The Casket of Ancient Winters was an Asgardian artifact, which contains the Fimbulwinter of Ymir; it created massive snowstorms if opened. The hand size Casket of Ancient Winter contained the fury of a thousand killing winters. It was used by Surtur in his attempt to defeat Thor.
Surtur unleashed the devastating power of this artifact on the planet Earth. Needless to say, this event caused mass-hysteria. Thor with the aid of Earth's heroes was able to defeat Surtur and safeguard the Casket so that it could not be misused again.
Sometime later the Casket mysteriously appeared in the possession of the Dark Elf, Jagrfelm. Before he had the chance to use it for his own purpose, he was slain by the leader of the Dark Elves Malekith the Accursed. Malekith used the Casket to wage war on Asgard.
In this battle, he was able to bring the Mystical Kingdom down to its knees. The power of the Casket reached the realm of Hel, causing concern of Volla and Hela. The cold was so permeating that the strongest of the trolls Ulik was overtaken by this calamity. It even incapacitated the Frost Giants themselves.
There seems to be no cure to its effects, until the Lady Sif recalled the secret Gem of Infinite Suns. This was concealed in Odin's personal treasures. Thor retrieved the Gem and used its mighty powers to right the wrongs caused by Malekith. Once everything was returned to its natural state, Thor sent both the Casket and the Gem into an unknown dimension. Only time will tell if we will ever see either the Casket of Ancient Winter or the Gem of Infinite Suns again.

The Casket of Ancient Winters was long held in the possession of the jotuns until it was wrested from their grasp by the Asgardians in 965 A.D. during a battle in Tønsberg, Norway. It was then secured in Odin's vault where it remained for over a thousand years until Loki removed it for use as both a weapon and a bargain chip in a bid to gain a kingdom of his own. Loki then froze the Bifrost Bridge open with the Casket's power, so that the Bridge's energy would build until it destroyed Jotunheim, intending to please Odin and be named the rightful heir of Asgard. When Thor destroyed the Bridge with Mjolnir to prevent this from happening, Loki willingly fell into the black hole left behind. The Casket was later returned to Odin's Vault and was most likely destroyed when Surtur razed Asgard.
