Limitless The Strongest Revenant

"Yes, they just get a blanket FRM. I would know as I am Formless."

"Mmm, there isn't anyone in Hellsgate who doesn't know that fact. Specters even more so. Anyway I am sure that while it helps, knowing just the Reaper Id of a Reaper would not let you know how he or she particularly fights. There is a separate system for that." Your journey continues on My Virtual Library Empire

Carlos then pulled out a piece of paper and began writing on it. I originally was worried that I wouldn't understand if he wrote in anything but English. Luckily, my teacher was quite considerate.

"Right, first off is the Class. Every single Reaper falls into seven class. These classes serve as archetype that describe the combat doctrine of a Reaper's {Fate}. Academics has theorized that the seven continents are the reason why there are only seven classes. And each class has a continent where it comes from."

Classes? Like knights, wizards and mages? Reapers had such things? Funnily enough, I could immediately accept his words as I have been trained by IRIS and video games.

'Fuck. It is scary how effective IRIS has managed to create materials to train humans in Reaper concepts.'

Oblivious to my tangents Carlos continued.

"The Seven reaper classes are Keepers, Rulers, Chasers, Linker, Summoners, Shifters and Enhancers."

Well fuck. Aside from Summoners, I didn't understand shit.

"Despite the unique terms you would already know what they are."

Carlos mapped a continent to the appropriate Class.

"To map it to a continent's combat style it would be as follows. Keepers come from the North. Australia is the origin of Chasers. Linkers are mostly European. Summoners come from South America. While Africa births most Shifters.

Asia is made up of Enhancers. Finally, your continent is the only one who fields Rulers. Do you follow?"

Having him connect it to something I already understood made it easier to remember.

"Alright then I will begin to explain them now. One by one. As for easily understandable examples I will use the Revenants as they are the best demonstrations of the highest forms of the classes. I will also add the Domains to the classes for further understanding."

"Yes, please," I replied eagerly.

"Okay first let us start with Keepers. Basically their power comes from a Soul Oath. In envisioning the {fate} or the reapers regret to create a Soul Oath as a result. A Soul Oath has two parts the sacrifice and the payment.

"These would be the people who say stuff like, 'If I could have this I'm fine being that'. Oath Keepers are all about sacrifice. In order to gain anything they increase the strength of their Oaths.

"The North's Erik Odinson is the ultimate example of this. His {Fate} is called {Oversee} it defines a place to call his kingdom. As a Keeper his Oaths all revolve around his kingdom. The most famous of his Soul Oaths is that he cannot leave his kingdom. And as a payment he is the equivalent of god in the area he oversees."

"A god? That has to be an exaggeration. I can get humans saying that but not Specters."

"No, I am not joking. The day the North fell, a large force comprised of a dozen Archdemons led by Paimon the 3rd came to Earth. Erik Odinson single handedly annihilated them all at the cost of destroying most of his kingdom."

Chills went up my spine. The two Archdemons I already fought, Andromalius and Bifrons were stupidly powerful, but they were only ranked 72nd and 68th. Just how powerful would the 3rd ranked demon be. And the bastard had 11 others with him.

"Wait, wasn't the 3rd ranked Astaroth not Paimon?"

"BLURT!" Herman suddenly spit out his coffee. "HOW THE FUCK DO YOU KNOW THAT?"

My teacher rubbed his chin as he commented in interest. "Herman, calm down. Interesting. Yes, you are correct. When the one who assaulted the North were destroyed many tried to take their place. The one you spoke of indeed gained the 3rd rank after a bloody internal war."

Herman then grabbed me as he franticly shouted, "Listen you fucker, do not say that name haphazardly! That Archdemon in particular has something like omniscience! Be careful! Call her something else!"

I glared at the conquistador and then his hand on my arm, "Let go of me, before I make you."

"Herman…"

"Alright. Already I was just trying to help. How did you even know her?"

"The Vampire thing in the 30th floors was her doing. She instigated Bifrons the 68th. I already killed him but not before he bitched that everything was her fault."

"…" x2

"What?"

"Ehem… Anyway. Where was I? Oh right. Erick Odinson The Unbreakable got his alias for repelling the invasion alone. Many believe it was because of his Oaths as a Keeper. But as hardly anyone from that era remains alive we will never know."

"Then how do we even know that it is true?" I challenged.

"The information has been verified by multiple Revenants. IRIS the source of the information shared it to the younger Revenants. It is safe to say that he is at least not from our period unlike the rest of the Revenants."

If that was the case then does that mean that the current North is a survivor of the previous civilizations? I should ask Liv when I get the chance.

"Returning back to the topic at hand. Keepers in general are powerful in exchange for binding rules among themselves they grow in strength. But there in lies the way to defeat them.

"To Keepers in particular, breaking ones Oath punishes them with massive amounts of malice. It is to the point that no Keeper who broke an Oath remained sane afterwards."

I see. That was indeed fair. To Keeper class Reapers, the Oaths were a double edged sword. Among the Sirens Liv was definitely a Keeper, I should learn what her Oaths were so I could help her in keeping them.

"Now, here is a fairly interesting question for you Limitless. As a Keeper's strength is based on his Oaths what do you think happens when he gains a Domain?"

Unable to understand what he was asking I stayed silent.

"As I mentioned, Domains are the natural extension of a Reaper's {fate} to influence the world around him. From this definition Keeper Domains normally fall into two schools of thought. Domains that strengthen an Oath and those that removes it."

At his words I felt my body shudder. What would happen if Erik Odinson a god in his kingdom suddenly losses the restriction of staying in it? Or what would happen if despite his power his domain increasing his power even further? How would anyone kill him!

'Wait. As the bastard is already a Revenant, he should not be able to grow stronger. Then that would me the reason he gained that much power was because probably because he strengthened his Oath.'

"I see. So he allowed the rest of his kingdom to be destroyed in exchanged for being able to protect his chosen kingdom."

"Excellent. You are correct. We came to the same conclusion. But it just goes to show the power of Keepers. Now for bad examples, are you familiar of Cú Chulainn?"

I was about to answer when Exa sent me the info.

[Cú Chulainn a famous demigod hero of Ireland. His father was the Irish god of justice Lugh from the same mythology. He carried the demonic spear Gae Bulg. If we follow Carlos' line of though, it would implies Cú Chulainn was a Keeper Class Reaper.]

'What? That has to be some kind of bullshit I could understand that he appeared in anime and manga but to exist as a Reaper?'

[But my lord. The case of Isolde Drache already establishes that legends are based on Reaper history. Interestingly enough, part of Cú Chulainn's legend involves supernatural vows called geass. Which are fundamentally what Soul Oaths are.]

'How did he die?'

[He died after being stabbed through the heart. He tied himself to a standing stone to die on his feet. The work that records his death "Aided Con Culainn" has specific section on how the sons of the famous warriors he killed made him break his geass one by one.]

'You can't be fucking serious.'

[Cú Chulainn had seven geass. All of which he ended up breaking. From eating dog meat, accepting hospitality, being calm in battle, having friends and lovers, to not losing to any man in battle. He only died after all of them were broken.]

"Fuck…"
