The Final Maelstrom (最果 (さいは) ての渦 (うず) , Saihate no Uzu) is the seventh layer (深界 (しんかい) 七 (なな) 層 (そう) , Shinkai Nana-sō) and the last known layer of The Abyss.

According to Srajo, there has only been one instance of the 7^th Layer's Curse being documented. It was found in a sealed letter in the 1^st Layer, 250 years ago. As such, the true nature of the Curse of the 7^th Layer is unknown.

Lyza's notes state that she spotted a figure resembling Reg at the entrance to this layer. She recorded it as a "Human-like Silhouette", later known as "Girl-type".

Description

Secrets transmitted from the Last Dives of generations of White Whistle Delvers are passed down, via word of mouth, to none but themselves. Rumors of a mysterious ring, "Ring of the Essence", which only a few White Whistles are said to have seen, and claims that mysterious beings, referred to as "Gatekeepers", exist along the path to the bottom of The Abyss.

A landmark which Srajo refers to as an "Eye" exists near the threshold of the 6^th Layer and the 7^th Layer.

Faputa was able to communicate with the soul which inhabits Lyza's whistle, Doni, and confirm the existence of the "Ring of the Essence" and an unknown being related to Reg, in this layer.

Currents of some unknown, extremely cold gaseous substance, which causes objects to frost, runs along the bands of The Force Field. The climate is also quite rainy, adding to the seeming lush vegetation of the layer. The landscape appears jumbled and disjointed, with many cliffs, land-bridges, and caves.

In this layer exists a phenomenon known as Katchaba (渦中厄場 (カッチャバ) , Katchaba, Maelstrom Danger Zone^?), where the senses of an individual are negated.
