Long ago, a dungeon appeared in the world.

It was on a scouting mission and had successfully found a viable world full of people and resources.

Soon afterwards, dungeon after dungeon invaded the world. They took over the planet and unleashed their monstrous creatures and wreaked havoc upon the lands.

The infestations of the dungeons ended the peaceful world and brought upon the Age of Apocalypse. The world as it was was destroyed and laid in ruins.

However, all was not lost.

The appearance of a tower was a beacon of light, giving the people of the planet a way to fight back. One by one the towers appeared across the planet.

They gave select people the power of summoning, and for a price, the survivors of the apocalypse contracted and summoned forth powerful beings to take back their world. The native inhabitants fought back against the invaders pushing them back and taking back pieces of their lost world.

The battles turned to war. A war of attrition that to this day had no end. Through time areas around the towers became kingdoms, strongholds for the last of humanity. And the dungeons were forbidden areas not to be ventured.

Generations passed since the times of the first summoners. However, the war never ended. A seemingly normal boy would soon find out the troubles of his line. With no choice he had to take the only summon willing to contract with him.

A system.
