Anna: After having said goodbye to Elsa and Kristoff in Arendelle, Anna's carriage entered a new realm, passing through a portal into the Morphling Country, a world of strangeness. This was the realm of characters such as the Mad Hatter (who had left for Wonderland), Belle (who had moved to the World of Magic), and most importantly, Janus, the God of Choices.
Anna asked a commoner, "Do you know where Janus is?"
The commoner pointed at the Temple of Janus.
