The Capital of the Unreturned (還 (かえ) らずの都 (みやこ) , Kaerazu no Miyako), referred to as "Shourou" Layer (ショウロウ層 (そう) , Shōrō-sō) by Gaburoon and translating to "The Capital of the Unreturned" in the language of the Abyss Tribe that Ganja had encountered, is the sixth layer of The Abyss.

It is the point of no return, the Absolute Boundary (絶界 (ぜっかい) , Zekkai), since it is physically impossible to survive the ascent from here, at least in human form, hence the name. When a White Whistle Delver descends down to the 6^th Layer, it is called "The Last Dive" (絶界行 (ラストダイブ) , "The Last Dive", Crossing of the Absolute Boundary^?), as none of them ever see the surface again.

Description

In the Capital of the Unreturned, the ruins of a majestic city sleep undisturbed. A rumor in Orth exists about a Golden City sleeping at the bottom of The Abyss, which supposedly originated from this very city within the 6^th Layer. The city itself is described as golden—however, the ruins are covered by a crystalline material. It is unclear whether the buildings were intentionally made out of this crystal or if they became fossilized over time. The ruins themselves spread out in every direction, and oftentimes buildings are diagonal, upside down, or sideways. Creatures of Absurd to Extraordinary danger level become quite common, as are random, bright geo-thermal explosions that emit poisonous gas. Bird repellent used on the Mail Balloons does not work on the aviary species in the 6^th Layer.

Here, the Curse inflicts inconceivable pain and leads the victim to mutate and devolve into a mindless pile of flesh, their intelligence and consciousness vanish, leaving them with only basic instincts. It is also possible that the curse could result in death, which, all things considered, is perhaps the more merciful outcome. However, under certain circumstances humans may mutate into Narehate with their mind intact.

It is here that The Village of Iruburu came into existence, with the Three Sages in charge of it.

Beyond the village are steep landscapes, more ruins, fields of Eternal Fortunes, and the habitat of the Emperorshell, which exceeds the depth of 14,000 meters, accompanied by flaming iron rain.

Located in an isolated section approximately 300 meters before the beginning of the 7^th Layer is an outpost used by Hail Hex, the Delver group lead by the White Whistle Delver Srajo.

A landmark which Srajo calls "The Eye" exists near the threshold of the 6^th Layer and 7^th Layer.

Trivia

• Because the 6^th Layer is isolated from the 5^th Layer and above, it's said to contain many creatures that have yet to be recorded.
• According to the author, the buildings in the 6^th Layer are from different eras and are mixed together.
• The word "shourou" means "bell tower", in Japanese.
• Nether Glyphs written on the old map of The Abyss read "やらずあめのとし" meaning "city of rain that starts to fall as though trying to prevent a guest from leaving".
