The Structural Sage emerged from the collective wisdom of early Reality Anchors who documented successful reconstruction techniques during the first void incursions. As knowledge crystallized into living wisdom, this sage became the repository of all structural principles that have proven effective against entropic dissolution. Astra Vale's meticulous study of ancient course maps contributed significantly to the sage's accumulated understanding of geometric stability.

The Structural Sage manifests as a luminous geometric humanoid composed of interlocking golden triangles and reinforcement lines that pulse with accumulated knowledge. Its form remains perfectly stable and complete, never showing signs of dissolution or entropy, embodying the Anchor Wardens' commitment to permanence. When activated, the sage projects holographic blueprints and structural diagrams that reveal optimal anchoring points and reconstruction strategies. Its presence strengthens nearby reality anchors through harmonic resonance patterns that reinforce geometric stability.

The Structural Sage serves as the primary knowledge repository and strategic advisor for Reality Anchors engaged in reconstruction efforts. It influences events by providing tactical wisdom that improves anchoring effectiveness and coordinates multiple players' stabilization attempts through shared geometric understanding.
