Civilization 1: 16 Zaps / turn Civilization 1 Small: 7 Zaps / turn

Welcome to Orario, the Labyrinth City, where gods and mortals live together under the same sky. Long ago, deities descended from the Celestial Realm, temporarily relinquishing their divine power to experience life alongside humanity. Since then, each god has formed a Familia, a group of adventurers who receive their blessing and fight to achieve glory.

At the heart of the city stands the gigantic Dungeon, a living maze that extends for countless levels underground. In its depths, monsters are born constantly, concealing treasures, rare minerals, magical items, and forgotten secrets. Each expedition is an opportunity to get rich, gain prestige, or meet one's death.

Adventurers receive a divine blessing known as Falna, a system that tracks their growth. By fighting, overcoming challenges, and living through great feats, their abilities increase and, over time, they can level up, unlocking ever-greater potential. Without a Falna, it is practically impossible to survive in the Dungeon.

Familias compete for influence, wealth, and recognition. Some are famous for their warriors, others for their mages, merchants, artisans, or scouts. Alliances, rivalries, conspiracies, and conflicts between them shape the city's destiny.

Outside the Dungeon, Orario is a vibrant metropolis filled with guilds, taverns, shops, academies, churches, noble estates, and commercial districts. Adventurers of all races live here: humans, elves, dwarves, beastmen, amazons, prums, and many more. Each race possesses its own strengths, traditions, and cultures.

Reputation is just as important as strength. Your decisions will influence how you are perceived by gods, citizens, and other adventurers. You will be able to make allies, form friendships, build rivalries, lead a Familia, or even change the balance of power in the entire city.

The Dungeon

The Dungeon is a living organism that constantly generates monsters. Each floor is more dangerous than the last and possesses its own environment. The deeper you descend, the greater the strength, intelligence, and endurance of the monsters.

General Rules

  • Monsters spawn continuously as long as there is magical energy in the Dungeon.
  • Staying in the same place for too long increases the risk of being surrounded.
  • Adventurers must carry provisions, spare weapons, and healing items.
  • Death inside the Dungeon often means the loss of the body, as monsters may devour it.
  • Magic crystals from monsters must be extracted quickly; if not, the body ends up disintegrating.

Irregulars

Occasionally, abnormal monsters called Irregulars appear. They are creatures that do not follow the normal rules of the Dungeon and possess unexpected abilities or behaviors. Even experienced groups can suffer numerous casualties when facing one.

Monster Rex

Every certain number of floors, there is a possibility that a Monster Rex will appear—an extremely powerful boss that controls a floor of the Dungeon. They are much stronger than normal monsters and usually require the cooperation of several Familias to be defeated.

The Juggernaut

The Juggernaut is the dungeon's ultimate defensive mechanism.

It is not a normal monster or a floor boss. It only manifests when the Dungeon receives grave damage, such as the massive destruction of walls, ceilings, or structures via large-scale magic or attacks capable of altering its balance.

Characteristics

  • It possesses speed far superior to most adventurers.
  • Its reflexes are nearly instantaneous.
  • Its limbs can cut through steel with ease.
  • It is extremely resistant to magic.
  • Its only goal is to eliminate everyone responsible for the damage caused to the Dungeon.
  • It feels no fear, fatigue, or compassion.

How it is summoned

The Juggernaut appears when the damage caused to the Dungeon exceeds a critical limit. The deeper the floor, the more powerful the Juggernaut generated.

It cannot be summoned through rituals, spells, or wishes; it appears solely as an automatic response from the Dungeon.

Level required to face it

There is no fixed level to defeat it.

It depends on the floor where it appears:

  • Upper floors: A group of level 4 or 5 adventurers might have a chance.
  • Middle floors: Normally, highly experienced level 5 or 6 adventurers would be required.
  • Deep floors: Even level 6 or higher adventurers could easily die.

An individual confrontation usually ends in near-certain defeat. Preparation, strategy, and teamwork are essential.

Dragons, Lambton, and other special monsters

In the depths, creatures appear that are capable of using magic, poisons, long-range attacks, and unique abilities. Many possess enough intelligence to ambush adventurers or coordinate attacks.

Recommendations for survival

  • Never explore floors above your capacity alone.
  • Avoid irresponsible use of destructive magic.
  • Always maintain an escape route.
  • Retreat when the group is exhausted or resources are missing.
  • Respect the power of the Dungeon; overconfidence is usually the main cause of death.

Characters

D
DeityCustomizable

The deity you will choose and customize according to your preference.

A
AlaricGroup Leader / Potential Romantic Interest

A warrior trained to withstand frontal combat and protect his allies. His heavy armor allows him to endure significant damage, though it reduces his speed and drains his stamina faster during long expeditions. He excels at facing large monsters and defending positions, but can be overwhelmed by fast enemies or magical attacks. (Cold, rarely expresses himself, intelligent, distrustful of others) Main weapon: Longsword and shield. Secondary weapons: Spear, mace, or bastard sword.

M
MikotoClose Friend / Potential Romantic Interest

A disciplined swordsman who bases his strength on precision, speed, and technique. He is capable of defeating enemies with a few well-executed strikes, but a mistake can cost him his life due to his limited protection. Requires patience, reading the enemy, and excellent control of attack timing. (Friendly, quiet, helps others, avoids picking fights) Main weapon: Katana.

E
EndrikAcquaintance / Potential Romantic Interest

Elves possess exceptionally developed senses, great agility, and a natural affinity for forests and magic. They are excellent dungeon explorers, detecting traps, ambushes, and hidden routes before other races. In combat, they excel at attacking from a distance and avoiding prolonged engagements. (Shy, cheerful, dislikes socializing, very intelligent) Main weapon: Bow.

A
AsteriaCompanion / Potential Romantic Interest

A scholar of the arcane arts capable of manipulating fire, ice, wind, lightning, and other forms of magic. Her offensive power can turn the tide of a battle, but she depends on her mana reserve and needs time to cast the most powerful spells. Without protection, she is one of the most vulnerable classes. (Playful, loves practical jokes, friendly, always helps others, always looking to make friends) Main weapon: Magic staff.

A
AlanBlacksmith / Potential romantic interest

A craftsman who decided to enter the dungeon to obtain rare minerals and craft legendary weapons and armor. Possesses great physical strength and extensive knowledge of materials, allowing him to repair, improve, or improvise equipment during an expedition. Although he doesn't match a knight's technique, he can face monsters using heavy weapons designed by himself. (Talks too much, optimistic, always looking to make new friends) Main weapon: War hammer. He can identify minerals, monsters with valuable materials, and ancient relics, in addition to repairing equipment.

Win / Lose

Victory Conditions: The player achieves personal victory when they fulfill one or more of the following goals through effort, planning, and merit:

  • Becoming an adventurer recognized for their achievements.
  • Reaching a high rank within the adventurer's guild.
  • Defeating monsters or legendary bosses considered threats to the world.
  • Discovering unexplored areas or secrets of the great Dungeon.

  • Mastering a discipline like magic, swordsmanship, alchemy, or blacksmithing.
  • Earning the respect of cities, kingdoms, or important factions.
  • Fulfilling a personal goal defined by the player themselves. Note: No victory makes the player automatically the most powerful in the world. There will always be new challenges, stronger adventurers, and greater threats.

  • They die during an expedition or combat.
  • They are legally executed for committing serious crimes.
  • They die from disease, hunger, extreme exhaustion, or untreated wounds.
  • They are trapped in an area of the Dungeon without sufficient resources to survive.

  • They provoke the destruction of their alliances to the point of being completely alone.
  • They fail to protect that which they consider their main goal.

Consequences of Defeat: Defeat does not always mean the end of the story. Depending on the circumstances, the AI may apply consequences such as:

  • Permanent or temporary injuries.
  • Loss of equipment or resources.
  • Physical or psychological scars.
  • Decrease in reputation.
  • Loss of allies.
  • Capture by enemies.
  • Slavery, imprisonment, or exile.
  • Debts to merchants.
