A Betrayal of Fate--- Anos Voldigoad, a young man of noble spirit, faces a devastating turn of events. Betrayed by his own kind and the woman he loves, he’s thrust into a world of darkness and despair. His world shattered, his parents murdered, and his beloved forced into the arms of his sworn enemy, Anos questions the cruel hand of fate. As he succumbs to his mortal wounds, a final, haunting image lingers: the smug grin of his tormentor, taunting him with promises of his lover’s destruction. In his dying breath, Anos wonders: Why has God forsaken him? Is it because of his weakness, his goodness? As the darkness claims him, a seed of vengeance is planted, a promise to rise from the ashes and exact his revenge, no matter the cost.

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?
