Non-Human Signal Sources spawn primarily in the vicinity of the Pleiades Nebula, such as in the system Pleiades Sector IR-W d1-55. They are fairly common and easy to locate within this region. Other locations include systems with stations that have been recently damaged or repairing, and potential targets for Thargoid attacks that have been identified by Eagle Eye.

Threat Level

Depending on the Threat Level of a Non-Human Signal Source, one of a number of different scenarios will occur.
