The search for the Infinity Stone was a major part of Avengers: Infinity War, and a lot of films in the Marvel Cinematic Universe have featured the powerful stones in some way. In the MCU, the stones -- which have some level of sentience -- were created by cosmic entities predating the universe itself. However, one of the Infinity Stones might be more important than any other: the Mind Stone.

The Mind Stone has been a major driving force behind the events of the MCU. Thanos seems to have possessed the Mind Stone, which he then gave to Loki. That act set many of the events of the MCU into motion and eventually resulted in the creation of Vision. Additionally, a recent comment from Marvel Studios suggests that Loki might have been being influenced by the Mind Stone during the events of Avengers, leading further credence to the idea that the stone is purposefully manipulating events.

The Infinity Stones will certainly play an important part in the upcoming Avengers: Endgame. Although it's not clear at this time how the Avengers will defeat Thanos, a lot of fan theories figure that time travel will play a major role. Some fans have speculated that Doctor Strange's penchant for using the Time Stone to meddle with time travel might also come into play.

Although Loki appeared to die in Infinity War, a lot of fans figure that the villain-turned-hero will return in the future. Disney+ is also intending to make a series focused on Loki, though it's not clear where that project will take place in the timeline.
