Locke & Key, Volumen 4: Las Llaves del Reino

Locke & Key has such a rich mix of genres, and I wonder what inspired the choices behind blending these elements so seamlessly.

The emotional stakes felt higher than before, especially with the secrets coming to light. How did others interpret the character dynamics?

The imaginative keys are such a core part of the series. I'm curious whether Hill had specific influences or if they evolved during writing.
