In the wild plains of Europe one side of the field was an army of werewolves on the other was an army pf vampires it was pouring down rain even though it was sunny out they were waiting on their commanders to give the order to fight each other on the werewolf side they were having a meeting on how to best end this conflict as how to end the war with every other race as well.
Their answer came when they saw the royal carriage on it's way to the battlefield showing the sigil of the princess Katherine once her carriage pulled up she got out she had chestnut hair olive eyes dark complexion medium height slender frame nicely built double C breasts taught but supple legs she was dressed in armor expecting to fight she had a helmet on a shield with a wolf on it a sword and carried a spear on her back that was cut in half as well as a bow and arrow.
When she stepped into the tent she was surprised at how unprepared they were for combat they only carried one weapon on them also they wore light armor almost like they weren't expecting this war to last much longer which shocked her when she took her helmet off she was disappointed in their attitude when they looked at her almost like she was they answer to their prayers.
Katherine asks" why aren't you leading your men into battle like they expect you too "
One of the werewolf generals smile at her then says " my dear princess it's thanks to you that we've figured out how to stop the wars with the other races as long as they agree to it "
She looks at them like they've lost their minds then asks" how does seeing my fave inspire us to stop fighting against the other races"
none of them speak up but the only woman in the group of generals smirks at the princess then says" its rather simple princess as i'm the one who came up with the idea after seeing your face when you got here we're going to have our females or our males seduce the other races that we're fighting against"
The princess couldn't argue with the she wolf's plan it was a good one but a risky one she thought about it and essentially to pull this off they would need every person standing here today including herself she tells them as much and they can't argue with her math so they order the army to retreat only pack what they can carry and move out.
The army complained but they did as ordered once they got to where they needed to go they spent several years putting the army through the academy reason why they're doing this now is because these soldiers never got a chance to be educated like with everything else they complain but they do it until they graduate the subjects are:
math
language arts
science
social studies
foreign language
blacksmith
carpenter
architect
doctor
soldier
assassin
seduction
survival
infiltration
espionage
assassination
boot camp
After 400 years they have completed everything and chose a job that would best suit them half stayed away from the combat jobs but the other half chose between being an assassin or a soldier they simply chose what best suited them a handful combined both into one making them extra deadly but one day after everyone enjoys being a graduate before they can party too much.
They all get called to the big hall and re go over seduction then they say "that the end of the war is at hand all you have to do is if you're male seduce a woman to end the war and if you want marry her if you're female seduce the man to end the war then if you also want to marry him the marriage is optional for you guys just in case everyone is thinking that only the soldiers are doing this mission then you're wrong everyone in this room will do this mission."
That made everyone else happy but also worried when they saw the princess walk onto the stage then it hit them that she was doing this too but some random soldier who likes to be a nuisance asked "if we're doing this mission what's the princess going to be doing " the leader of them sighed and says " she will be doing the same mission as everyone else it's just that her person won't be the same as everyone else's in fact everyone is going to have a different person and as hard as it is to admit we actually need someone to volunteer to seduce the princess's brother and sister so we can end this war a lot sooner."
Hearing that shocked them but nobody volunteered for such a hard assignment except 2 people a female general that ever man has been trying to get with but she ignores them and a male general who is charismatic who every woman but the princess has been swooning over since they saw him Katherine hands them an envelope with information on her siblings it has their likes dislikes dreams hobbies past relationships political aspirations what projects they're currently trying to get up and running.
Katherine is handed tons of envelopes she passes them out to everyone they pass them around until they get one with their name on it they open it it has their target's :
Name
Sex
Race
Region
Age
Rank
Powers
Likes
Dislikes
Dreams
Hobbies
Politics
Debts
Crimes
Personality
Everyone was surprised by how detailed it was but also how vile some of these men and women were it almost made them want to go back to fighting it wasn't that they were bad looking a few of them were but most of them were attractive it was their crimes and personalities that was the turn offs alas they knew that if they didn't do this the war would never end and their species would go extinct so they go with this plan.
The plan goes off without a hitch in fact every seduction mission other than Katherine's was successful and everyone has married their target because they're tired of war also they want a family they don't even try to hide their relationships they flaunt them to the world not bothered by the fact that everyone knows that they're mixing races.
The vampires at first thought it was a move to annihilate them until they only kept 3 weapons with them each a sword a spear a bow and arrow and a shield as well as some light armor just in case but the rest of their equipment was sent back to the wolf nation and their spouse did the same with their equipment after that seeing that they knew they weren't amassing an army just getting with a partner from a different race.
Despite their purist views they knew that other members of their own race have done the same including some of the nobility who's trying to hurt the current royal family for any little mistake they can find just because they're not in line for the throne if they were then they wouldn't care what he did just as long as he didn't try to be king or unless he had something they wanted.
Katherine had a harder time seducing the prince of the vampire race but she was able to do it but it took her 500 years also she had to be careful not to give away what she was to his family when she met them she always wore stuff to mask her natural scent around them but not him once they started living together she got rid of everything from her assignment the only way she could she burned it in a bonfire then sent her heavy armor and heavy weapons back to her kingdom but kept her sword shield medium armor spear bow and arrow as well as her family clothes.
Once she told him that she was sent here to end the war at first he was going to kill her until she said that it was a seduction mission to end the war peacefully to prove it she kept the paperwork then showed it to him he read everything but other than his name age race and sex she had no information on him just that he was her target after that he burned the documents in the fireplace.
Years later they had 6 children and have just given birth to their 7th child Klaus who is the only hybrid out of the bunch the others are either vampires or werewolves the vampires knew about their relationship at first they didn't do anything when the first two kids were a pureblood vampire and a pureblood werewolf they let it go same with the other children however as soon as they found out Katherine was pregnant again they could immediately tell that this child would be diiferent.
The parents could too so they went to their family homes grabbed their inheritances put them in 4 secret places where no one would ever find them then left clues in every races land including their own but also left a map to find the clues in what will become the world of men also they did something in case something happens to everyone but their last son they created a ring with their combined family crest on it which is the omega symbol to blend in to any environment and they created a necklace with a wolf on it to remind him of his heritage in case he loses his werewolf side they put them on him and spelled them to never come off no matter what also they will size to fit him as he grows.
the day came where their worst fears were realized when Klaus turned 1 year old they were attacked by the vampires captured and killed Klaus was taken along with any valuables they could find which wasn't much other than more weapons and money than they knew what to do with which was fine with them after taking the baby with them along with the dead bodies they did a ritual to forever strip him of his werewolf side they used the DNA of his relatives to do it unaware of what it is they were doing but by then it will be too late.
They succeeded but they also fused his vampire side with that of his fathers and his siblings thus making him 5000 times more powerful than the oldest and strongest vampire alive on top of that he now has all of their powers and abilities the ritual ends also they use his mother and sisters bodies to do something that will also come back to haunt them they make sure that he won't be able to have kids with the other races until after he loses his virginity and is in love with that person they also seal away his emotions so he cant have kids.
Once that's done they give him to someone they trust their best torturer then has him make the infants life hell and it's like this for years even as a teenager he goes through a routine he trains to be a soldier/assassin for everytime he loses in training he gets tortured in the worst ways imaginable until he wins in fact even when he wins they torture him just because of who's kid he is because of his claim to the throne none of this fazes him though he just goes about his day as though nothing is happening.
His hobby is learning new things he wants to learn everything there is but their knowledge is horrible all they have is vampire lore how to use their powers and how to kill someone he easily masters his powers by the time he becomes 13 after that he packs up his stuff sneaks out casts a spell so no one can track him for a month and creates a duplicate of himself then runs away to explore the world.
