A Harry Potter play is coming Off-Broadway. No, not that one.

An alternate history Harry Potter play — Puffs, or: Seven Increasingly Eventful Years at a Certain School of Magic & Magic — is headed Off Broadway following a well-received debut run at the Peoples Improv Theater last season.

The completely unofficial play, written by Matt Cox and directed by Kristin McCarthy Parker, follows a gang of Hufflepuffs as they experience seven should-have-been-average years at Hogwarts as outsiders to the drama instigated by a certain golden trio. (Of course, names must not be named, since this is purely a Potter parody.)

The show, produced by Tilted Windmills Theatricals, will end its sold-out run at its current home at PIT on Aug. 4. The “enhanced” production opens at the Elektra Theater (famously, the former home of a long-running Silence of the Lambs musical parody) on Oct. 20; previews begin on Sept. 29.

Part of the show’s logline sums up the hilarious premise: “Some people rise from humble beginnings to defeat the forces of darkness in the face of insurmountable odds. Puffs is the story of the people who sit in class next to those people.”

The cast includes Langston Belton, Madeleine Bundy, Jessie Cannizzaro, Nick Carillo, AJ Ditty, Julie Ann Earls, Andy Miller, Zac Moon, Ellie Philips, and Stephen Stout.
