Almost all sailors like to deal with the Rosa People.
Like the Angsak Kingdom, the Rosa Kingdom is also a relatively wealthy maritime nation.
The Angsak Kingdom has close ties with the commercial union of White Oak Main Island, and the Royal Family makes a fortune by monopolizing the Refined Sunshine, while the Rosa Kingdom enjoys the dividends of Age of Exploration trade routes.
This can be attributed to the geographical location of the Rosa Kingdom. Rosa Island is close to the Fortress Main Island of the Alliance, both located in the southernmost part of the world.
Since the Alliance has been searching for a new world beyond the Chaos Sea, the sailors on the Fortress Main Island are all experienced in route exploration, and at the Governor's call, the local citizens devote almost all their efforts to the Forbidden Route in the Extreme South Sea.
