In the beginning, King Hwanungcheon came down to Taebaeksan Mountain with three goblins and founded the country. However, there was a goblin who was not called except for 3 goblins. To the goblin, Hwanung ordered him to develop his strength in preparation for the war and he worked hard to cultivate his strength. Then a war broke out and he gave his life to burn the flame to save Hwanung who was attacked by enemies. Hwanung, who felt pity for him, brought him back by the power of God, and he could not live in the same world, so Lost Saga was sent to the world. It is a close-range mercenary that turns into a goblin fire and attacks it after a quick maneuver, a saltfire that makes it a flame to the target hitting itself, a earthenware that summons a small fire goblin to launch a self-destruct attack on an enemy, and a Pungbi Park that swings a gold blockade to strike multiple enemies.
