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. The Tower is enormous beyond belief and basically divided into three parts: Inner Tower, Middle Area and Outer Tower; there is also the Outside of the tower. Each of the parts of the tower are then divided into Floors there are at least 135 floors and the 134th is the topmost explored floor and is known as the 'Top', despite there being higher floors still. Each floor is a vast enclosed space - with the floor said to be as large as a continent, one example of this is the ocean contained in the 20th floor's Inner Tower; while the sky is actually a construction of Shinsoo rather than the sky we know.

Notes:
 * There are at least 135 floors; each has a Guardian (except the 43rd Floor)
 * Each floor is divided into Inner Tower, Middle Area and Outer Tower; each has a Ruler (who requires a Guardian present) who are High Rankers
 * Guardians control Shinsoo, provide contracts for Shinsoo use, create special tests for Irregulars and teleport Regulars/Irregulars (either to the next floor if they passed or to an appropriate exit if they do not)
 * Shinsoo use throughout the Tower is common, but requires the individual has a contract with a guardian (or their item has a contract with a guardian).
 * The entire Tower is populated by creatures also known as Shinheuh (God Sea Aquatic Animals); because Shinsoo is characterised as water and Shinsoo fills everything – everywhere in the tower is in the 'sea of Shinsoo,' so, every species of creature within the Tower is a Shinheuh.



Inner Tower
Inner Tower is where selected Regulars climb the Tower. The Ruler of each floor decides on a series of tests, the specifics of which are decided by the Test Director and then administered by Test Administrators and other staff. 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; without a Guardian, teleportation doesn't work so everyone must take the staircase in the Middle Area to reach the next Floor.

The 'Top' of the Tower
There are currently 134 explored floors, the 134th floor is where Zahard reigns from and is known as the 'Top' of the tower, however there are floors above that, but no one has gotten through the 135th floor or further yet, because Guardians are very hostile.

Anyone who reaches here becomes a Ranker; here, everything that could be wanted is gathered; all the riches and glory and power that one could imagine. It is strongly believed that the day Zahard begins to go on the move again, is when the Zahard Empire will expand by another floor; that this is but a rest stop on his journey.

While at the very top of the tower including the unexplored floors, it is said that one can see the stars - though many inhabitants of the tower believe this to be a fairy tail.

Middle Area
The area is smaller than the Other Towers, and it varies by the floor - the Middle Area is an area between the Inner and Outer sections; there is also a stairway in the Middle Area which can be used by Guides and 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 - if he could teleport, both 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. Travel within the Middle Area can be dangerous at times, depending on the floor (such as the Floor of Tests) - as numerous dangerous Shinheuh (God Sea Aquatic Animals) such as the White Steel Eel inhabit some parts.

Both Regulars and Rankers can live in this area, however while Regulars can access the Middle area from Floor 3 after giving up, they only earn the right to live there themselves (or with their family members) once they reach Floor 20 - but this means that people who are not Regulars can live there too which is attractive as the standard of living is 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.

Outer Tower
Outer Tower is the residential district and each floor of the Outer Tower is as large as the continent of America on Earth. Also, some or all of the Floors have the practice of issuing a Residential Card to the dwellers to identify them. Sometimes, those among them who show the potential to climb the Tower get chosen and become Regulars, earning the right of climbing the Inner Tower. This is important as they are not otherwise able to move between the floors - there is no means to travel directly between floors in the outer tower and access to the middle area is controlled.

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.

Outside of The Tower
Little is known about what's outside of the tower.

Few things are certain as of now; Teleporting also seems to function outside of the Tower although it's unknown if this function is bound 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).

All irregulars of the past have been from the outside and at least some regulars are also chosen from the outside. This is supported by the fact Rachel has read about The Tower in books (likely written by failed regulars) and called Headon a "fae" who grant children's wishes.
