Yule bell

The Yule Bell is a bell that the royal family of Arendelle rings to mark the beginning of the winter holidays. After the Gates were closed, the bell hasn't been rang since the reconnected Elsa and Anna reopened the gates and brought the tradition back.

History

Before the kingdom of Arendelle and its people could start to celebrate Christmas, the kingdom's king and his family ring a silver bell to mark the beginning of it. Once it was ranged the royal would bid their farewell as they leave to take part in their Christmas traditions.
