The group eventually discovers that a figure named the Snow Queen (a more faithful adaptation of the original fairy tale's character) is somehow responsible for Elsa's trapping in her urn, a woman with similar powers to Elsa. They soon discover that the Snow Queen is Elsa's aunt, Ingrid, who was forgotten from Arendelle when Elsa's mother, Gerda, used the power of the troll king to erase everyones memory of her, not wishing for the world to remember how Ingrid accidentally killed their third sister, Helga. Ingrid soon discovered a prophecy that stated she would one day have the love of her sisters again. With Ingrid's sisters dead however, she believed she would be forced to create new sisters. For this, she chose Emma and Elsa. Ingrid had stalked Emma her entire life in preparation for the prophecy to become true, and manipulated events in Arendelle to bring Elsa to her. Being convinced that she could only gain their love when she was the only one left, she obtained a mirror capable of bringing out the worst in people (the mirror coming directly from The Snow Queen fairy tale). If a piece of the mirror were to get in someones eye, they would see nothing but hatred in the world. Ingrid had planned to use this on everyone in Storybrooke (dubbed the Spell of Shattered Sight), forcing all of its citizens to kill each other while she, Emma, and Elsa remained immune. Ingrid had also used this to her advantage on Anna, forcing Anna to trap Elsa in the urn they originally found Elsa in.
