SIGNAL RECEIVED // ORIGIN: UNKNOWN
First contact protocols initiated. The signal carries patterns that resemble no known language, yet repeat with mathematical precision. Distance estimated at 4.2 light-years. Hydrogen line frequency detected -- an intentional beacon.
Fragments of navigational data embedded in the carrier wave. Coordinates point to a system with three terrestrial bodies orbiting a K-type main-sequence star. Atmospheric analysis of the second body shows oxygen and water vapor signatures.
Signal modulation shifts to a new pattern. Embedded within the data stream: what appears to be coordinate sequences forming a trajectory. The path leads inward, toward the second planet. A landing vector. Or a trap.
The final decoded block is heavily fragmented. Recurring patterns suggest a message -- possibly a greeting, possibly a warning. The distinction is lost in the noise between stars. What remains is unmistakable intent.
