Thor: The Dark World

Thor sequel built around the Aether, later revealed as the Reality Stone; its mid-credits scene hands the Aether to the Collector, setting up Guardians of the Galaxy. Disney+'s official timeline places it directly after The Avengers, since it opens with Loki's trial, so it sits before Iron Man 3 in chronological order; Marvel's print timeline flips the two, so either order works.
