Infinity Stones

The Infinity Stones are six objects of great power (though, currently, only four are known of or mentioned) from the Marvel Cinematic Universe Created by the Cosmic Entities They were made before time began. When the six stones are combined, they power the Infinity Gauntlet, a glove that gives its wearer power beyond comprehension.

The Aether is a red liquid used by Malekith. Its equivalent in the comics is The Reality Gem.

Trivia

 * Fans have speculated that the Aether is the Reality Stone.
 * The post-credits scene in Thor: The Dark World reveals that the film's central weapon, the "Aether", is one of six "Infinity Stones", and that the Tesseract from the previous films Captain America: The First Avenger and The Avengers is another. It is also noted that it would be unwise to keep two of the stones in the same location.
 * Kevin Feige has stated that one of the Infinity Stones will be featured in Guardians of the Galaxy stating: "You may see another infinity stone in Guardians and certainly fans of the comics know what one can do with all of those stones if, god forbid, they get them and with Thanos showing up at the end of The Avengers, he plays a part in Guardians and leads us towards at least one potential future."
 * It is possible that the Soul Stone could connect to Marvel hero Adam Warlock. Warlock's cocoon was briefly shown in Thor: The Dark World, as well as Guardians of the Galaxy.
