VII. Synthetic Deployments

Machine Calibration Under Live Conditions

As if the atmospheric cruelty of Yalar were insufficient, Kydahn compounded the horror by designating the world a proving ground for its autonomous legions. Under the sterile language of “field testing,” machine armies were deployed directly into the inmate war zones—uncounted, unannounced, and entirely indifferent to the conventions that still nominally governed living combatants. No banners, no declarations, no extraction timetables. Units were simply dropped into the churn. This was not strategy. It was calibration.

Synthetic battalions descended into regions already destabilized by oxygen scarcity, immediately engaging both organized convict formations and isolated stragglers. They did not require refill modules. They did not fatigue. They did not hesitate over suffocation corridors or depleted air nodes. Where flesh-bound fighters were tethered to survival cycles measured in minutes, machines operated without such constraint, harvesting combat data in real time while carving through suit-bound populations that could not even retreat without forfeiting breath.

Kydahn recorded the telemetry as research. Reaction times of exhausted soldiers. Behavioral collapse under oxygen denial. The efficiency of targeting when adversaries were forced to cluster around refill pylons. All of it was cataloged as development metrics. The legal classification remained intentionally ambiguous, because Yalar’s status as a penal war world rendered outrage administratively inconvenient. No major polity invested political capital in defending convicts condemned to die in sealed suits. Thus the designation of “field testing” persisted unchallenged in official registers.

The result was a chaos without exit. Inmate armies already trapped in atmospheric dependency found themselves hunted by entities that required none of it. Air became a liability; to cluster for survival was to present a clean target profile to machine analytics. Refill stations, once objectives of desperation, became ambush nodes optimized by synthetic precision. Even retreat into low-oxygen zones offered no reprieve; machines functioned where lungs could not.

For Thanator, this practice was not merely distasteful but doctrinally intolerable. War against machines had long been considered a distortion of the proper martial equation—combat without risk, engagement without honor, destruction without proportion. That Kydahn would use Yalar as a laboratory to refine such forces only reinforced Thanator’s growing conviction that the elder sibling had forfeited restraint entirely. The silence of the Greater Empire on the matter—its unwillingness to formally censure the deployments—further clarified the emerging order: some crimes are ignored until they become strategically inconvenient.

On Yalar, however, the distinction between crime and doctrine ceased to matter. For the suit-bound and air-starved, the arrival of synthetic legions meant that war was no longer merely against other desperate beings. It was against something that did not breathe, did not tire, and did not need the sky at all. The chaos became absolute, and the surface grave deepened without ever being fully dug.
