Marvel Comics’ six Infinity stones were the very reason behind the events of the Infinity War. These stones have been the reason that so many lives across the entire universe have been lost. Every stone is known to control one aspect of the Marvel universe – Power, Soul, Space, Reality, Mind and Time. When they are put together, these stones give the wielder the powers and abilities of a God. That is exactly what the Mad Titan, Thanos had made so formidable in the movie, Avengers: Infinity War.
There had been no official confirmation from the team at Marvel Comics as to how these Infinity Stones were created and how they became a part of the universe. With the release of Infinity Wars #5, the fans now have an idea of how these stones had been created and shaped the future of the entire Marvel universe. In the mainstream universe, the Soul Stone had been the only one that had an origin story of sorts. The back story of these stones had been recently released after the Asgardian God of mischief, Loki, had decided to explore another universe.
In the 5th issue of Infinity Wars, Loki is seen backstabbing his team of Infinity Watch and then steals all the six Infinity Stones from Gamora in the Soul World. Loki then uses these stones for travelling to the end of time, and he believes that this is where he can gain access to unlimited energy and also become a huge cosmic entity. Loki then lands on a location called Quarry of Gods, and here, he makes a very startling discovery.
These Infinity Stones had been just the first batch of their kind. At the end of time, many of these rocks exist, and they had not been created, but they had been mined. A group of Celestials were mining these stones from the Quarry and also seeding them in alternate realities and different universes.
Loki learns that the race of Celestials are Gods of the Marvel Multi-Verse and they have manipulated everything from the start. Loki then demands answers, but this issue ends right before he can get any.
Loki had last made an appearance in the movie, Avengers: Infinity War and the official synopsis is as follow:
Iron Man, Thor, the Hulk and the rest of the Avengers unite to battle their most powerful enemy yet — the evil Thanos. On a mission to collect all six Infinity Stones, Thanos plans to use the artefacts to inflict his twisted will on reality. The fate of the planet and existence itself has never been more uncertain as everything the Avengers have fought for has led up to this moment.
