Ian Davion (b. 2980 – d. October 21st 3013; see also Notes) was the eldest son of Andrew Davion, and ruled the Federated Suns from 2999 until his death during the Third Battle of Mallory's World in 3013 at the hands of Yorinaga Kurita. Known as "The Hound", he preferred combat to politics and did not care much for statecraft. Because he had no wife or children, he was succeeded as First Prince of the Federated Suns by his younger brother Hanse Davion.
Ian Davion piloted an Atlas at the time of his death.
