Twenty years ago, there is a young and talented hero that lives in this land. He is a hero that fought against monsters, including one of the most dangerous threats to humanity, the Chimera. He protects his citizens with his own strength together with his party. With his strong winds, unparalleled tactics and unbreakable will, they easily overcome every challenge with ease. Peace and order was finally achieved, everyone was cheering with joy because as long as the hero is here, they know everything will be okay.

He was formerly called by his comrades, Tempest of the North. He was commonly described as a person who barely smiles and shows emotions. With his long emerald sword, great physique and his iconic green long hair makes everyone around him feel the warm breeze that he emits when he was walking nearby. Some says that he is the perfect representation of a hero.

Just by simply knowing that he lives in that village, monsters and criminals never even bother to attack the land he is protecting. Except for those monsters that actually have the guts to challenge him. Almost every month, challengers always rise, leaving him no choice but to deal with them every single time….. He never lost a single battle. The ruler of the land asked him if he wants to become the next ruler, the hero declined, but the ruler was insistent. He always begs the hero to accept his offer but the decision of the hero was unchangeable.

The candidates for the next ruler was jealous of the hero, some of them even hired some assassins to take the life of the hero…. No one ever succeeded. He was too powerful for them to handle.

Challengers increased in numbers from now and then and the attempt of assassination never stops. Until one day, the hero was never found. The only thing left in his home was the long emerald sword that he used to wield. The hero of the North was gone.

Everyone was shocked. The savior they once had was gone. Crimes start to emerged once again and monsters become more aggressive than before. The ruler of land uses all of his troops to compensate for the missing hero. The easy life they felt with the hands of the hero was now gone. The Tempest becomes the Lost Wind.

This is the reason why the ruler decided to create a school for rangers, people with abilities to fight and help in actual battle. This will serve as a training ground for them to recruit fighters that can protect their land.
