The final trailer of Fantastic Beasts: The Crimes of Grindelwald has arrived, giving us a dark look at the magical forces that lurk outside the walls of Hogwarts. 

We see Grindelwald (Johnny Depp) in action, recruiting his team in Europe to take over the world of non-magical beings, aka muggles. The biggest reveal is Claudia Kim playing Nagini, who die-hard Harry Potter fans know well as Lord Voldemort’s trusted snake and Horcrux. But Nagini isn't yet the villain she'll eventually become, as she told Entertainment Weekly, but a human “Maledictus” who we see performing for muggles as part of the Circus Arcanus.

“It will be so interesting to see another side of Nagini,” Kim said. “You’ve only seen her as a Horcrux. In this, she’s a wonderful and vulnerable woman who wants to live. She wants to stay a human being and I think that’s a wonderful contrast to the character.”

This new trailer also includes a flashback of Dumbledore (Jude Law) and Grindelwald while they were students. Meanwhile, Newt Scamander (Eddie Redmayne) finds himself in back allies of the wizarding world and dark corners of Paris to fulfill Dumbledore’s mission. When told by his brother, Ministry Auror Theseus, “The time is coming where you’re going to have to pick a side,” Newt fires back, “I don’t do sides.” We’ll see about that, Newt.  

The Crimes of Grindelwald is the second film of a five-part series. In addition to Redmayne, Law, and Depp, the movie stars Katherine Waterston, Dan Fogler, Alison Sudol, Ezra Miller, Zoë Kravitz, and more, with Potter author J.K. Rowling potentially scripting every one.

The Crimes of Grindelwald hits theaters Nov. 16.
