A fan's backstory for how Elsa got her ice powers - Her mother (the Queen of Arendelle) was lost in the forest one day while pregnant with Elsa, and she encounters either an ice goddess, fairy, or enchantress; possibly an old Norse elf or frost giant. In exchange for helping her out of the forest, the ice enchantress demands that Elsa be born with ice and frost powers so the Queen of Arendelle will remember her kindness???
