The first half of Once Upon a Time Season 3 took us to Neverland, but when the show returns this March (momentary pause so that you can tear your hair out about the wait), we'll be back in the realms we know and love: our world, and the Enchanted Forest. But that doesn't mean we can't have a villain from a different land!

As the winter promo revealed, the second half of Season 3 will see our heroes facing off against none other than one of the most classic storybook villains: The Wizard of Oz's Wicked Witch of the West, who will be played by Lost alum Rebecca Mader.

We don't know much about this villain, but a new teaser promo for the season has us desperate to learn more.

This simple 13 second promo doesn't dish new info, but it certainly makes the witch seem imposing. In it, we see her walking towards Storybrooke (does that mean it's back? We're guessing — and hoping — that the town isn't really gone for good). It's night, and she cuts an intimidating figure in a dramatic dress. Then she turns to look over her shoulder, and we see her green-skinned profile. "Wicked is coming" scrolls across the screen.

We. Can't. Wait.

Catch the Once Upon a Time Season 3 winter premiere on Sunday, March 9 at 8 p.m. ET/PT on ABC.
