombining in constant flux.

  Aethernus Vhal remained still without understanding the proper protocols or path to dealing with something like this..

  Yet, his muscles remained taunt and mind observing for any danger.

  The phenomenon did not follow the error patterns of failing hardware either. It interacted with the environment, casting faint shadows across nearby stone, refracting light as though partially real. Yet, something within him didn't have a shadow of doubt that only he could see them. This was a localized event that only he could witness for the time being, as strange as that sounded.

  The symbols began to stabilise into patterns that resembled language, though it wasn't High Gothic, Mechanicus Cant, Chaos bastardizations of them, nor any xenos tongue in his extensive catalogue.

  Despite this, meaning arrived within his brain. Directly implanted against his will.

  Error…

  Classification Failure

  Anomaly Detected.

  The line persisted for 3.7 seconds.

  Then it changed as though it had been trying to study him. Yet, Aethernus Vhal did not feel anything untoward.

  Parameter Mismatch…

  Recalibrating

  The manifestation expanded. Symbols arranged themselves into a circular array around his position. Each rune pulsed with its own rhythm; the overlaps produced interference lattices, patterns of light and force that reminded him less of scanners and more of structures from theoretical physics. It didn't feel like augur arrays. It didn't feel like sorcerous divination. It felt as if reality itself were attempting to measure him, to resolve him into a known category.

  Subject Exceeds Measurement Thresholds

  Initiating Secondary Classification Protocols

  This book's true home is on another platform. Check it out there for the real experience.

  He watched with mounting interest. Aethernus Vhal hadn’t seen anything that found his fancy and did not attempt to sheer his head off in a long time. Probably before he started his Endless War against the warp and chaos in totality.

  The process read and studied him as response, but it did not leave any indicators that it intended to attack. It felt like an automated process rather than directed. It evoked the image of Mechanicus classification subprocesses and explorator machine spirits attempting to index unknown artefacts, but at a scale that suggested planetary infrastructure.

  New symbols appeared, forming matrices that looked like visualisations of quantum calculations.

  Threat Assessment… Error…

  …Inconclusive

  Biological Profile Contradictory

  Energy Signature Nonstandard

  The system, whatever it was, struggled.

  Each attempt to classify him triggered new contradictions, new error states, new branches in its analysis, and more confusing notifications and messages. It was growing irritating at this point. Thankfully, the cycle began to accelerate. Symbols appeared and collapsed too quickly for normal perception; even with his enhancements, they blurred into streaks of light and pressure.

  It took a second before a stable message resolved itself before him in the air.

  Attempt 37… Recalibration Failed

  Adaptive Protocols Engaged

  Anomaly Containment Measures Suspended

  Thirty-seven attempts logged, then a shift from fixed classification to adaptation just like he had seen the monsters do without hesitation.

  ‘’ merited its own internal flag.

  The system had identified him as alien to its normal fauna and it potentially possessed containment protocols for beings like him.

  Yet, it had chosen not to deploy them.

  The ring of symbols pulsed once more with another string of messages.

  Then the array collapsed into a single floating glyph at eye level.

  Observation Protocols Initiated…

  The symbol’s glow faded gradually.

  A subtle distortion in the air lingered for several seconds, then dissipated entirely.

  Aethernus Vhal hadn't moved an inch ever since this kicked off.

  He stored every detail.

  The manifestation matched no known Imperial technology, xenos system, machanicus foolery, or warp phenomenon in his operational memory. Yet, it lacked the malice and psychic abrasion typical of the warp and much of all the others including that of the Imperial Technologies. For as honorable and powerful his juggernaut brothers were, they didn't suffer a pleasant existence. It also lacked the hostility embedded in most non-human scanning architectures.

  Whatever monitored this world, whether advanced, nature-integrated technology or something that resisted existing classifications, had attempted to measure him.

  It had failed. And, after failing, it had fallen back from containment to observation.

  That distinction was critical.

  This system recognised that he didn't fit its parameters. It either could not, or would not, respond with direct hostility.

  He assigned the event highest priority in his tactical database. A world capable of altering itself to accommodate his presence, and of attempting to quantify him by manipulating the fabric of perception, represented both opportunity and threat. The absence of immediate aggression didn't equate to safety. Only a fool would ever fall for such twisted lies and false promise of inherent safety.

  It indicated a different threat model thats all.

  One that warranted caution though not any action for the moment.

  The hunt would continue as always, but with greater care..

  Time passed, measured in slow changes of light and wind rather than in incoming fire or shifting battle lines. When he finally rose from the outcropping, the world remained the same on the surface, quiet and stable, but his path through it had changed. He had reached the ridgeline and surveyed the surroundings.

  The world lay before him like a tactical overlay, even without functioning targeters.

  Aethernus Vhal’s augmented sight broke the landscape into gradients of advantage and risk, lines of approach, choke points, fields of fire, blind ground. Vegetation density, elevation shifts, potential ambush sites. It was all sorted, ranked, processed for strategy, and then filed with the same cold efficiency he had applied across a thousand campaigns.

  The ridgeline remained the best vantage in the direct vicinity.

  He held that position as the helm’s damaged senses strained to harvest useful data from the environment.

  When he turned his attention to the southeastern quadrant, his helm systems flickered, struggling to maintain coherence. Amid natural thermal drift, a pattern emerged, regular heat signatures roughly 7.3 kilometres distant. Too structured for geological phenomena, too ordered for random fauna.

  Built forms with distinct movement patterns. It also had energy emissions that were all consistent with an inhabited site.

  He logged the observation as he would enemy troop movements.

  The thermal bloom outlined structures buried beneath the canopy, nestled in a shallow valley. No sharp spikes indicative of plasma reactors or void shield generators. Unlike Imperial colonies or corrupted strongholds, this installation radiated a steady, low-intensity power signature.

  More advanced than primitive, but less than interstellar. Standard doctrine dictated prolonged observation prior to contact. All to figure out determined force strength, defence capabilities, technological base and social structure. Then engage, or erase. Standard doctrine also assumed support. Whether it be orbital overwatch, vox networks, reinforcement routes, or extraction contingencies.

  He had none of these and hadn’t dealt with any such standard doctrine for centuries if not a thousand years already.

  He usually found himself alone on unknown worlds and within an unknown strategic framework as had always been within the warp.

  Information wouldn't come to him. He would have to go to it.

  Aethernus Vhal weighed the options with precision.

  The need for reliable information outweighed the comfort of concealment.

  Aethernus Vhal moved forward.

  The crude armour of bone and hide, harvested from native predators, shifted against still-healing skin. Shards of crystal from the apex creature hung at his flank, rough but serviceable as interim blades. His body, though recovering from orbital descent and subsequent combat, operated at approximately eighty-seven percent of peak capability.

  More than sufficient for reconnaissance-in-force.

  He descended the ridgeline with controlled precision.

  Each step optimised for balance, readiness, and minimal energy expenditure. His feet found purchase on loose scree and weathered stone without sending debris cascading downslope. Where a baseline human would have produced a rattle of falling rock, he moved like water through existing channels.

  The treeline rose to meet him.

  At the forest’s edge, the undergrowth grew thick and tangled. Brambles, low branches, tree trunks, and dense shrubs formed an organic barrier that should have impeded even his strength, if only through the need to break and shove.

  It did not.

  Aethernus Vhal could feel the pervasive observation of the world’s strange system and floating words crawl up his back. It made it feel like the trees, or something within them, were watching. But he was no fool. The trees themselves could do no such thing. It was that strange energy behind the floating words that tried to emulate his helm’s reports as though to trick him.

  He advanced regardless of what he thought about the matter. His awareness extended in all directions, tracking potential angles of attack, cover options, and movement paths. His damaged helm senses remained useful, if limited. They still registered the heat blooms of nearby creatures.

  Predators maintained distance as per his latest report.

  Their signatures clustered no closer than two kilometres, bodies running hotter than baseline patterns. Alert and aware of his presence. Yet, them choosing not to close.

  Prey species moved with relative normalcy.

  Small forms darted from cover to cover, their patterns suggesting wariness but it wasn't immediate panic.

  They didn't yet consider him an active threat anymore.

  That same feeling behind his eyes returned with vigor the closer he moved toward the cluster of intelligent beings and civilization. Again it lacked hostile intent of targeting systems and the corrosive psychic drag of warp scrutiny. It felt more like the assessment of a quartermaster inspecting unfamiliar equipment and uninterested in anything but function.

  The pressure grew worse as he crossed a narrow stream.

  Water flowed around his legs and up to his hips. Fish and larger aqua-creatures swam along without bothering him. Some approached out of curiosity.

  For 2.3 seconds, the pressure peaked, resolving into an almost tactile sense of contact.

  There was no intrusion or an attack on his mind.

  Then it faded, subsiding to a background weight.

  He continued toward the settlement, moving through the forest with the same relentless purpose that had carried him across centuries of war. Animals continued to avoid him. The steady pressure within his mind fluctuated in intensity but never vanished entirely.

  At roughly halfway to the target, the forest began to thin.

  His degraded helm senses resolved more complex thermal structures ahead. Linear heat differentials marking roads, colder lines hinting at irrigation channels, and broad, evenly patterned plots consistent with cultivated fields.

  The settlement was larger than initial returns had suggested. He adjusted population estimates upward, likely several thousand at minimum.

  Significant enough to support a functioning society.

  Insufficient, by initial estimate, to field major standing armies. He halted at the edge of a clearing to review the tactical picture. Mission parameters remained self-imposed and absolute.

  Gather information. Identify threats. Determine operational status and potential objectives. No command directives. No formal briefing.

  Duty did not require those once he stripped himself of the Imperium of Man and started his Endless War.

  The pressure behind his eyes surged once again. His vision greyed for a second, then all of his bodily functions kicked into overdrive and forcefully snapped his vision back.

  New data slid into focus.

  Subtle energy came from the direction of the settlement that fit the pattern of the earlier manifestations.

  As though it had already observed and classified every single individual within the settlement and categorized them into whatever system it had.

  Successful with them what it had failed with him.

  Aethernus Vhal frowned, but resumed his advance anyway.

  All his senses were primed and every muscle ready.

  His war would continue. The target remained undefined.
