Agdar and Idunn worked in their family's castle in Arendelle, as a king and queen. One morning, they had to be escorted into town via carriage, on a royal errand. While they were walking along Arendelle's main street, they saw Death. Death beckoned to them.
Agdar had them both driven back to the castle as fast as he could, and told his butler Kai what had happened. "I'm going to take Idunn with me on the ship," he told him. "I'll go to the sea. He'll never find us there."
Kai saw them both off at the docks. After they left, he went into town looking for Death. When he found him, he asked, "Why did you frighten my king and queen that way? They are only in their thirties. They are too young to die."
"I am sorry about that," replied Death. "I did not mean to beckon to them. But I was surprised to run into them here. You see, I have an appointment with them this evening...out in the ocean."
