Two brothers, Alexander and Seb, are well-educated but hunger for adventure. Intrigued by some ancient maps and stories of old, the boys slip off on what begins as an innocent excursion from their home along the shores of a vast lake, Sempersee, to a nearby island. After finding a mysterious stone, their outing leads to a quest to discover the rightful owner of the Flame Stone, an ancient artifact that holds the power of goodness. With the wise guidance of their guardian, known only as the Old Man, the boys must rally their young countrymen and prepare for battle in order to protect their humble land while on a quest for the true owner of the stone.

Can the boys find the rightful owner of the stone before evil overshadows their country? Will humble, young farmers be prepared to battle experienced armies with only weeks to prepare? Can the boys carry the burden of the Flame Stone and right the wrongs of the world?

The fate of the world is in the hands of Alexander and Seb as they enter into an adventure that will change the course of history.
