Faint ripples began to spread across a patch of space.
Those ripples soon grew into waves.
The waves grew even further to the point where space almost folded in half!
The nearby listening beacons that were close enough to monitor the obvious gravitic fluctuations with minimal delay quickly parsed the readings and calculated that an extremely sizable fleet was transitioning into the star system.
Those tiny beacons immediately transmitted their alarming data and preliminary conclusions to a larger automated listening post.
Unlike those tiny beacons floating in space, the listening post was a more robust facility that had a lot more processing power at its disposal. Most of that was being used to double-check and confirm the preliminary conclusions.
Once its automated systems became assured that the incoming readings weren't the result of a glitch, it transmitted an alarming message through its quantum entanglement node.
