I have a fair few that might be intersting, im making more so there will be others later lol.
Soooo here we go.
So first we have
Alexander Duncan he is the son of Albus Dumbledore and Gellert Grindelwald, DNA was taken from both men and a kid was created in a woman yadda but anyways. He is a writer, does not go out a lot, but when he does its to cause havoic or to get some sweets at Honeydukes. He is the rising darkness that is going to cause issues with the games and everything but right now he is biding his time. I don't know how much interaction there will be, sometimes i just throw people in if the other wants to think of something, so there is Alexander.
Next we have,
Bellatrix Lestrange , even people from the states know the Black, Lestrange, Malfoy fams because of some of the shit that they get up to, and none so much batty as Bella herself. Anyways, shes not as bad as she is in the books, shes still crazy, still a pureblood nut job, will be working with Alex but not Voldemort obsessed because he is not around, Tom is but not as Volde, so if they did have a run in could be fun.
Next,
Castor Black he is one of a set of first year twins to Sirius Black and his late wife, she died, the boys said something and sirius hit them, saw what he had done, packed them up and left them with their Uncle Remus. They are first years, and Castor is gay as the sun shines, super, super sweet and a little shy. Could be fun if they met since he likes meeting new people and Is would be really new from a new country and all.
Next
George Weasley , one of the king of pranks who runs the shop with his brother. There will be times that the students from the others schools might be allowed to be taken to Diagon Alley, it would be fun to see if the two run into each other and how they would interact with each other.
Next we have
Gwendolyn Winters well shes a bit of a odd duck, but she is at the school sometimes taking things from the shop to the school for the Quidditch team to use and such. So if he is ever around the pitch they might bump into each other.
then
Juniper Danathor is from the french school that i wont butcher the name and too tired to look it up ahah, but she is from there, she as well has spent some time finding hiding spots around the school so that she can get away from the others. She is kind, understanding and a good person to talk to when there is a bit of a bother going on.
Then there is
Lily Evans who is going through a bit of a rough time, James is an abusive dick who hates their youngest son because he is gay, and Lily is not having any of that, so she has left James, is now working at Honeydukes, and has moved the kids in with her and is dating Snape yayyayya. Anyways if he comes into her shop, she will treat him very kindly.
then
Lyra Malfoy is a self obsorbed pureblood Malfoy, younger sister to Draco and twin sister to Abraxa. She is betrothed to a Potter cousin, and is quiet happy about this because shes getting a puppy out of it as well. She hates mudbloods, she wont do to well around him if she finds out that he is a werewolf as she finds them less then human, so there could be some fun anger here.
Next
Remus Lupin a well known werewolf and right now the uncle to the Black boys and making sure that they are alright, and that they always have a safe home and trying to find Sirius and make him come home as well. He is also madly in love with Sirius but feels there is never going to be anything back so he is a bit on the sad side with this. Other then that, if they run into each other, they would know that the other is a wolf, they coul have many a conversation with this.
Lastly
Xavier Carrow betrothed to Abraxa Malfoy, a Auror in Training and a bit of a horn dog dick. He spends a lot of time in Hogsmeade just to be close to where she is, also hates being at home around his mother that is why he got a job in the first place lol. Snobby, bratty, thinks he is better then most, part of the sacred 28 and loves it.
so there we have it, if you have ideas leme know.
Plenty of room for OCs
