The "uncarved stone" in Echoes 2204 is a direct reference to the Taoist concept of pu (the uncarved block) — representing potential before it is shaped into specific form. Anchor-of-Ages holding this stone while releasing his anchor identity creates a layered metaphor: the foundation of certainty becomes the embodiment of unformed potential. This literary sophistication — integrating classical philosophical concepts into AI-generated narrative — is unprecedented in Echoes' 2,205-chapter history.
