According to Arkadian history, after the total destruction of the other half of the Arkadian Binary system, the survivors towed one of the last remaining moons over to the smoke ring surrounding the other star.  They renamed it Antigonia, after their destroyed homeworld, and in the last two thousand years it has become the center of civilization in the Arkadian Ring.  It is also the place where we found a very special artifact that we had been searching for.
