El caballero fantasma

The ghost knight feels so vivid and unique—I'm curious whether the author envisioned this character from the start or developed them during writing.

It made the adventure feel fun and accessible for younger readers, but I wonder if some might find the ghosts a bit too eerie or funny.

The world-building made the magical locations feel alive and welcoming at the same time—was that a deliberate choice to ease young readers into the fantasy?
