Structure of the Tower

''"Tower of God" redirects here. For the series as a whole, see Tower of God (series) ''

The Tower is the world and setting of Tower of God. There are currently 135 confirmed floors, and at the top, everything that could be wanted is up there. The 135th floor is yet to be conquered. The Tower is basically divided into 3 parts: Inner Tower, Outer Tower, and Middle Area.



Inner Tower
Inner Tower is where the selected Regulars climb the Tower. The Ruler of each floor decides on a series of tests, specifics of which are decided by the Test Director and then administered by Test Administrators and other staff.

And as a Regular, they are entitled to rights.

The Regulars must pass all of the tests to go to the next floor. They are then teleported to the next Floor. The only exception is the Forty-Third Floor where there is no Guardian because Enryu killed it. And without a Guardian, teleportation doesn't work and a Ruler can't rule. So, everyone has to take the staircase in the Middle Area to reach the next Floor.

Regulars must take the exams to reach the next floor until the 20th Floor, and they can go in and out of the Middle Area after the 20th floor. If they wish to, they can settle in the Middle Area.

Regulars who give up in the middle of climbing the Inner Tower, after they've reached the 3rd Floor, are stripped of their rights and are sent to the Middle Area. This is likely so they can return home as it can be used to travel between the Inner and Outer Tower. However, Regulars who were chosen from outside the Tower are likely teleported back home by Headon or the Guardian of the floor or via some mechanism in the Tower.

Anyone who reaches the 134th floor becomes a Ranker.

Note: The Ruler has the right to decide the exam of his floor. But if the Guardian raises objections, he must follow the Guardian's wish.

Outer Tower
Outer Tower is the residental district and each floor of the Outer Tower is as large as the continent of America on Earth. Lero-ro apparently called it the Residential Tower in Ch 10. And apparently, people are born in the Outer Tower and live on the same Floor for their entire lives. But it's unknown what happened to the residents of Floor 43 after Enryu killed the Guardian of that floor, though it's possible all of them had to evacuate the Floor.

Also, some or all of the Floors have the practise of issuing a Residential Card to the dwellers(Source: Backryun's profile). This is possibly to keep track of certain details like a resident's birth and death records, family registrar, marriage registrar, employment records, eligible benefits and so on.

Once a person shows potential of climbing the Tower, he or she get chosen and becomes a Regular, earning the right of climbing the Inner Tower. The cultures of each floor are all different, and the climates and temperatures all vary. These conditions have been decided by the tendencies of the Guardians and the Rulers of each floor.

Each area of the Inner Tower, Outer Tower and Middle Area are managed by the Ruler (the title is different for each floor. They are called President, Chief, etc.) of the area. The Rulers are all High Rankers and are all followers of the family which owns the floor.

Middle Area
The Middle Area is an area between the Inner and Outer sections. Both Regulars and Rankers can live there. However, Regulars only earn the right of living there by themselves or with their family members once they reach Floor 20. This means that people who are not Regulars can live there too.

The Middle Area can be used to travel between the Inner and Outer Tower.

The stairways in the Middle Area are used by Rankers to skip floors of the Inner Tower as it's very likely only Guardians can teleport others. (This is evident from the fact Evan Edrok, a Guide, accompanied Yuri Zahard to assist her in navigating the maze-like paths of the Middle Area. Yet if he could teleport, both of them would've simply appeared on the First Floor, during Chapter 1 instead of climbing down the stairs.) It's also likely one can only navigate the stairways of the Middle Area with the assistance of a Guide as there are likely dead ends.

The area is smaller than the Other Tower, and it varies by the floor. There is some interchange with the Outer Tower. The standard of living is much better.

It is also very likely only the staff members of Floor 2 to Floor 19 live in the Middle Area or if not, in their own quarters within the Inner Tower.

The Top
The current known top of the Tower is the 134th floor.

There are floors above that, but Zahard was unable to go through Floor 135(and likely complete the Tests) because the Guardian was very hostile. The same can be assumed for the Guardians located on 136th Floor and beyond. And it's very likely the fact that Zahard was able to obtain contracts with the Guardians from Floor 1 to 134(except for Floor 43) held no weight with these Guardians.

It is said that the one who reaches the top will be able to see the stars, due to the fact that most of the skies in The Tower are artificial constructs made of Shinsoo.

It is strongly believed that the day Zahard is on the move again, is when The Zahard Empire will expand by another floor.

Outside of The Tower
Little is known about what's outside of the tower. All irregulars of the past have been from the outside.

Some regulars are also chosen from the outside. This is supported by the fact Rachel has read about The Tower in a book and called Headon a "fae" who helped "the children wishing to ascend the Tower" Ch 76.

A few things are certain as of now. Teleporting also seems to function outside of the Tower although it's unknown if this function is binded by the same rules restricting teleporting within the Tower.

Also, shinsoo likely doesn't exist here and instead, people breath through air(oxygen, water and other substances).

It is possible the concept of "unchosen" and "chosen"(chosen regulars, unchosen irregulars, informal Princesses who've been chosen once, formal Princesses who've chosen again, Koon Eduan's chosen children, etc.) originates from outside the Tower. And Rachel has told Baam stories while he was in the cave about "the world of light, filled with joy", "the fruits borne by the tree given by God", "the yearly festivals", "a place where the chosen children play". And supposedly, the "world" above the cave is a place "where only those who have been chosen can play" Ch 73.

It is unknown how one becomes chosen in the world outside of the Tower.
