Speaking from a historical perspective, the city of Vielonna reached its current scale in the mid-late era of the sixth century.
Initially, when the Titan Empire's Morisette Dynasty had just completed the handover from the old to the new, Vielonna was only an ordinary small town in the south. However, after the Gaul people of the Kingdom of Faran grew stronger with each passing day, the prince of Titan, who was responsible for the defenses of the south, thoroughly changed the appearance of the small town. This member of the Imperial Household constructed the presently-called old city walls, built pillboxes and introduced a great number of local nobles to grow in Vielonna.
