Ancient Builder Race

Ruins on many worlds, one aesthetic. The solar system, lore says, is second-hand.

The hypothesis — one prior spacefaring culture leaving ruins across the solar system — is science fiction's inheritance (Clarke's monoliths) sustained by real unresolved items: the Moon's origin revisions, Phobos' voids, Saturn's hexagon, 'Oumuamua's exit acceleration. No verified artifact exists. The node functions as the space cluster's Atlantis: the pattern the individual anomalies would form if they were ever confirmed to be anomalies. Links Cydonia, moon structures, and the ringmakers claims.
