It sits on the Azurial River. It is a planned complex, with nearby hillsides and sits near the ocean. It has a large road network which is highly connected and integrated into the terrain of Blue. Its population is estimated to be around 1 million, however, the outer cities and suburbs contain more people.

History
It was founded in 255 PB, and started as a small trading outpost, but grew rapidly shortly after. In 13 AB, it was declared the capital of the province "Northern Azurial" in Balderlanes Empire, it had grown to a large town by now.

Later, in 35 A.B.E, it was sieged by an invading force. It held out for 2 months and was later saved by the Grand Blue Army.

In 500 A.B.E, it was made the official capital after The Revolution which founded the modern Blue Government: The United Blue Republic.

Becoming a Capital City
It has historically been designated a good capital city due to its protective hills to the south, and near oceans by the North, West, and East, making it a safe and secure location, it was also made a capital city due to its vast road network from its trading outpost origins. Which made it easy to get to.

These vast road networks made it easy for people to come in and out, making it easier for it to function as a capital city.
