The Cathedral manifests as floating crystalline structures composed of fractured marble embedded with corrupted binary streams. Its spires pulse with the residual data of every player who faced deletion, creating a harmonic frequency that competent code readers can perceive. The interior contains infinite corridors of stored memories - competitors who enter can witness fragments of previous deathmatches. The structure grows larger with each week's culling, making it an ever-present reminder of the simulation's accumulating cost.

The Shard Cathedral serves as both warning and sanctuary within the Corrupted Codex - competitors whose code destabilizes can seek refuge within its fragment-walls, temporarily slowing their deletion. However, lingering too long draws the attention of the Cache Specter, who haunts its corridors seeking new fragments to add to the collection. The Cathedral connects all leagues by representing the one fate that transcends individual competition: complete deletion or permanent transformation.
