King Antiochus I was a Seleucid ruler who, some time before the 2nd century BC, tried and failed to conquer Byzantium after successfully conquering the nearby Chalcedon. (PROSE: Byzantium!)
Behind the scenes[]
Antiochus I was the son of Seleucus, who appeared in Farewell, Great Macedon, although this fact has not been confirmed in any known DWU fiction.
