Destiny Without Desire

An unknown species existed in a land that the humans never dared to enter. What happens when the presumed extinct species encounter the humans?
Will the lords of fire, earth, air, and water be able to gift death to this evil species? Will the ruby, forged in the Egor mountains, be separated from the king of giants? Will it be destroyed to end the evil on this planet? Will it be possible for the young lords, who are still at school, learning their lessons?
When the moment arrives, the giant's king, Maut, must be made to perish at the same instant the ruby is destroyed. Who has a plan? Who will strike to finish?
