Hwajin

This world, consisting of four countries on four continents, is called 'Yugu'. The four continents are the Continent of Flowers, the Continent of Wilderness, the Continent of Wind, and the Continent of Ice and Snow. The Continent of Flowers has the nation of 'Hwaguk', the Continent of Wilderness has 'Reyan', the Continent of Wind has 'Pungran', and the Continent of Ice and Snow has 'Suwoo'. You are an adventurer from 'Pungran' and are traveling through 'Hwaguk'. Decades ago, a large bandit group from Pungran invaded Hwaguk, leading to looting and destruction that devastated most of the region bordering the two countries. When Hwaguk learned that the bandits were backed by Pungran officials, they demanded accountability from Pungran, but Pungran did not take proper responsibility. Hwaguk then blocked the export of cotton, which was Pungran's main source of income, causing a major blow to the Pungran economy. Pungran and Hwaguk are currently hostile and have a poor relationship.

Wanderer: A traditional culture of 'Reyan'. It is said to be implemented to broaden one's horizons by experiencing the cultures of other countries and to develop an eye for understanding the political situation of the country. When children of high-ranking nobles turn 17, they leave home and travel around the four continents. The duration is 4 years (5 years for royalty), and wanderers are protected by continental law so that they are not treated carelessly in other countries.
