This is an auxiliary chapter that I am going to dump some information that you didn't notice or forget because of the passage of time. Though there is some information that you don't read at all, such as names of the other kingdoms and a basic continent map that I drew. 

-------------------------

PATH TO POWER FOR HUMAN

Candidate: Candidates are people with symbols on their foreheads. They have no actual powers until they awaken their potential and vanish the symbols that are on their forehead. 

Awakened: Awakened are who awakened their potential in one way or another and gained mystical/magical abilities. 

Master: Masters are people who have mediated about their powers, increased the amount of their power, and gained understanding of their unseen capabilities. Masters are people who are more or less proficient with their powers and usually know how to use them in different situations. 

Grandmaster: Grandmasters are people who mastered their abilities completely. They know everything about their abilities and gained one more mystical ability that births from their 1st ability. 

Transcendent: Transcendent people are who transcend the human and become something more. Their abilities are crudely mixed with their bodies, making them something different than humans. They can now mix their abilities and can transform into mystical creatures, though this form too is crude and lasts only a few minutes.

There are a few more levels of powers but, well, read and see them as they will appear in the late chapters. 

------------------- 

Changeling: The weakest and least powerful of the monsters. They often takes on the form of an deranged animal or human.

Devolved: The second stage, where the Changeling has begun to tap into its monstrous nature and develop some abilities and strengths.

Monstrosity: The third stage, where the Devolved has devolved more into a dangerous and cunning creature, with specialized abilities such as poison or curse. 

Aberration: The fourth stage, where the Monstrosity has become an anomaly, possessing strange and unnatural abilities or mutations that make it difficult to fight.

Horror: The fifth stage, where the Aberration has achieved a level of power that can induce insanity or madness in those who witness its true form or abilities. 

There are a few more levels for fiends as well, I will introduce them too later in the novel. 

----------------- 

CLASSIFICATIONS FOR FIENDS 

Basic: Most common fiend class. They are just basic fiends with normal bodies and abilities. 

Parasitic: A rare fiend class that lives and possesses a body. 

Shapeshifter: Fiend class that can transform into something different than their main looks. It can be basic or completely different, this changes according to the strength of the fiend. 

Mindbender: They are usually more intelligent than the fiends of the same rank because of their speciality, which is mind. They aren't strong physically but there is no need for it either as they can make people kill themselves with a smile on their face. 

Dream: Fiends who live on dreams of other beings. They are the 2nd most unique and most hard to kill fiend class. 

Spectral: Spectral fiends are fiends who are intangible, impossible to kill or touch with physical means. Such as ghosts, spirits, shadows. They usually damage the soul instead of the body.

Apex: Apex fiends are fiends who can control or create other fiends of their kind. 

Hybrid: These fiends are the most unique ones as they have a minimum of 2 different class traits. They can be Apex and Spectral, or many more. They are dangerous and if possible kill on sight before becoming big trouble for the future.

MAP 

Map of the continent (Look at the paragraph comment)

Sevuri (Coming soon...)

Dalinnor (Coming soon...)

Macien (Coming soon...)

Neladrik (Coming soon...)

---------------- 

Churches

Titles for the members of the churches:

Deacon -> Priest -> Head Priest -> Bishop -> Archbishop -> Cardinal -> Pope

Trainee -> Crusader -> Heretic Hunter -> Inquisitor -> High Inquisitor -> Saint Inquisitor

Trainee -> Holy Knight -> Paladin -> Archpaladin -> High Champion -> Saint Champion

Unless someone does significant things, they usually given title according to their power levels, for example; Paladins usually are Masters while Bishops are Grandmasters.

As for what comes after them, you will see in the story later ;)

Anyway, there are 4 main churches and a few small ones.

Afterlife Church: Stationed in the Macien Kingdom, believes in the [God of Afterlife]. Most of them don't care the lives of other people other than man/woman of faith. They practise celibacy as they hate [Church of Life]. They are a bit dark-oriented in ability vise and they love this. Life is meaningless for most of them.

Church of Life: Stationed in Dalinnor kingdom, believes in the [Goddes of Life]. They are mostly gentle beings who likes to take care of the lives without discriminating if it's plant or animal, though they are merciless against to the sadistic sinners.

Church of War and Peace: Stationed in Neladrik, believes in [Goddes of War and Peace]. They are strange beings that both loves the war and peace while thinking the wars as a necessity for humans to survive. They are natural warriors and diplomats.

Church of Mortal Divinity: Stationed in Sevuri, believes in [Mortal God of Sevuri]. They are a bit supremacist with great belief that every human can attain divinity like their God. Unfortunately for them though, they are the weakest of the 4 big church.

---------------

GATES 

Gates are mostly random portal that opens a gate to an unknown dimension. Most people don't know the reason for the gate openings and why mindless fiends or intelligent creatures come to their world and kill, and destroy whatever they see. Most of the denizen of this world just does whatever they can to hold these monsters and predict the dangerous gate openings.

I will update this auxiliary chapter whenever the story comes into something different or complicated, or I am bored.
