Leon Oliver was a human Insurrectionist. Born on Eridanus II in 2492 to a displaced citizen of Far Isle and an Eridanian native, Oliver joined the Colonial Militia in 2509 as a temporary job to do until he figured out what he wanted to do with his life. On June 8th, 2514, Oliver and forty seven other rebel prisoners were brought to Teribus Island and executed. In 2524, during an Insurrectionist expedition to the island, Oliver's heavily degraded field cap was found and used as evidence by Colonel Watts as proof of the executions.
