I met the Precursors for the first time.
Their fastest ships can reach over 13k km/s (mine around 8k).
My best missiles have a chance of hitting them at around 25%.
The first clash between my survey ship, and their scout (unarmed) was a stunning success.
The next clash was also stunning. The latest generation of destroyers (6 pieces of 9k tons) and a command cruiser (18k tons). It fought their two ships (22k tonnes each).
One destroyer destroyed, one in a condition that forced them to leave.
Something feels like the end of the United Nations Enclave is coming.
