One of the six Infinity Stones created by the Cosmic Entities, the Reality Stone possesses the power to bend the very laws of reality and physics, converting matter into dark matter. While normally a stone, it can turn into a flowing liquid or mist and came to be known as the Aether. The Dark Elf Malekith attempted to use the Aether on two occasions to rewrite reality during a cosmic event called the Convergence and failed by both counts. Currently, the Aether is in the possession of the Collector after the Asgardians entrust the item to him.
