In honor of Game of Thrones season seven finale, Facebook has debuted a feature that lets fans know how to transform themselves into the dreaded Night King.

To access the new Night King camera effect, simply tap the camera icon on the top left corner of the Facebook app or swipe right from the News Feed page to open the camera. From there, you’ll be able to experience exactly what it feels like to sport the “icy visage” of the leader of the White Walkers.

By creating a Night King video, you’ll join the ranks of Thrones‘ very own Kristofer Hivju — who plays Tormund Giantsbane. “Sunday is the last episode of season seven,” Hivju menacingly intones as the undead villain.

Watch the clip below.

“The Dragon and the Wolf,” the finale of Game of Thrones‘ seventh season, airs Aug. 27 at 9 p.m. on HBO.
