At some point prior to the Lighthouse War, Roald joined and served in the Erusean Air Force after being invited by his friend Hermann. At the onset of the war, he was tasked with guarding Mihaly A. Shilage on his combat sorties as a member of the Erusean Air Force's Sol Squadron.
On September 19, 2019, Sol Squadron was sent to provide back up for the Erusean Army, which was beginning to falter at Farbanti. Hermann and the Sol Squadron engaged Cyclops and Strider Squadrons over Farbanti. During the fight, Sol 1 and the rest of his squadron retreated when the Usean satellite system went offline.
As various nations in Erusea began declaring their independence, Roald and the squadron resided in Shilage. On October 24, 2019, they took off from a tunnel to defend Shilage Castle from an attack by Strider Squadron. Roald was shot down, where he ejected and deployed his parachute.
