Frost Kingdom, Arrendel.
Princess Anna's beautiful figure was standing at the top of the castle, overlooking the city in front of her. Now that the temperature had begun to warm up, the ice and snow were melting; Arendelle was as bustling as it used to be, but there was a sense of tension and depression spreading in the palace. This was something that had never happened before.
That was because the elder princess had left.
If the princess was still in Arendelle, it wouldn't matter if there weren't any guards in the whole palace. But now that the elder princess had left, the security of the palace rested on the guards. No one thought that the elder princess would leave so suddenly. Even Princess Anna did not think that her sister would leave abruptly and disappear without a trace.
No one knew where she went!
It was even possible that she was not in this world but had traveled to another plane.
"Sister had been gone for three days!"
