"Despite our efforts to stop our enemy's ships from entering your sector prematurely, two seem to have penetrated before your destruction of the Star Gate. These two ships have not made any aggressive moves yet, but they will, soon. Don't worry about more coming into the sector--the hyperspatial rift prevents that. Without hyperspatial travel, it would take any ship years to traverse interstellar distances, even at the speed of light. Years ago, however, we, the Ambrosian League, sent one of our ships to your sector, and it has been hiding in hyperspace ever since. It will meet you in the Risa System, where the enemy ships are located. Destroy the ship, then return to <RST>. Good luck."
