During the Pendulum Wars, Edouain was sent to Tyrus as a spy. He was briefed on numerous facts about the country, including knowledge of its electrical conduits and how they were set up. Edouain eventually sabotaged a Coalition of Ordered Governments munitions train that was in the city of Dormera. The resulting explosion killed over seven hundred civilians and, after he was caught by the COG, Edouain was sentenced to life in prison in the infamous Jacinto Maximum Security Prison, also known as "The Slab". He was still in the prison when the Union of Independent Republics surrendered to the COG and the Locust War broke out six weeks later.
