The books focus on the functionality and purpose of Chute E7, which is:
* A high-speed escape pod for the fairy world's elite: It's used for quick and discreet travel between the fairy world and the human world.
* Hidden within the fairy world's main entrance: It's concealed from human eyes within a hidden area of the fairy world's portal.
* Equipped with advanced technology: It's likely equipped with advanced technology, such as anti-gravity propulsion and cloaking devices, allowing for fast and secure travel.
There are no descriptions of its shape, color, or specific features. This is likely because its appearance isn't relevant to the story, and the author focuses on its function and importance.
If you're looking for a visual representation, you might need to rely on your own imagination or create your own interpretation based on its purpose and functionality.
