This mercenary fortress was built with the assistance of Muse City following the Gate Rune War. Viktor served as the leader of the soldiers stationed there with Flik serving as his second-in-command.
Located in eastern Muse Principality, the fortress is surrounded by forest to the east and west. The flag which waved proudly over the fortress was designed by Viktor. Its soldiers were known for their skill and tenacity in battle.
However, the fortress would fall early in the Dunan Unification War to the onslaught of the Highland Army under Luca Blight. Viktor was able to delay the fortress' occupation by setting it ablaze. It would be occupied by the New State Army late in the war after troops were moved there in order to divide the attention of the Highland Army.
In a sense, the officers of the Mercenary Fortress could be considered the forbearers to the New State Army.
