Duck The signal didn't go un-noticed, as evidenced by the sudden appearances of various, semmingly not connected visitors. And once more, another of them appeared, just after one of the other crafts left subspace (HarryRocks101 ).
A bridge opened, bringing a very distant star, that sat dozen of lightyears away. Between the star and the station's star system, from which the call departed, space seemed crushed and folded, several times over, visually distorting any objects that happened to be in it's line of sight. The anomaly occured only for a brief moment, and then stopped existing, leaving a medium sized spacecraft behind.
The starship that followed was of angular and compact design, covered by reflective rainbow-like colored armour. It's surface was mostly smooth and no turrets or similar systems were visible from the outside. It was likely to be a scout ship, made to investigate events like this, and learn of their origin. Luckly, due to a recent incident, the senders of the craft were able to construct a biological machine, which they promptly placed onboard of this vessel and sent for testing. After this ship quickly stationed itself to a relatively motionless position according the station, it proceeds to make a detailed scan of it, as well as of the other unknown ship that entered this area.
