The Marvel Cinematic Universe has spent the past eight years and 12 movies slowly setting the stage for a showdown with Thanosthe ultimate villain of the Marvel comic books, in Avengers: Infinity War. And as any comic book fan will tell you, Thanos’ most famous plan involves collecting the six Infinity Stones, creating the Infinity Gauntlet, and dominating the entire universe as a god-like being. If that sentence sounds a little confusing, don’t worry. A new featurette is here to offer you a much-needed assist.

Although this video doesn’t offer much new for serious Marvel nerds, this is required viewing for the more casual MCU fans. Here’s the basic gist – the six Infinity Stones are the most powerful objects in the universe, four of them have shown up in past Marvel movies, and Thanos wants them very, very much. To have them all is to gain supreme power and so on. The upcoming two-part Avengers: Infinity War will deal with exactly what transpires when Thanos gets his wish. For homework, go read the famous Infinity Gauntlet storyline to get a taste of what might go down.

Or, you know, just watch this featurette and wait for the movie. We won’t judge you.

This featurette does finally and officially confirm the exact identities of each stone seen in the MCU so far. The Space Stone is the Tesseract, previously seen in Captain America: The First Avenger and The Avengers. The Reality Stone is the Aether, introduced in Thor: The Dark World. The Power Stone is the purple gem housed by the Orb in Guardians of the Galaxy. The Mind Stone was embedded in Loki’s staff in The Avengers, but now it resides in the Vision’s forehead, as seen in Avengers: Age of Ultron. We still haven’t seen the Time Stone or the Soul Stone, but both seem like worthy candidates to pop up in Doctor Strange.

But with each Infinity Stone stashed away in a different place, the big question now is how Thanos is going to go about collecting them. Will Avengers: Infinity War Part 1 open with a heist montage? We certainly hope so.
