Legacies: Everything We Know About The Originals Spin-Off

The The Vampire Diariesshared universe is seeming pretty immortal at this point, considering that as its first spin-off The Originals wraps up, its second spin-off Legaciesis just about to premiere!

While The Originals dove headfirst into the lives of Klaus Mikaelson (Joseph Morgan) and his siblings in New Orleans, Legacies will pick up where that story left off, with his daughter Hope Mikaelson (Danielle Rose Russell) attending a boarding school for magical children in Mystic Falls. There, vampires, witches and werewolves live together in peace, free to be who they are instead of hiding in the shadows. It's a great concept (very X-Men meets Charmed), and we're slowly learning more and more about this exciting new series.

Here's everything we know so far about Legacies and how its first season will unfold on The CW!

It will premiere Thursday, October 25 at 9/8c on The CW. Legacies will be taking over Arrow's spot on Thursday nights. Supernatural will be its lead-in, which could put some good eyeballs on the new series.

The story will center on Hope Mikaelson. Hope's time at school has only been briefly touched on in the fifth season of The Originals, but we'll be living there full time with her on Legacies. She'll face the bullies of Mystic Falls High and the mean girls of the Salvatore Boarding School, plus all the supernatural threats that come with being the tribrid daughter of Klaus Mikaelson.

There will be a time jump. Danielle Rose Russell confirmed at San Diego Comic-Con that Hope will be 17-years-old when the show kicks off, giving it a two-year time jump from the end of The Originals. That will officially make Hope the same age Elena Gilbert (Nina Dobrev) was when The Vampire Diaries launched.

Klaus and the Mikaelsons will not be on the show. Klaus and Elijah (Daniel Gillies) bit the dust -- literally -- in The Originals finale, so they obviously won't be around to visit Hope at her new school, though Julie Plec did tell TV Guide that new series will answer the question of where their souls ended up in the afterlife. None of other cast members of The Originals have signed on to continue their roles on Legacies, meaning Hope's family will be out of sight but not out of mind when the show premieres.

Alaric will be a main character. The Vampire Diaries veteran Matt Davis -- aka Alaric Saltzman, occult expert extraordinaire -- has signed on as a series regular. As headmaster at The Salvatore Boarding School for the Young and Gifted, Alaric will play a major role in the series, in much the same capacity as he did on The Vampire Diaries. It's always good to have an expert in the spooky stuff hanging around.

Alaric and Caroline (Candice King) and Alaric's twins will be part of the show too. Josie and Lizzie Saltzman also attend Hope's boarding school, and they've got a bit of a mean girl reputation. Don't worry, though, The Vampire Diaries fans will remember that Caroline Forbes also started out as a mean girl before the show developed her into a complex and incredibly beloved character.

Lizzie in particular will have a lot in common with her mother, Jenny Boyd told TV Guide. "I've really tried to sort of bring that out in her and adopt some of those similar characteristics because Lizzie really does identify Caroline as being her mom and feels very close to her," Boyd said. "She has a lot of similarities in personality, but then she's also very different. I think she's got a more volatile side, to put it in those terms. She's very emotional and she's dealing a lot of very strong feelings. She's very vulnerable, and she's not so good at hiding it."

Caroline will be off on a mystery mission. While Caroline will be mentioned in the series, she won't be at the school, and she'll even end up missing her daughters' birthday. "[The twins] believe she's off on recruiting missions, and Alaric knows that she's actually off doing other things that have to do with the longterm survival of their daughters," Plec said. "So the mystery of 'Where is Caroline? Why isn't she coming home for their birthday?' that kind of thing is going to be part of our story in the hopes that one day we'll be able to have her walk through the doors as well."

Vampire Diaries guest stars are already locked in! Julie Plec confirmed at San Diego Comic-Con that Sheriff Matt Donovan (Zach Roerig) will appear in the Legacies pilot this fall. It's also been confirmed that Jeremy Gilbert (Steven R. McQueen) will appear in the third episode of the season.

The Salvatore School has a rivalry going with Mystic Falls High. The kids of Mystic Falls High think the Salvatore School for the Young and Gifted is basically a troubled rich kids school, but they have no clue it houses some of the most dangerous magical teenagers in the world. Resentment has built between the two schools over the years, which we're sure to see culminate in the town's annual flag football game that will take place in Episode 2.

According to Julie Plec, the Salvatore School kids have one responsibility in this game: Lose spectacularly or risk revealing their powers. Hard to do if the bullies of Mystic Falls High have anything to say about it. "This bully and this mean girl are just poking and poking and poking, and so our kids really have to, like, you know... control themselves," Plec teased. "And, you know, that, of course, goes terribly wrong."

There will be a a bunch of new, original characters at the school. Lots of familiar faces will pop up in Legacies, but that doesn't mean we'll be devoid of shiny new faces. Classmates will also include a hot werewolf with anger management issues named Rafael (Peyton Alex Smith) and will be a male vampire named M.G. A townie, Landon (Aria Shahghasemi), will also catch Hope's eye. And that's only a few of the many new characters heading our way!

Legacies will have a monster-of-the-week format. Legacies won't just be introducing new supernatural creatures we've never seen before; the show will actually be implementing a monster-of-the-week format that will establish a more procedural nature to the show.

No Salvatore children will appear. Damon (Ian Somherlader) and Elena may have lived happily ever after, but don't expect them to send their kids to the Salvatore Boarding School. Sorry!
