Three years ago, a meteor landed on a coastline in the United States. Ever since that day, a strange disturbance known as the Shimmer appeared. In response, many expeditions have been carried out by the army, though only one person has ever returned from them: a man named Kane. Upon returning, he reunites with his wife, Lena, but is unusually evasive when asked what happened during his expedition. Shortly thereafter, his health begins to deteriorate and is quickly hospitalized. With Kane in intensive care, Lena is approached by Dr. Ventress. She is prepared to go on a new expedition into the Shimmer. Determined to learn what happened to Kane, Lena volunteers to join her.
In the distant past, Bor, the father of Odin, faced off against Malekith. The leader of the Dark Elves sought to unleash a weapon called the Aether on the Nine Realms before Bor handed him a crushing defeat. Following his victory, Bor secured the Aether in a stone column, though Malekith and a portion of his forces manage to escape.
It is now the year 2013 and Loki, the adopted son of Odin, stands trial for instigating a coordinated attack with the Chitauri in New York City one year prior. Meanwhile, the Bifröst has been recently reconstructed, causing no shortage of turmoil in the Nine Realms. Thor, along with Frandral, Volstagg, and Sif, repel an invading army on Vanaheim. After achieving victory, Thor and his comrades learn of the Convergence – a rare event in which the Nine Realms align. This causes interdimensional portals to appear at random. One such portal happens to be in London, England on Earth, drawing the attention of Dr. Jane Foster.
In the year 965 A.D., a fierce battle was waged between Odin, the king of Asgard, and the Frost Giants of Jotunheim. The Frost Giants’ leader, Laufey, would stop at nothing to conquer the nine realms, intending to start with Earth. Before his ambitions came to pass, the Asgardian warriors defeated the Frost Giants in in Tønsberg, Norway. In doing so, they seized the source of the Frost Giants’ power: the Casket of Ancient Winters. It is now the year 2011 and Odin’s son, Thor is prepared to ascend to the throne of Asgard. However, after hearing about the Frost Giants’ desire to reclaim the Casket, he, without Odin’s knowledge, travels to Jotunheim to confront Laufey. Assisting him are his brother, Loki, childhood friend, Sif, and the Warriors Three: Fandral, Volstagg, and Hogun. Though he is doubtlessly brave for his efforts, Thor may suffer a dire consequence for his rash actions.
