The frontier fortress built by Eve and specially suppressed by Meiruier, the Black Dragon King, has changed a lot since it was established more than ten years ago.
The former fortress has been expanded three times, three floors inside and three floors outside, which looks like a black magic palace.
In the fortress, there is the gate of hell, the gateway to the world of Saigus, while outside the fortress, a large main city has been built.
It was a city that players spontaneously built. Seven years ago, it officially passed the official certification and became one of the official main cities, an important player stronghold in the first layer of hell
