We still have two hours of magical adventures before Once Upon a Time Season 3 comes to a close, but in the final minutes of the finale, we're supposed to learn where the story is headed next. We saw Neverland and Oz this year, so which fantastic world is next on the list?

The showrunners are keeping totally mum, of course, but they did tease to The Hollywood Reporter that next year's story is something they "cannot wait" for, and added that "there's  really no way to tease it beforehand without giving it away."

What world could it be? The possibilities are really endless, but here are some guesses about famous story locations that could pop up in Season 4.

Agrabah. We've already been introduced to Aladdin's world on Once Upon a Time in Wonderland, but we have yet to meet Aladdin, Jasmine, or really any of the iconic characters from that story other than Jafar. We wouldn't be surprised if the writers wanted to mine the world further, and we'd certainly be excited about it.

Narnia. The show has slipped some subtle references to Narnia in before, including the recent use of the "door to nowhere." This is a rich and beloved world that we're sure would be fun to explore. Our question is, could the show get the rights?

Camelot. Given that Lancelot existed in the Enchanted Forest, we're pretty sure Camelot is another kingdom in the same world, but it could be very far off and very different. We'd love to see OUAT's take on the King Arthur tales.
