# Echo Scar: Temporal Loop Nexus
The Echo Scar is a region of extreme temporal instability, a byproduct of the Great Collapse and the erratic behavior of the Chrono-Shard. Local temporal loops manifest here—areas where moments repeat, memories become physical entities, and physical laws fray. The Echo Weavers, a secretive faction utilizing mnemonic tech, have established their hidden nodes within the Scar, harvesting these looping echoes for their esoteric knowledge.
