here is a more updated clearer version of the middle vampire's story:
Daniel Edgar:
he was born around 1795
He was a very studious and serious gentle colt who prefers books and getting work done then to have fun.
When he was a pony; He was just like everypony else. He hung out with friends akin to himself but not too often.
He read many books, likes to get his school work done, and turning them in good time. Mares were interested in him though he was too; his work was of more importance.
When he was 31 in 1826, he met a mare who seemed attracted to him.
He was captivated by her beauty. Yet he was more focused on his studies. Thus he ignored her.
The mare was a purple earth pony when she talked, she showed slightly large sharp teeth, and she was pale. She was kind and helpful pony though soon she was following Daniel around without him knowing.
One night before he went to bed he saw fog come into his room, Daniel ignored it thinking it was nothing and it will go away later, then he felt a sudden urge to wake up and look in front of him.
It was the mare he saw before he scolded her demanding why was she in his room, the mare hypnotized him then the mare revealed herself to be a bat pony a vampire bat pony!
She moved in closer to him, kiss him, and then bite his neck and drank his blood. The next morning the mare was gone, Daniel as well.
His family mourned for him as well as his friends when they found out the news; they all assumed that he caught something together with not saying anything to spare their feelings or thought he can handle it and burred him.
Later that night, Daniel woke up and dug himself out of the grave and soon realizes he has become a vampire.
Time passed there was a vampire party (not the ball but a small party) that he was invited to when other vampires found out he was one of them, Daniel talked to other vampires eventually one asks him if he would like to join them.
They are a small group who know that instead of being isolated or only living in small family groups with guards, they started a society so they can work together, they know that Daniel can be useful.
Daniel, with no other place to go accepted the offer. The group was genuinely nice ponies though now they must be kept secret, Daniel ends up living with them.
He was a Pegasus.
———————————————————————————————————————————————————————————————————— ———————————————————————————————————————————————————————————————————— she was born in 1819
Charlotte was a very kind, elegant, fashion-loving earth pony.
She lived in a wealthy family and love being with her friends; she will help ponies who are in need.
She feels like this world is only full of purity and wonderful ponies, one day at the age of 20 she met a very handsome yet pale orange stallion who was a gentle colt to her and who was very kind, it seemed like love at first sight.
They went on rendezvous such as dinners, shows, and a walk at the park.
One day her boyfriend wanted to go somewhere quiet and private wherefore they can be together and plan on what to do next.
She agreed though she felt that it seem strange to move somewhere quiet in the street.
Once they were in the passageway, Charlotte became hypnotized; the stallion told romantic things to her.
She smiled the stallion leaned in and bit her neck.
The stallion turned out to be a vampire.
Later in the morning, she was found dead, the stallion was gone later she was buried Charlotte dug herself out and cried.
Months later after meeting some mares who were vampires also, they became friends, she already accepted the fact she was a vampire seeing that there are some benefits, Charlotte still missed her old life though with the help of her new friends she got to try unusual foods (not just blood) and lived far away from her old home to live in a house.
In 1839 one of Charlotte's vampire friends invited her to a vampire ball (what happened next I'll explain later)
the blue one is named Joseph Henwood age 40 born 1755
He is a kind, handsome though intimidating stallion (earth pony).
He had a loving family, but his father was a soldier for their area (the mayor was very paranoid).
He wanted to be like his father; consequently, he became strong, got angry, hung out with mares as well as his soldier friends.
They all acted like bullies (not all soldiers are like this) they make fun of weaker or new ponies who had to or want to become soldiers along with the fancier ponies.
One day he was making fun of a pale appaloosa (not the town but the type of horse or pony) noble stallion, simply that stallion seems to think his wife might be hungry he told her what happened thus sent her off.
Soon she found Joseph and seduce him then bite his neck he was gone.
His family and friends knew and were upset; some soldiers were also morning, Joseph then woke up that night.
He later dug himself out was extremely angry and upset about what happened to him.
Some days later he got into a fight with a random vampire, the vampire soon saw that Joseph was like him too and try to make amends though Joseph did not trust him well yet the vampire proves to him that he is to be trusted and explained that he is wealthy, he lives with his wife and fouls he wants him to be his second guard. Joseph still did not believe him.
The vampire has to show him.
The vampire grabbed him and took him to his house; Joseph was now convinced and joined the vampire and his family with his new vampire guard teacher. It all happened during the 1790s.
how they all met: in 1839 there was a beautiful, elegant vampire ball there was dancing, music, blood from animals, and strangely meat and vegetables.
Not every single vampire was there only the ones nearby or close to it.
Daniel met Joseph because Daniel wanted to talk to him and make friends.
Joseph spoke to him they had a good time until Joseph saw Charlotte and ask Daniel if he wants to help in getting acquainted with her, maybe he could help Daniel in getting a mare too.
Daniel was nervous but accepted the offer because he thought maybe not all vampire girls are like the one he was with before, they both went to Charlotte.
Charlotte showed that she was shy and a bit scared but gave them a chance and had a wonderful time.
Joseph and Charlotte became friends Charlotte might find a stallion to love yet she's not ready for it now, to the disappointment of Joseph but he got over it Daniel also does not seem prepared to be with females but he might one day.
Vampires had several balls from time to time, that is how they all met and joined the society
I also change it to them being helpers of the founder but they also helped to make the society official
