"Once Upon a Time" has called the charming Dan Stevens swoon fans by narrating a series special, according to E! News. 

This Sunday, lovers of the modern fairytale series can tune into "Once Upon a Time: Wicked is Coming," which is an hour-long special to get them back into the loop of what's been going on with Storybrooke after a long hiatus. The special will also give viewers a behind-the-scenes look at what's next for the series.

Stevens will take us through this all inclusive catch-up, which will feature interviews with members of the cast, along with "Once Upon a Time" creators Eddy Kitsis and Adam Horowitz. 

This isn't the first time Steven's done a voiceover. He's also the voice of TIM, the super-computer of CW's drama "The Tomorrow People.

"Wicked is Coming" will help sort out the huge and tangled family tree and highlight our favorite heroes' journey from the beginning. Stevens will also recap Peter Pan's plots from Neverland, which will lead up to the midseason premiere and the debut of Rebecca Mader as Zelena, the Wicked Witch of the West.

Once Upon a Time: Wicked is Coming will air this Sunday at 7 p.m. on ABC. Be sure to brush up on your fairytales.
