Stellaris: My Hometown Is Always Invaded After I Go to Space

Human beings have spread all over the solar system, and from that day onwards the idea of ​​moving was born. Countless strange things in the universe appear in the solar system, including alien invasions from next door, unknown fleets sent by space-time storms, biological civilizations arriving through wormholes from unknown galaxies, visits from human civilizations from other universes... These nameless invaders come uninvited. They wreak havoc in our cities and lands, and then disappear as suddenly as they appeared out of thin air. We thought it was just an accident, but the invasion got out of hand. They come again and again, becoming more and more ferocious.
