Need some cliffs notes to connect the new Fantastic Beasts: The Crimes of Grindelwald to the original Harry Potter films? Yeah, me too.

With a mythology this dense, it’s hard for mortal muggles to maintain an encyclopedic recall of every detail, even some of the big ones.

This new promo from Warner Bros. helps connect the most important dots, including facts involving young Dumbledore (Jude Law), the villainous Grindelwald (Johnny Depp), the Sign of the Deathly Hallows, and more.

Fantastic Beasts: The Crimes of Grindelwald opens worldwide on November 16, 2018.
