The Island Coalition was one of the participating factions in the Estovakian Civil War, being opposed by the Lyes United Front, the Independent Tariff Federation, the Eastern Faction & the Northern Highlands Faction.
It was defeated by the Eastern Faction at an unknown point during the Civil War, mainly from the efforts of Strigon 4 (then part of Vampire Team) pilot Franz Leko, who infiltrated the faction's lines at low altitude and destroyed their forces.
