Following multiple rounds of negotiation, the Roya and the Polar Collective reached an agreement to jointly construct scientific facilities around three key sites: the Exostrider’s greatsword on the frostlands, Sundermere in the underground cavern, and the Etching Plains.
The Solisylum provided critical data on the Reactor Drive’s operational cycles and Void Storm zone metrics, enabling large-scale infrastructure planning. Concurrently, Royan Shepherds coordinated the Exoswarm in excavation, transport, and logistical support, ensuring the project’s contiunous advancement.
Through this cooperation, the Polar Collective completed the first phase of its expansion: the Frostlands Polar Research Outpost, followed by the completion of the Starward Riseway, a massive vertical transport elevator constructed directly on the Exostrider’s greatsword.
At the same time, the New Federation contributed its most advanced spatial-engineering technology to construct the Spacetrek Research Institute. This ring-shaped facility operates within a local low-gravity band, maintaining a stable orbital trajectory to perform continuous scans and deep-range probing of the greatsword left behind by the Exostrider.
Based on extensive non-invasive analysis of the Exostrider and Exoswarm, combined with data provided by the Roya, the Polar Collective has reached the following conclusion:
The Exostrider exhibits extremely high biological homology with the Sentinel, yet its functional profile is sharply divergent. It lacks the Sentinel’s cognitive capacity for prophetic insight and civilization guidance.
Its strengths lie instead in specialized combat capabilities, exceptional mobility, and pronounced biomechanical adaptability. From these traits, researchers propose the hypothesis that the Exostrider is a ████ within the ████ system, fulfilling the roles of transportation and warfare. To distinguish the two, the Institute formally designates the Exostrider as a “Sentinel Analog”
Under exposure to and catalysis from the Reactor Drive, components detached from the Exostrider’s body differentiate into two classes of Exoswarm entities: animal-type and plant-type. These unique lifeforms replace the extinct fauna and flora of Lahai-Roi, stabilizing and supporting its fragile ecosystem. When sufficiently fed or charged, the Exoswarm return to the Exostrider and fuse back into its frame, repairing damaged section.
However, long-term Royan records on the Exoswarm differentiation and generational cycling reveal that this bio-mechanical restoration process is finite. Like human cells, the Exoswarm possess and upper limit to their number of divisions. Over time, regeneration intervals lengthen, the rate of new differentiation decays, and eventually the process will stop completely.
Our projections are even more concerning. Calculations show that the total number of Exoswarm units that have already been reabsorbed, combined with the maximum potential yield from future differentiation, is still insufficient to achieve the Exostrider’s Complete
Further investigations and energy-level diagnostics conducted within the underground haven of Lahai-Roi confirm that, even in a dormant state, the Exostrider continues to fulfill an instinctive, self-regulating drive to safeguard both the region and the Roya.
Survey data indicate that not all components detach from the Exostrider differentiate into sentient Exoswarm units. A significant portion instead transmutes into bionic structural formations embedded within the geological strata. Branching and interlocking like vertebrae, these formations are now classified as Subcrust Spines. Distributed uniformly across unstable tectonic zones, they are hypothesized to play a crucial role in maintaining crustal integrity and channeling energy derived from the Reactor Drive.

Additional analysis reveals that the Exostrider’s energy-generating nucleus, the reactor Drive, and its physical chassis represent two distinct tiers of creation.
