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.
