Mana system:

A system that utilizes all aspects of Mana and its properties. The system can create and manipulate the matter that is produced by mana, to its will.

Mana is an energy source that powers the world and is accessible to everything and everyone. All things have energy, hence everything has mana. And if the mana is harnessed, it can be manipulated into elements or other supernatural objects.

The mana system uses the mana in your body, since mana is energy, you will feel a decline in emotion and you will eventually lose control of your body, but in some rare cases, death.

Berserker system:

A system that utilizes the physical and acrobatics of the user. This system can cause the user to grow in size, or their strength will grow regardless of Mana.

But getting too strong will damage the users body, and in some rare cases, break their nervous system and disable them.

Warriors system:

A system that uses the loyalty of one's user to their leader. If one's loyalty is high, the warriors system will enhance them by sixfold and raise morale.

Soldiers mainly use this system in war and protecting civilians. They are able to cast spells upon civilians to move them for crowd control and clearing an area where a disaster may appear.

The knights of Henrietta are the mightiest warriors, they have dedicated their lives to Henrietta and fight for her regardless of the absurd tasks that are put on them.

Ranger system:

The ranger system relies on accuracy and the precision of one's ability to shoot a target. This system relaxes the user for them to have full control of their weapon, and gives them enhanced vision to create a more clear environment for them to aim. It enhances their endurance for the fatigue that they feel after holding up their bows for long periods of time.

Assassin's system:

A system that utilizes the acrobatical ability of the user, the swiftness of their body, and their stealthiness. This system mainly focuses on dexterity and stamina. So to move at high speeds for longer periods of time, one would need more stamina.

This system also relies on the physical build of the user. Ones legs must be properly built, for the fast and sudden movements that these users make.

The system can hide their scent, and their presence will be undetectable by others who are of lower rank than the user.

Demon system:

A system with demonic powers, derived from the Demon King, Lenard "Lucifer" Helm. The name Hell is derived from his surname. In a frustrated anger, he created a system that allowed the user to utilize the abilities of a true demon.

All of these Systems can be broken down into smaller groups.

The only known berserkers are the Tigers, Brutes, Bear, Polar, Croc, and Gorilla systems.

The mana system has lots of users. Mana is accessible to everything and everyone, but the mana system is different. The mana system allows the user to manipulate and morph their mana in any way shape or form.

Healing spells, fire, lightning, water, anything that the mind can think of. Mana is by far the most common System. But it is only accessible when you have trained your mana for years, sometimes even decades.

A warrior's System is also very common. It is mostly used for knights and soldiers for a kingdom, but mana users can also utilize it.

With the combination of necromancy, one can turn a simple skeleton into a force that would be unstoppable by a regular human.

Warrior systems work well in groups and are some of the most loyal people.

The rangers System allows for more accurate shots with ranged weapons. Some may use this system for hunting, or a kingdom can have an entire force of them for battle.

The assassin's system hides the presence of the user. It is great for bounty hunters and spies. Some berserkers may combine their system with this, for a more acrobatic system.

The demonic system is one that is almost impossible to obtain. It can either be given by a demon, or one can get infected and killed, then revived with the system.

Demonic system users have a strong bloodlust and rage. Some just have strong lust, like a succubus or incubus. But hese users kill without hesitation, they have no regard for human life, and some go insane to the point of suicide.

The land of Vendrige is covered with lush vegetation, its odd shape and high elevation is a breeding ground for bugs and small critters.

North of Vendrige is Hell, a large hole in the middle of the world that leads into the Demon King's Palace. Covered in death and decaying plants, it's a shitty place for adventurers.

North of Hell is where the Trade Capital is, Cambridge. An industrial wonderland with all sorts of machines and automobiles.

East of Hell is Arikaf, a desert that is laced with venomous creatures and prickly cacti.

West of Hell is Dremel, the country of Elves and a harmonic, peaceful country. This is where the Great Tree of Mana was grown. But after its death, mana was blasted into the skies, and now it glistens with life.

There are 5 major cities in the world. In Arikaf is Neadle, a city full of gold and ancient scripts. In Dremel there is Gillmus, the city of Elves, and peace. There is rarely any discrimination in the country of Dremel. Cambridge is both the capital city of trade, and the sole reason why people have colonized the other parts of the world. Vandrige's capital is Velm, a land with rich soil and the main source of agriculture. In Hell, the Demon King's Palace is a large castle-like building that wraps around the hole in the earth.

This is a joke novel, there are multiple references and slang used in this. It is all a joke, this book is not meant to be taken seriously.
