I thought it'd be prudent and helpful to list everything that we currently know about Season 7:
- The season's primary narrative will focus on Henry (Andrew J. West) and his daughter Lucy (Alison Fernandez) and their quest to restore hope, aided by Captain Hook (Colin O'Donahue), The Evil Queen (Lana Parilla), and Rumplestiltskin (Robert Carlyle)
- Jennifer Morrison will reprise her role as Emma Swan in the first episode of the season
- Ginnifer Goodwin, Josh Dallas, Jared Gilmore, Emile de Ravin, and Rebecca Mader have stated that they are all willing to return to the series in a guest-starring capacity if/when the narrative calls for it, something which has also been corroborated by Adam and Eddy
- The first episode of the season will introduce us to Lucy's mother - who will be a fariy-tale character - and set up/establish the "epic true love" between her and Henry
- The season will begin with Hook, The Evil Queen, and Rumple having fallen victim to a brand-new Curse that will see them trapped in a brand-new location under new false identities
- The season will see the introduction of brand-new story realms and fairy-tale characters, and the return of old characters
- Filming on the season begins in July, and additional Series Regular casting news should be expected at some point between now and then
- The season's narrative is very much informed by what happened in Seasons 1 through 6, with Adam and Eddy beginning to discuss narrative possibilities for where they could go with the series beyond Season 6 nearly a year ago
