Capital of The Unreturned


Recommended Posts



A colossal pit was discovered a few years ago on an island far in the South of Gal Da Val.

It was called The Abyss.





The vertical hole has a diameter of around 55 meters at the surface and the Abyss is at least 3,300 meters deep.
It possesses a unique ecosystem, wherein lie ancient and extraordinary relics that defy common sense.

The government sent a lot of determined hunters in order to unveil the secrets of the Abyss, but some of them never returned.

Many have challenged the mysterious abyss, pursuing hidden treasures and artifacts of immense value.


The Abyss is divided into at least 6 known layers.
The deeper, the more dangerous it gets.

Space and time also seem to be distorted in the depths.
Hence why each of those layers has a different hunter level restriction.


The Abyss is huge, in your quest you will only get to explore a very small part of each layer, so you might not meet many other people.


Various paranormal phenomenons have been observed in the Abyss.
There is a mysterious and invisible force that applies undesirable effects on adventurers upon specific conditions.
Those symptoms and triggers vary from a layer to another.
They are called the Curse of the Abyss.

There are only 6 known layers because going to the 6th means inevitable death.





Coming Soon












Layer 1: Edge of the Abyss


Difficulty: Normal (Trainee & Novice hunters)

Depth: 0 - 50 meters

Curse: The First Warning


The first layer that surrounds the Abyss.

Mostly inhabited by harmless animals.

You might meet quite a few rookie hunters as well there.





Layer 2: Lands of Temptation


Difficulty: Hard (Intermediate hunters)

Depth: 50 - 200 meters

Curse: Strains of Ascension


The center of the Abyss here is somehow very attractive.

It is as if everything is suggesting you to go into the giant pit.

Only intermediate or higher hunters can go there.





Layer 3: The Great Fault


Difficulty: Very hard (Advanced hunters)

Depth: 200 - 2,200 meters

Curse: Cursed Injuries


This layer is so deep that it cannot be reached by telepipes.

How the lights still reach the bottom remains a mystery.

Only confirmed hunters are allowed there.





Layer 4: Garden of the Eternal Flowers


Difficulty: Ultimate (Expert)

Depth: 2,200 - 2,800 meters

Curse: Mind Devourers


This is the lowest layer from which hunters can still come back alive.

The environment is very hostile and unhealthy.

Only expert hunters are allowed to descend to this point.





Layer 5: Capital of the Unreturned


Difficulty: Ultimate (Expert+)

Depth: 2,800 - 3,200 meters

Curse: Chains of Death


The largest layer horizontally with more than 10 km².

Hunters who go there never come back from this layer.

Their only sign of life come from the very rare ascending photon capsules intercepted at the 4th layer.





Layer 6: The Final Dive


Difficulty: Ultimate (Legendary)

Depth: 3,200 - ???? meters

Curse: The Last Breathe


Only one thing is clear. If you go there, you die.

That is why it is called the Final Dive.

At least your name shall be remembered.









You will find a lot more information about the different layers and their curses in the game quest board.    

The quest is not (and won't be) exactly finished.

It will get released in an unstable version in a few days because I have to gauge realtime difficulty, average time to complete it in 4 players teams, eventual issues etc.
So please report any bugs you find in the quest.

I planned to make it a very long quest, telling the story of the Abyss, but I know many people don’t like long quests (in addition to the frustration of getting a late disconnection) so I made it much shorter than originally intended.
Thus it should take less than an hour to finish it.

Capital of The Unreturned is abbreviated CTU (Pronounced as "City U").

As you can guess, this is a tribute quest to Made In Abyss.

But no worries, there is no manga spoiler in the quest.

The quest storyline and stuff are mostly made up.

Stay tuned for the incoming season 2 in 2022 though.

The Abyss has opened its doors!


Quest is live


After more than 75 hours of testing ingame and my whole weekend on it, it's finally here!
Remember it is not in its final version though. Some things are unfinished.
Please report any issue you find in the quest.

The poison is not over powered.

You probably did not understand the Curse of this layer.

The Abyss Guide in quest board is a lot of reading but has some useful information in it.

The quest is pretty sick. There are a lot of hidden surprises especially if you're not ready for it.


The first run I did was without reading the Abyss Guide, a bunch of things didn't make sense and I was trying to figure out what was happening from experience. Often times it was too late by the time I realized. 


Second run I read part of the guide for each layer, and it made much more sense. It's the type of quest that will surprise you the first few times, but after that, once you figure it out, it's not that bad to get through.


The hidden secrets add a ton of depth to this quest. I didn't have a chance to dig deeper, but it seems each layer is hiding something or somethings, and there are multiple endings. 


All in all a really fun quest which adds a breath of fresh air to episode 4...and it's fantastic for grinding great numbers of enemies.
