Ah, so that was it. The sciences were the rise, even in Arendelle, though her small kingdom was distant to the rest of the world. Elsa was only aware to a limited extent of the existence of the sciences. The idea of them opposing magic didn't really make sense to her, not exactly. "I imagine my powers obey certain laws and principles, though I am usually blind to them. I focus my will, and I can conjure certain effects, but there are limits and I must have a care or lose control."

The request, though, made her shake her head. "I tried when someone mentioned that you could not leave, before I came here. I had to be sure. If you walk along the roads, at a certain point, you will find yourself walking towards the city all over again. I do not know any way to leave." But, if he was a man of science, maybe he would prefer to see it for himself. "I can show you, if you wish."
