Humans—and a handful of other species—who have been altered by prolonged exposure to raw echo-data, developing an intuitive ability to read and sometimes influence resonant patterns, though the process often leaves them neurologically scarred or addicted.
Echo-Touch is not a gift; it is a mutation born from direct neural exposure to unfiltered FTL resonance. It happens by accident (deep-space survivors, listening array technicians exposed to a cascade, echo-skimmer crews breathing contaminated recycled air) and by deliberate cultivation (the Undertow Syndicate's ritual initiations, black-market resonant implants).
The Gift:
Echo-Touched individuals develop a quasi-psychic sensitivity to jump-patterns. They can feel when a ship is near by detecting its resonant disturbance, sense the "flavor" of a particular space-lane's echoes, and sometimes—with training or implants—nudge weak signals into clarity or muddy strong ones with interference.
The Cost:
The Resonance Plague spreads through Echo-Touched communities. Victims experience increasing merger between their consciousness and FTL patterns, hearing phantom jump-corridors, losing the ability to distinguish between their own thoughts and the echoes they perceive. The afflicted become living transmitters, broadcasting their neural activity as false or corrupted echo-signals.
