Innistrad: Midnight Hunt is the 89th Magic expansion. It was released on September 24, 2021, and is paired up with Innistrad: Crimson Vow which releases two months later.
The set was originally announced with the provisional name Innistrad: Werewolves.

For the Midnight Hunt storyline R&D wanted to reset Innistrad to the "2011 version where horror monsters from classic horror films are menacing humanity and who is going to protect them? because Avacyn is dead now" and without Avacyn's protection the humans have to "turn to older, and perhaps darker forms of magic to stave off the onslaught of the different monsters, most particularly the werewolves" who have gone "plumb loony." Midnight Hunt begins the new story ripped right from the worries of Innistrad's populace: a night that may never end. With the sun rising later and setting sooner each day, they turn to the hope of the Harvesttide festival and a ritual with warlocks to maintain the balance. Despite plenty of werewolves and other denizens of the night, there's strength and hope for the humans gathered deep in the woods of the Kessig countryside.

The first chapter of the Innistrad: Midnight Hunt story was posted to the Magic: the Gathering website on September 2, 2021. The storyline began in Midnight Hunt will be continued with Innistrad: Crimson Vow and both stories "revisit what we learned first about Innistrad, showing us again why the wisest humans there never stop fearing nightfall."
