The World we live in is called Gormod. Classes, Levels, and Rank Up's have existed since the creation of this world. 

Well, I'm not going to much into detail here's about how everything started. I will tell you however about my Classes Creation though.

Martial Artists like me always have been the most diverse in our skills because of our Specialization. So you would think we entirely overpower all the other fighter classes.

That, however, is inaccurate we have two very definitive weaknesses the first is since the style is different with each practitioner it takes a lot longer to master, the second is that after a while we stop advancing at all the experience we gain and training does nothing until we do a trial to get past this.

So in actuality, until we accomplish the first two other fighter classes have an advantage over us.   

The reason for this was the god who invented this class Metaru didn't want us to get over conceited with our power, so we had to prove ourselves to him. 

There is another unfortunate thing during the creation of this class an Evil God interfered with our trials to convert us into his servants. Transforming into a demonic race based on the species we were original.

When Metaru had found out about this God's interference, he was enraged who wouldn't be; it was however beyond his power to stop him though.

There was a war because of this between the pure and impure the scale of this war wasn't big like The Human demon war or the Vampire war, no one quite remembers about our fight at all.

It ended with numerous losses on each side both deciding not to continue "Officially" we ended up becoming of mortal enemies with each other, and we would try to stop them after they were about or did commit a serious crime.  

So we ended up getting divided into two factions because of this. If we passed, we would still be pure and level up again and if we failed we would become impure beings serving this evil god. 

Well, they were able to level up again also, So it was a very tempting offer.

The impure beings are joining the demon's in that army I hear. I guess it was inevitable that I would possibly have to face some of my former comrades in this war.

Now back to what the Trial or Trials consisted.

We are to understand our origins for some it's their species origin but for others who have a unique quirk like a particular skill or a mutation they have to figure out their species origin and the origin or reason they have that rarity.

We have to kill a creature that that has been harming the balance whether it be from the Light or Dark side.

We are proving Honor by completing a task that Metaru chooses with a method that we have to figure out ourselves.

The Scales Trial, We must balance ourselves in neither light or darkness but the harmony between both. They show us flashbacks where an overwhelmingly amount of light or a world full of darkness have had negative impacts on the world around us.

During these trials, Kendall, the evil god who made the impure faction will try to tempt us to due to the opposite like a demon whispering in our ears.

I had stopped gaining any experience after level 30. So it was time for me to undergo this trial. I had already overcome the first weakness of mastering my style though. 

For the first trial, I have to understand the Cave clans origins and probably why I have the essence detection ability.

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

 I had made it to Zomaria which is where the trials started; it took a month to get there where we go to an altar to take the first trial and receive instructions for the others their afterward. 

Thus the first trail started, the first flashback to the past where my clan first has begun, The scenery around me began to change, It took me to a period in history where various other races existed, there however a lot of species not yet created also. 

There was a problem however there it was plagued by a never-ending war, the balance of dark and light were entirely out of balance

 I saw demons destroying the other races torturing them killing them before their loved ones and other sorts of grotesque things.

The landscape painted red by the color of blood and organs, while the demons were laughing and mocking them in the process, the Dark side was utterly dominating the light side. 

The gods split upon on how to deal with this the light Deity's who were overall purists had decided to create Humans and give them unique adaptabilities like adapting to various climates, and they excelled at using the light element.

The god that created my clan, however, realized, that this would make the light side more dominant so he along with some other gods created species that could maintain the balance instead. 

He was right the humans not only destroyed the demons but all the other species that weren't humans. 

Their light element was almost blinding the entire area. There was nothing left like blood or guts; there erased their enemies instead of the grotesque murders the demons did.

It was like the humans completely denied there very essence with this.

So the god put his plan into action, he was the one who also designed the martial arts specialization. 

Metaru created the Cave clan with the personality of being passive and overall neutral but ferocious when needed for the balance. 

Some of the other gods whether evil or good had followed suite afterward not wanting the balance ruined.

This novel is published on a different platform. Support the original author by finding the official source.

The first of our tribe had acted as mediators between the two factions.

 They saw Villages and Cities burned to the ground, bodies, blood, and entrails scattered all over. It wasn't just Human corpses it was Beastkin another supernatural creature remains as well.

They also witnessed complete annihilation of creatures with nothing left remaining. 

The balance changed constantly going one way or another each era.

The prejudice was with all the races it seemed. They all viewed themselves as the superior species. 

Sometimes there would be a balance the scenery was now beautiful flowers growing everywhere there was still death. It was a lot less common though, and it was equal between the races.

 One idea would completely change this usually from who detested this peace.

These tragedies have caused us to be overly wary of many different races, so we ended up isolating our clan soon the other Beastkin races had followed suit choosing to remain in villages.

The flashback ended had finished. 

Afterward, I heard a voice, "It was entirely the human's fault see how their development has negatively impacted the world around us, killing of various animals and species to satisfy their greed for food and their twisted idea of "purity."

This Voice must be the evil God Kendall trying to tempt me the problem was he was not entirely wrong we hunt to survive, humans want more, and their idea of purity is completely messed up.

The demons want the destruction of all Beastkin and Humans, so they're just as bad though. I thought to myself.

The voice, however, read my thoughts and asked."Are they though? How many supernatural species are there compared to humans? Most demons want Beastkin also gone because they lean more toward the human's side right?." 

"What about the complete chaos there was before humans came into being then?," I Inquired, the voice then went silent.

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

The next flashback was starting I was back in my village the scenery was the same. 

A bear Beastkin was talking to the chief. He was to go on a mission to take down an impure. 

He was about my height and had the same face as me.

There was another village of bear Beastkin sending someone as well they looked like us but had white ears and hair. 

It was a girl who also had some of my traits like the shape of her nose and ears.

This clan excelled in the Assassination class. These two knew each other and were secretly lovers. 

They were going to tell their chiefs about their love after killing this impure.

This impure was almost on the verge of ranking up, so they needed to eliminate the threat before it happened they didn't know the name of this polluted one.

They got a description of this impure he looked just like a bear but a bit more humanoid.

He left a trail of corpses wherever he went he was headed to the location of some other impure.

They went on to intercept him. They caught up to him in an of couple days it was on a faraway mountain almost at the summit.

He was eating what looked to be like a child from a human village who looked no more than eight years old. The impure were known for eating humans.

They usually wanted one with more meat on them though. The small town the couple had passed by earlier was empty it was on the small side.

It was probably the tainted one that did this the couple had thought. The kid was still safe he could have his limbs regenerated, so they opted to stop the beast before he finished.

The guy distracted the creature with his skills while the girl sneaked behind and tried to sneak up behind him and attack his vitals.

This attack, however, didn't work because the impure one had already Ranked up. 

So it would take more than just the girl's daggers to puncture his skin. They had to work in perfect harmony to defeat it.

This strategy was a difficult one as they also were trying to save the human child as well.

Fortunately, they were both proficient in the sense skill so they could aim when the impure one had an opening.

They pretended to escape they were both proficient at hiding as well. 

So the tainted one believed they were gone as they were both fast and with it not even noticing it they grabbed the kid in the process.

They gave the kid a potion to regenerate his limbs and organs, that potion provided by the male's chief he gave it to him before leaving the village just in case of an emergency where they were one of them severely injured.

They knew that this was a risk for them, they both didn't want the kid to die though.

They then told the kid the location to male's village to where they shared the information of the male's community to the kid as well as the direction along with areas of where to get food along the way.

The kid ran away once they were for sure the beast was out of sight of course. They waited until he was far enough way to attack the impure one.

The girl said "If we survive this mission I have something to tell you," the guy could guess to what she was going to say.

This creature had to die,so they would have to risk this for the sake of the balance no matter what the consequence.

They both sneaked up to the beast to attack the creature however was amused, he had gotten more used to his new species from his current rank up, and the fact that he was impure meant he had some not so true desires.

 He could now tell they were coming; he pretended to let the kid go as the boy was as he was now fund of this amusement and desired to tear them apart and before they died to tell them that it could catch up to the kid at any time and kill him he would follow through this of course.

The couple was stopped midway between the attack and knocked back aways during this the tainted one took some of their fingers off to show them as they were landing to the ground.

The couple knew there was more to him even after finding out about his rank up they had a final ace up their sleeve they probably wouldn't be alive afterward it was a suicide move.

It was a combo move they yet to perfect that combined both of their specialties they hadn't fixed the bugs in this again. So the backlash was immense.

They combined their Elemental aura's of water and electricity into their attack and lunged at the opponent. The tainted thought he would survive it by blocking it.

His element was fire though so even if he channeled it during the block, it would still kill him which it did. 

The male died instantly the female somehow survived, she was however to injured to move.

She was devastated why did only she survive? The male, however, had a smile on his face she realized he took on the brunt of it by himself.

He was a hypocrite; she knew he had thought they both had to risk themselves as well as him knowing she was pregnant. 

He couldn't follow through with it and desired to protect her and the child with that unimaginable will of his he chose to take it on himself.

 Half of the day had passed by, and the kid who they had rescued returned. 

Why did he return? She thought, she couldn't talk though he voicebox was damaged and the boy somehow with his weak body dragged her all the way back to the male's village.

The chief didn't have any more potions left they were scarce and would take a year to find or produce a new one.

He knew that she would eventually die anyway he, however, thought it would only be a couple of days.

 She was somehow, however, to survive for nine months passing away slightly after her child was born.

The flashback had then had ended.

His parents had died a very tragic death, and he was never able to meet these people with a beautiful love between each other as well as willpowers that only he had heard about in the legends of old. 

Clyde was shocked as he realized the reason he could sense essences was that his parents had been superbly efficient with the "sense" skill, that stemmed from entirely different classes. 

"Yeah, but they still left you didn't they were never around you because they died, by sacrificing the kid. However, they could have escaped right?" The voice interjected.

"They would have been shunned by their entire clans then though for failing to save the kid or killing the impure," I stated.

"They could have started new lives elsewhere wasn't that important enough for a child." He declared.

 I ignored him I knew he wasn't right although it was getting harder to listen to him,  A new Voice then said, "You have passed the first trial as for the next trials you shall have to"...
