Galactic Era, 221, January 15
Azure Star, Red Arrow Empire, Erga City, Erga Coast.
As the southernmost city of the Empire, Erga was considered a rising star. The Empire's soldiers liberated the city in 154, driving the Frost Plated People to the other side of the strait.
Since then, Frost Plated had no chance to challenge the Red Arrow. With natural barriers, it no longer posed a threat to the capital of Red Arrow.
For the Empire's aggressive expansion model, if the war did not achieve its goal, the occupation of cities was called liberation; conquering a nation was called conquest.
Apart from being militarily separated from Frost Plated by the sea, Erga, located at the southernmost end of the Empire, might have contributed to Red Arrow the most by changing the lyrics of the national anthem. After that, there were no other well-known aspects.
