“Success is a shallow foundation built on luck and circumstance. Failure, accumulated and stacked like endless bodies in a mass grave, forges the deepest roots into unshakable power. I know all this about power with surety as all I had were countless failures. After all, I am Vakochev, and I set the very Scales of Existence. This... is my story. Existence, is my Story.”---In the brutal Lands of Stone, where mountains move and beasts devour civilizations whole, power is the only currency that matters.Damian Vakochev was once a prince to a glorious power, but he was stripped of that power, family, and everything he held dear as he was left with a shattered foundation.In an age where tribes war for scraps and Neolithic Empires crush all who oppose them, where ancient beasts roam territories older than memory and Mana flows through the Lands of Stone like blood through veins, where Warriors reinforced by Mana who could go against entire armies and Primal Beasts could devour entire mountains, Damian looks upon it all and asks...why?Who said things had to be the way they were? Who decided what power truly was?Why could he not stand over the tallest mountain and declare exactly what power was as he saw fit?!Why did he have to follow the set path of cultivation? Why were others born with Land and Sky Physiques while he was not? What prevented him setting up his own rules and his own paths?!

In a time when the Divine Prefectures of the East Sea were in great disarray, Emperor Ye Qing and Donghuang the Great appeared to save the day. Under their rule, the prefectures united and all nations as well as their kings have been controlled. However, the legend of these two great heroes becomes altered when Emperor Ye Qing’s name is wiped from the history books after his sudden death. All statues and images of him were destroyed and his name a taboo. Only the legend of Donghuang the Great shall live on.

Fifteen years later, a young man by the name of Ye Futian begins his journey in search for his true identity. The legend of Futian was going to be one for the history books.
