Naria is supposed to be a kingdom mostly populated by humans. In fact, there's hardly supposed to be anything out of the ordinary around, especially the Royal palace itself. And that was why as soon as Aragon placed his foot inside of it, he confirmed his suspicions that something had gone wrong somewhere. Keeping the supernatural community at a balance was one of his main roles as the King of Erandell, and it's a shame that since the people living at Naria were all humans, they might feel the unease but won't be able to pinpoint exactly what was wrong.
