Ecto, the third son of the Margrave of Glenreed, received the skill of Earth Magic during his coming-of-age ceremony. However, Earth Magic—unsuited for combat—is considered a so-called "dud attribute." As a result, he was disowned and appointed as the lord of the remote and desolate Border Village. But thanks to a certain secret, Ecto had come up with ingenious ways to use Earth Magic that ordinary people would never imagine! Together with his companions—including the female adventurer party Wings of Attack, who serve as his guards—he defeats magical beasts, clears forests, cultivates farmland... Thanks to Earth Magic, Border Village begins to undergo a remarkable transformation! (Source: Alpha Manga)
