The parasite is a very insidious creature that cannot be detected by station defenses. Its radar singularity resembles frozen debris or wreckage commonly found around any station. This allows it to approach the station undetected, attach itself to the hull, and use highly concentrated acid to burrow through the station's outer shell.
This process takes 24-48 hours, after which the hole is sealed, and using tentacles, it gradually stealthily captures and devours the station's crew. After burrowing into the ventilation system, spores are released, which carry Disease X.
Its presence induces hopelessness on the station. People cannot move safely through the station, causing all production and refining activities to cease.
The parasite cannot be detected from inside the station. The station must be orbited by a spacecraft, and if found, it should be shot down.
