Underworld

The Underworld (アンダーワールド) is the mysterious virtual world in which the Alicization Arc takes place.

Axiom Church
The Axiom Church was founded around 30HWC (100 years after the creation of Underworld). At the time, the founder and head of the church was a girl named Quinella. Her Sacred Task was one not seen before in Underworld: “Sacred Arts Research.” She soon became very proficient at the Sacred Arts and had discovered many new rituals that people could use in every day life. At the age of thirteen, Quinella decided she didn't want to rule over the people as a lord or baron - she wanted to have absolute control, she wanted to become God. To do this, Quinella started doing “miracles” in front of people, predicting storms and healing sick and injured people in the name of "god". She told the people that a shrine to worship god needed to be built in order to perform even greater miracles, hence a large marble spire was erected in the center of town. This was the beginning of the Axiom Church. Years later when Quinella felt her life was coming to an end, she desperately tried to find a form of Sacred Arts that could manipulate her Life. Even at the verge of death, she still tried chanting various combinations of verses in the hopes of finding something that could help her. One fateful night, when she was just on the brink of death, Quinella discovered the Sacred Art: “Inspect Entire Command list,” and at the bottom of this list was the command that Quinella had been searching for, the one that would let her truly become God.

Human World
The Human World is where the Humans live in the Underworld, it's a perfect circle with a diameter that measures around 1500 kilometers.

The Human World is divided into four empires: Norlangarth North Empire, Eastabarieth Empire, Wesdarath Empire, and Southacroith Empire. The capital of all four empires is Centoria, from where it is ruled by the Axiom Church and the four empires.

Norlangarth North Empire


Norlangarth North Empire (ノーランガルス北帝国) is the northern empire of the Human World. Rulid Village is the northernmost village in this empire. Zakkaria is a town to the south of Rulid Village. Deusolbert Synthesis Seven used to be the Integrity Knight overseeing the Norlangarth Empire.

Eastabarieth Empire
Eastabarieth Empire (イスタバリエス帝国) is the eastern empire of the Human World.

Wesdarath Empire
Wesdarath Empire (ウェスダラス帝国) is the western empire of the Human World.

Southacroith Empire
Southacroith Empire (サザークロイス帝国) is the southern empire of the Human World.

Edge of Human World
Edge of Human World (人界世界の果て) is the border between the Human World and the Dark Territory.

Mountain range at the Edge
The Mountain range at the Edge (果ての山脈) is the mountain range that surrounds the Human World.

Dark Territory
Dark Territory (ダークテリトリー) is the country of demons. It houses goblins, orcs, etc. It is situated at the other end of the Mountain Range at the Edge.

Law System
The Human World is ruled under the Axiom Church who established the Taboo Index as a supreme law above all, and its objective is to ensue the pacifical live of people and the self-reliance of the live within the human world. The fundamental statement of the Taboo Index is that one cannot lower the «Life» of anyone without a reason.

Below the Taboo Index are the laws established in each one of the four empires, and below it are the rules that apply to certain places such as the Sword Mastery Academy.

Although this system rules the entire world, and has a good purpose, it is full of flaws that people had found to commit evil acts without breaking the law.

It was later revealed that it was actually created by Quinella when she created the Axiom Church to ensure that nobody would be able to find the secret to "level up" as she was doing, allowing her to gain control over the Underworld human residents.
