Rogue Fleets (ISW Rogues Add-on) - 

    At the end of the first Interstellar War, many warfleets were left adrift
after the governments that controlled them were destroyed. In many cases,
these derelicts were taken over by pirates, mercenaries, and criminal 
syndiactes with a vested interest in galactic anarchy and disorder. These 
fleets now prowl the spaceways, attacking worlds which have come under the
control of some organized government.

    Rogue fleets will appear on radar like any others. Their purpose is not
conquest, but destruction - they will destroy defending ships, radar 
installations, and star fortresses, as well as attacking the planet itself,
reducing industry and habitability levels and killing off your population.
Fortunately, rogue fleets are usually quite rare.

    On radar scans, Rogues fleets will show up as originating from "???".
