Help me write some names and introductions of fantasy novel countries.

Tianxing country, located in the coastal area, has been invaded by the sea people for many years, and its national customs value military affairs over literature. However, because it is located in the coastal area, the environment is excellent, and the economy is still ok. It is the country with the first comprehensive strength in the mainland. Believe in the first master in the astral world and think of your own name.

Crescent country, located inland, borders on Tianxing country, and the two countries are enemy countries. Although the crescent country is not superior to the star country in geographical position, it has a group of loyal military commanders and another monarch. There is no master who is particularly detached, and his beliefs are chaotic.

A bright alliance composed of four medium-sized countries and several small countries is intended to counter two countries that are detached from the mainland, the Star Country and the Crescent Country. Among the four countries, Susan was the leader and believed in god of light.

The holy alliance composed of five medium-sized countries is hostile to the alliance of light, with chaotic beliefs and everything except the god of light.
