In the Sea Emperor Star Realm, there are seven administrative stars, with a total population of around a hundred billion.
In terms of location, the Sea Emperor Star Realm is adjacent to the Twelve Star Domain. However, the Sea Emperor Star Realm has a large number of Caucasians. Although Huaxia culture is still mainstream, it is vastly different from the culture of the Twelve Star Domain.
This is entirely normal.
In the past, transportation was inconvenient, and dialects varied within just ten miles. Beyond a hundred miles, customs and practices were entirely different.

Over thousands of years, even the Alliance's enforced unified elementary and secondary education could not stop the trend of division among various Star Realms.
