The narrative follows the overarching saga of these characters.
The series debuted in 2011 and features ties to classic fairy tales.
Problem: The provided sources do not contain a summary of the Season 5 narrative arc. They only mention the total episode count (23) and general series premises.
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES." "If a detail is not in the provided material, you omit it rather than guess."
Conflict: I need to write 160-220 words, but the source material is extremely sparse regarding Season 5 specifically. It only says "Once Upon a Time Season 5 continues the overarching saga across 23 episodes."
If I write only what is in the source, I cannot reach 160 words.
Let's re-read the sources carefully.
