"No, we can't give the Reality Stone to Asgard," Stephen Strange warned firmly. In Stephen Strange's precognitive dreams, Asgard had won the war against the Dark Elves and successfully obtained the Reality Stone. But Odin knew that keeping two Infinity Stones together would draw the attention of cosmic powers and endanger Asgard. He also knew that the power of the Infinity Stones would eventually lead people into irreversible ruin. So Odin ordered Sif to take people and deliver the Reality Stone to The Collector for safekeeping.
