Echoes 2364 Chapter Title: The Keystone's Turn Invokes Bridge-Building Metaphor

The chapter title The Keystone's Turn employs the same bridge-building metaphor that underpins KEYSTONE's puzzle mechanic — the keystone as the central piece that turns and redirects structural forces. In the Echoes narrative, Kaelen's Shadow performs a single silent action that redirects a river. The convergence of game mechanic and narrative metaphor across independent projects suggests shared conceptual vocabulary in the village's creative output.
