The Threat of the Dark Dimension - 2016
For untold millennia, the Sorcerers Supreme had kept the dimension safe from mystical threats. But the Ancient One unwisely allowed several of her students to steal notes from the Book of Cagliostro, and - under the leadership of Kaecilius - they opened a portal to the Dark Dimension. Empowered by Dormammu, these Zealots attempts to tear down the barriers between the dimensions. The Ancient One herself died to oppose them. Fortunately, new sorcerer Stephen Strange was able to use the power of the Time Stone to defeat Dormammu, forcing the cosmic being to end his attack on Earth.
The history of the Sorcerers Supreme remains a mystery. Given they were actually aware that the Power Stone was hidden on Morag, it's possible that this order was actually formed back when the Celestials were defeated millennia ago.

A Storm is Brewing on Earth - 2017-2018
An uprising on Attilan led the Inhuman Royal Family to ultimately destroy their home. The Inhumans of the Moon traveled to Earth, seeking to forge a new society here. They presumably chose an isolated location, as there has been no mention of these Inhumans since. In Los Angeles, the Pride's plans fell apart when their children began to discover the truth. The children wound up becoming runaways. Meanwhile, in New Orleans, Roxxon's attempts to tap into new energy sources almost caused a disaster. The crisis was averted by two teenagers, Tandy Bowen and Tyrone Johnson, who had been empowered as the "Divine Pairing."
Steve Rogers, Falcon and Black Widow continued to act as independent heroes, traveling the world and dealing with crises as they encountered them Ant-Man and Hawkeye returned to America, signing plea bargains and being placed under house arrest. Tony Stark gave up on the Avengers Initiative, and instead focused on creating new tools that he believed would be essential in the defense of Earth. He blamed himself for losing focus over the years, and resolved to create a defense to protect the planet from alien threats.
Coulson and his S.H.I.E.L.D. team returned from a dystopian future, one in which the world had been shattered like an eggshell, and resolved to save the planet. They soon uncovered the last Hydra conspiracy, headed up by General Hale, who was seeking to create a super-soldier to protect the world from the threat of Thanos. General Talbot was ultimately transformed into Graviton, a powerful being able to manipulate gravity.
Scott Lang was broken out of house arrest by the Pyms in order to help rescue Janet Van Dyne from the Quantum Realm. They were successful, and Janet used her powers to heal Ghost from her intangibility.
The Fall of Asgard - 2017-2018
After two years seeking out the Infinity Stones, Thor returned to Asgard, and discovered that his brother Loki was masquerading as the All-Father. The two brothers returned to Earth, only to bear witness to Odin's death. That death unleashed Hela, who used the Rainbow Bridge to travel to Asgard. She cast Thor and Loki to the planet Sakaar, where they allied with the Hulk and a group of revolutionaries in order to return to Asgard.
Hela proved too powerful, and Thor realized there was only one way to defeat her; to cut off the source of her power. He incited Ragnarok, destroying his own homeworld. Only a small number of refugees escaped aboard a single vessel. In the final, ominous scene set seconds before Avengers: Infinity War, this vessel was confronted by the Sanctuary II, the ship of Thanos himself.

Thanos Triumphant - 2018
Thanos, last survivor of Titan, finally launched his insane campaign to "rebalance the universe." He and his Black Order razed Xandar, claiming the Power Stone, and then intercepted the Asgardian refugees to capture the Space Stone. Thanos then divided his forces; while he traveled to Knowhere in order to acquire the Reality Stone, he sent the Black Order to Earth in pursuit of the Time Stone and the Mind Stone. This brought them into conflict with the Avengers.
With the threat of Thanos more real than ever before, Graviton attempted to boost his powers by absorbing more Gravitonium into himself. This act would actually have destroyed the planet, but Graviton was successfully stopped by S.H.I.E.L.D..
Thanos forced his daughter Gamora to reveal the location of the Soul Stone, and sacrificed her in order to acquire it. Three of Earth's heroes battled him on Titan, but Doctor Strange was ultimately forced to surrender the Time Stone. With only one Infinity Stone left to acquire, Thanos himself headed to Earth, where the assembled Avengers were battling the Black Order in Wakanda. In spite of the Scarlet Witch's best efforts, Thanos successfully acquired the Mind Stone, killing Vision. He was able to use the Infinity Gauntlet to wipe out half the life in the universe with just a snap of his fingers.
