In 1422, the Trunk Empire, the northern overlord of the Eastern Continent, annexed the six northwest countries and went south to conquer, provoking a continental war. In 1431, the war spread to the southern continent. In 1438, Hongfalik, a small country in the southwest of the Southern Continent, was destroyed. The remaining royal family was forced to flee to the deep sea and landed in the Western Continent. In 1443, they conquered various local races and massacred the elves and half-elves. This angered the Deldan Federation, the power of the Northern Continent, and started another all-out war in the mortal world. In 1449, three generations of dragon gods were ordered to quell the war in the mortal world. In the same year, the fallen angel Bathrines unified the demon world, assimilated the three demon kings into one body, broke through the seal, swallowed the dragon god Baia who had neglected to guard against him, transformed into a dragon demon, and led the demon army to invade the mortal world again.
In 1450 AD, the gods and dragons sent troops to support the mortal world against the demon army, and the second holy war broke out completely. Since humans and elves can already use advanced magic, the absolute advantage that the demon army had in the first holy war has been lost. But because of the gods and the dragons, they didn't care about the mortal army at all, so they couldn't unite as one. The demon army took advantage of the opportunity. The three-realm coalition forces retreated steadily. The mortal armies finally abandoned the coalition and formed the continental United Army. In 1473, the Eastern Continental Allied Forces, led by King Piral Rafis of the Kingdom of Li, successfully defended the magic crystal mine near Lake Dent and joined forces with the hero Botan's North and South Continental Allied Forces to form a Continental Allied Forces to fight against the magic together. In 1477, Kuerte, the 8th generation Elf King, led the Elf troops to join the Continental Alliance Army. With the elves' enchantment magic, the Continental Alliance Army was even more powerful, and soon sounded the clarion call for counterattack.
