Library of Lost Things

 Library of Lost Things is a turf hut where the Huldrefólk keep the lost things they have found.

History
Back in the times when humans and Huldrefólk lived closer together, Library of Lots Things was a place of meeting for the two groups. Years later, greedy people started to mine in the Huldrefólk's territory and peace between the two species ended and the place stopped to be a place of meetings of the two groups.

Obscuren took Anna, Elsa and Kristoff to Library of Lost Things when looking for Revolute, the mythical sword of Aren of Arendelle. They did not find the sword there, but they found clues where to look for it.

Before leaving, Elsa created an ice sled and a snow bear to pull it named Bjorn.

Description
Library of Lost Things is a place where the Huldrefólk keep their findings. It does not contain only books, as human libraries do.

The objects stored there include Elsa's statue from Arendelle's cuckoo clock, lots of mismatched socks, bronze vases, sapphire necklace, a pocket mirror and shields and helmets from the times of King Runeard's rule.

The walls are covered in runic inscriptions from the times when the Huldrefólk and humans lives in peace and met in the hut to share their stories. One of the inscriptions is about the myth of Aren of Arendelle.
