Guildenstern was a general in the Detinan Army during the Detinan Civil War. He commanded the Southron forces which took possession of the city of Rising Rock, Franklin Province and compelled the locals to throw him a parade. He then led his army north into Peachtree Province to continue their campaign against the Army of Franklin. Guildenstern led his forces to the River of Death, where they were defeated and nearly routed. Count Thraxton the Braggart pursued Guildenstern south and besieged his army in Rising Rock. After the Army was relieved by other Southron forces, Guildenstern was relieved of command and sent to the eastern frontier. His role in the war was over.
