Prologue

Over 400 years ago, in 1914, the first dungeon appeared in a state in America. Not much is known about how and why dungeons appear, but we do know is this what's inside dungeons: monsters. Goblins, trolls, wolves, centaurs, fairies and pixies. You name it, there's a dungeon out there that has it! A dungeon contains many floors, and the lower you go, the more dangerous the monsters. Dungeons are grouped together using numbers, and are then followed with the letters of the alphabet, from A-Z.

An average dungeon will have around 100 floors. At the 40th floor of a dungeon, there will be what is known as the safe zone, where the people who have ventured into the dungeon can rest. Once the core of the dungeon on the 100th floor is destroyed, all monsters still currently in the dungeon and monsters who have escaped the dungeon will be enveloped in a black smoke and disappear. The people who are still in the dungeon are also enveloped in a black smoke, and sent back to the surface, with the dungeon doors disappear, never to be seen again. What the black smoke is and where it takes the monsters to after the core is destroyed is still unknown. Around a month after the core is destroyed, a new dungeon will appear.

At the 75th floor, there will always be a treasure room, where gold and artefacts with different magics enchanted on them can be used, and when the core of the dungeon is destroyed, the gold and artefacts in the dungeon will also appear on the surface along with the people in the dungeon.

Thanks to the appearance of dungeons, 2 new jobs were created by the International Heroes Association, or IHO for short. The 2 jobs that were created, Adventurers, created so that dungeons and the monsters that resided in them could be defeated. Heroes, created so that Villains, a term given to those who abuse the powers obtained in the dungeons, could be defeated and arrested

However, Heroes and Adventurers must have "Abilities", a magic power that can only be obtained by random at birth, except for rare circumstances.

When a monster is eliminated, it sends out a small pulse that can't be detected by modern devices, however, new born can detect this pulse, and the nearest new born to where the monsters has dies may end up with the chance to receive the abilities of the eliminated monster.

This type of receiving an ability is called "Pulse Transitioning", and usually, only 1 or 2 abilities are received by the new born.

New born can also inherit abilities from their mother and father, and their powers will become very apparent from the age of 6 months to 5 years old. Inherited abilities can morph, combining the mother's and father's abilities to create a totally new ability.

This type of receiving an ability is called "Inherited Combination", as the parents abilities are seen as equal and combine to make an ability never seen before.

The last type of receiving an ability is called "Dominant Inheritance", where the magic power from one parents abilities outweigh the other parent, making the parent with the more dominant ability to be inherited. As well as these types of inheriting powers, unlike when a new born obtains abilities through the small pulse, 3-4 abilities can be obtained if a child is inheriting their parents power, and new versions of the parents powers can also be created during the process.

The magic received through these three ways are called 'Impure Magic'. Impure Magic is magic that originates from monsters and is not yet in its complete form. 'Pure Magic' is magic that does not originate from monsters. This type of magic is overwhelmingly more powerful than Impure Magic, since this magic is thought to originate from the source of all magic, the original dungeons core, called by many as The Lexwell Dungeon, or Point ZERO.

The magic from Point ZERO have also caused the genetics of humans to change, which because of that, made unnatural hair colours become a normal part of the world, half human half animal hybrids became a common sight to see, and people with unnaturally coloured skin blended into society.

Adventurers and Heroes must all have magic abilities to gain their title.

Adventurers: These are the scouting teams who enter the dungeons and make it as far as they can to confirm which floors have what monsters. Adventurers usually form Guilds with other adventurers, and these Guilds will enter dungeons as a team. Almost all Adventurer Guilds have a team of Heroes who will accompany them through the dungeons, as Heroes are said to be the ones who have people with exceptionally powerful abilities.

Adventurer Guilds are ranked using a system known as the 'Level Leaderboard' which ranks Guilds on how many floors, or levels of a dungeon they have descended and cores they've destroyed in the past 6 months. The chart is updated every 6 months. Rewards are given to the top ranking, usually the Top 5 guilds!

Heroes: These are the teams who will eventually enter the dungeon after the adventurer's scouting missions, so that they can destroy the core of the dungeon. Heroes are believed to be for those with more powerful abilities. Heroes mostly have to deal with Villains, which is why is is believed only the strong are accepted as Heroes. Monsters who have escaped from Dungeons will also be targeted by Heroes.

For Heroes, there is a ranking system, known as the 'Power Chart' which ranks a hero based on how many villains defeated, people saved, and dungeon cores destroyed (which are worth 10 points in the total add up) in the last 6 months. The chart is updated every 6 months so that those who follow different heroes can see how they're doing. Rewards are given to the Top 10 in the charts!

There is also an event that happens every 5 years, known as the "IHO Magic Awarding Ceremony", or the "MAC" for short, where Heroes and Adventurers are given awards for their courage and putting their lives on the line to destroy dungeons, monsters and defeat villains. During these ceremonies, your class will be updated.

Classes are a measurement of a persons magic power. The classes are as follows:

10. Beginner

9. Intermediate

8. Advanced

7. Apprentice Divine Mage

6. Divine Hero

5. Apprentice Master Mage

4. Master Hero

3. Apprentice Grandmaster Mage

2. Grandmaster Hero

1. Superhero

Once a person reaches the Superhero class, they are tested to identify those who are strong enough to reach the next rank, which gives a general idea of the stronger Heroes and Adventurers.

There are currently 6 ranks that are globally used. They are as follows.

6. Epsilon

5. Delta

4. Gamma

3. Beta

2. Alpha

1. Omega

These 6 ranks are used worldwide to determine the strength of the best Heroes and Adventurers.

As for the story you are about to read, it is of a boy who encounters a monster that will change the course of his life forever, for better or for worse!
