The Iron Circle is a an old custom that was popularized by Silenius au Lune .
One would fly their shuttle without escort in a ring around a planet or moon upon their arrival, regardless of political tensions or adversaries at large as a sign of dominance.
The custom was dropped by some families due to many powerful people being killed during the flight, often being shot down.
Virginia au Augustus performed this custom in Dark Age, when arriving on Mars after escaping Luna at the hands of Lilath and the Abomination .
