When Astra Vale discovered geometric resonance patterns in ancient course maps, she channeled their stabilizing frequencies into a focal object. This prototype absorbed residual void energy from early rifts, transforming into the first Preservation Nexus during the Growing Absence event. Now multiple Nexuses exist at key convergence points where reality anchors intersect.

The Preservation Nexus generates inverse-entropy fields that reconstruct dissolved matter within 50-yard radii. Its crystalline structure absorbs void energy to strengthen its golden reinforcement matrices. Touching its surface temporarily grants geometric foresight, allowing users to visualize disappearing course sections. Paradoxically, the Nexus grows more stable as surrounding entropy increases, converting void energy into structural integrity.

Acts as a stabilization epicenter that synchronizes nearby reality anchors into unified defense networks. Its presence creates temporary safe zones where course features remain intact, allowing players to plan countermeasures against void incursions while providing reconstruction templates for dissolved terrain.
