ONCE UPON A TIME - ABC’s "Once Upon A Time" stars Andrew J. West as Henry and Dania Ramirez as Cinderella. (ABC/Eike Schroter)"A new book opens this fall" when "Once Upon a Time" returns -- and moves to Seattle. (ABC should just go ahead and do a "Grey's Anatomy" crossover.)

"Once" is now at San Diego Comic-Con, after revealing tons of intel last weekend at Disney's D23 Expo. Today, Comic-Con attendees got to see the first teaser for OUAT Season 7, which ends with the premiere date: Friday, October 6. Yep, new day. No more Sundays.

ABC has yet to post this promo themselves; instead, it was sneakily shared by a fan, then picked up by SpoilerTV and TVLine:

More details should be coming out this week, but you can catch up on the new Cinderella, young and adult Henry, and a possible Captain Swan baby, in the D23 news roundup.

The Season 7 premiere is called "Hyperion Heights," which is also the name of Henry's new neighborhood in Seattle, and now we know it'll arrive on Friday, October 6 at 8 p.m. on ABC.
