Gavan Coalition (concept)
The Gavan Coalition was a Pirate Armada that briefly held complete control over the Pirate Coast at the beginning of the 11th Century. Lead by Captain Gavan "Iron Eye," the Gavan Coalition at its height would consist of over 90 ships and 8,000 pirates. They brutally enacted tolls and raids across the seas for nearly 10 years before their complete collapse following Iron Eye's death during the Siege of Ufaliracci.
