The Iron Corsairs are an organization of mercenaries formed in 98 A.E. when Sere Umox, second-in-command in the Free Fleet under Liao Harris mutinied, taking half the Fleet with him.
In 318 A.E. the Iron Corsairs skirmished with the Free Fleet, near the Carnine Nebula. The Free Fleet won the day, and a tentative cease-fire was agreed upon.
In 422 A.E. the Free Fleet was hired by Temejin Corp - a Shen megacorp, to blockade a remote planet under Selassian Hierarchy control. Once the Fleet was on duty and far from a Voidgate, the Iron Corsairs emerged from a nearby asteroid belt and completely wiped out the Free Fleet.
