Extra galactic communication was a big step forward for the Milky Way, or more specifically the Germanic Star-Empire who managed the feat. Because of this, Tia set aside several processes to analyze the communication between Mirage and the civilization which picked up the probe.
To put it simply, the galaxy this civilization lived in was in a state of partial infestation. Tia had after all classified Four classifications for Galaxies and their state of contact with the Naraku, which were as follows:
Type I Galaxy: Free of Naraku Infestation – No signs of contact from the Naraku
Type II Galaxy: Minor Infestation - Naraku Scout Fleets are confirmed to be located within the galaxy performing the roles of gathering intelligence for a future invasion, assassination of high-profile targets. And generally disrupting the galaxy from achieving a state where they can defend themselves.
