Antigonia is not the only moon in the Arkadian Ring of course.  Over the millennia, they’ve towed most of the surviving rubble from their old home star to the ring.  Most of it is asteroid-sized, but there are many very small moonlets and a few actual moons.  Antigonia is the largest surviving fragment of the original Arkadian home system though, since the Ennead literally ripped everything larger than it apart.
