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.

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!

In the year 2093, mysterious energy known as mana descended upon Earth for the very first time in millions of years. People began to spontaneously awaken, allowing them to gain supernatural abilities, classifications, and affinities.

Simultaneously, dungeons with immaculate treasures and horrid monsters began to appear all over the world, forcing humanity to stand together in order to survive.

Lloyd Elrod was a simple boy at first. He was a boy with no power and little to no social standing, yet that all changed on the day before his awakening ceremony. The day he became what the humans and the other races saw as a monster.

[Welcome to the Void]

It was the day he became a Void Walker. A race capable of growing faster than any other. A race with individuals capable of putting an entire civilization created by a multitude of races on the brink of collapse and walking into the Void itself.

Having become a part of the most wanted race in the universe, Lloyd is forced to hide and fight to keep his freedom. In order to not be restrained by those he once saw as his brethren, he must become strongest.

Will Lloyd be found out? Will he finally earn his freedom and have control of his own fate? Join Lloyd in his journey of joy, sorrow, grief, and pain as he climbs to the top and becomes the most powerful creature in existence.
