The 3rd layer is a 4000m vertical drop down a circular shaft that is home to large aerial predators, such as Madokajacks. The vertical drop is significantly smaller in diameter than the other levels of the Abyss, as evidenced by the Abyss Map.
While the inner caverns mainly house non-aggressive creatures, occasionally Madokajacks will nest in the larger caves.
Crimson Splitjaws have also been known to use their brute strength to infiltrate the side caves in order to capture their prey. Amakagame are also located in the cave systems and can pose a threat to Delvers. However, their main source of sustenance are Neritantans and they do not actively hunt humans.
An ancient 'pirate ship' was seen partially exposed in the side of the Great Fault.
- In the manga, the Amakagame is only seen as a footnote in the form of a sketch in a map detailing the progress of the group.
