It is a humid jungle of strong vines, weaving giant concave discs called Flat-creepers. The tops of the discs capture water from the air and the light from the forcefield refracts from this water, giving the scenery a blue hue. The landscape is constantly changing, and as such, no attempts have been made at creating a detailed map of its features, beyond pointing out non-jungle landmarks.
The high concentrations of water in this region causes high humidity and sometimes fog.
In the middle region at the 9,000 meters mark, there is the famous Garden of the Flowers of Resilience, an area filled with Eternal Fortunes, the trademark flower of the Abyss. The distinctive sight produced by the countless glowing flowers make the garden one of the most beautiful landscapes of the Abyss.

Points of Interest
- In chapter 7, pages 15–16, Shiggy, while talking about the different layers, says, "Anyway, we're finally on to the fourth layer! Only Black Whistles and above can go here. [emphasis in original]" and "The fifth layer! This is the domain of White Whistles alone[.]"
This is contradicted in the second volume's chart which says the depth limit of Moon Whistles is the fourth layer and that the limit of Black Whistles is the fifth.
The original Japanese releases were investigated and there is no translation error.
However, in chapter 23, page 7, Bondrewd states in a conversation with another Delver, "Why bring this up now? It's also for this very purpose that I proposed Black Whistles enter the fifth Layer[.]"
This suggests a change in the depth limit has occurred at one point and as such, it is possible that Shiggy isn't aware of it.
