The Sacred Land is a continent ruled by the Dragon race. Beneath the Dragons, there are five major races: the dominant Humans, the sturdy Dwarves, the valiant Orcs, and the alchemy-savvy Goblins.

Millennia ago, led by Humans, the five major races overthrew the rule of the Dragons, ending the dark era initiated by the Dragons and ushering a new era of light. However, this battle created significant divisions among the five major races, which are once closely-knit—at least seemingly so. Goblins outright labeled Humans as faithless, yet when Humans questioned Goblins, they found no satisfactory answer. Meanwhile, the Orcs, who had promised to support the Dwarves, failed to appear on the designated battlefield, resulting in the downfall of the Dwarves, and a change in how the Orcs referred to the Dwarves—from valiant warriors to deserters. The once crucial relationships among the continent's most important warrior races were tarnished, leaving many questions unanswered. The wise Elven seemed to discern some hints of conspiracy, but they couldn't speak out because they didn't want to jeopardize the favorable outcome of the battle—well, perhaps it was favorable, but more importantly, they lacked any evidence. In the end, they chose to retreat, withdrawing to a place where nobody could find them, escaping the torture of their conscience.

Thousands of years later, an evil Dragon leads an undead army reappears on the Sacred Land, wreaking havoc wherever they go. Nobody knows when they emerged, but their name, "Undying Glory," sends shivers down the spine of all inhabitants. They raid and pillage seemingly everywhere at once, infiltrating and occupying the continent.

Faced with this dire situation, how will the five major races respond? Can they set aside their hatred and unite against the common enemy? What happened in the ancient war that caused the five races to turn against each other? Why did Humans overthrow the domination of Dragon? What conspiracy did the wise Elven heroes discover, forcing them to retreat in silence? Why did Goblins labeled Human race as faithless? How did the valiant Orcs become deserters? How did Undying Glory emerge? The answers to these mysteries lie within "The Power of Dragons"!
