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?

Now, knights want to slay him, cultists want to worship him, and political schemers want to manipulate him, all while he desperately tries to convince everyone that he is just some guy.With misunderstandings piling up faster than he can escape them, Darin must navigate a world that insists on making him its next great villain… whether he likes it or not.A comedy of mistaken identity, accidental power plays, and one very confused protagonist, I Was Mistaken for the Reincarnated Evil Overlord is a lighthearted fantasy adventure where every denial only makes things worse.

It is the year 2050, One of the world’s greatest assassins had fallen. Will his successor continue his legacy?
