There are so many nooks and crannies for Iceland’s hidden people to live. This is an Icelandic moss field and you can’t help but look for the Huldufolk here.
This story of how the Huldufolk (hidden people) came to be finds Adam and Eve at home in their beautiful garden. One day, God comes to visit and asks to meet all the couple’s children. However, Eve had only finished bathing a few of her children, and was embarrassed to show her Creator the dirty ones. So she introduced the clean children and hid the others.
“Are there any children I haven’t met yet?” God asked. Eve said no.
Of course, being omniscient, God knew that he was being tricked and declared, “Those who you hide from me shall also be hidden from men.”
And so, the hidden children became invisible, taking to the hills and moors and rocks. It is from these children that the Hidden People are descended, while humankind is descended from the children whom Eve showed to God. Hidden People can only be seen by human eyes if they want to be.
