What are the Gates and dungeons in Solo Leveling, and how much of where they came from is ever explained?Fiction

In-universe lore. Claims are judged against the fiction's own canon, not the real world.

Solo Leveling opens on a world that has lived with the Gates for about a decade: blue portals that lead into dungeons full of monsters, and an entire industry of licensed hunters who raid them for a living. The story only later says who put them there.

  • Hunters exist because of the Gates: the mana that flowed into the human world through them integrated into certain people's bodies and granted them magical abilities.▰▰▰▱▱ likely3 points

  • Gates are described as portals that bridge the human world and the realms called dungeons, with the dungeons themselves called pockets of the chaos world, and a gate remains open until the dungeon boss inside is defeated.▰▰▰▱▱ likely4 points

  • The dungeon economy runs on two kinds of loot. Essence stones, found inside the corpses of magic beasts, are described as the primary source of income for hunters, while mana crystals found inside dungeons are a secondary one, and because electricity does not work inside dungeons the crystals have to be mined with manual methods such as pickaxes.▰▰▰▱▱ likely4 points

    • Essence Stones are small glowing stones that are found inside the corpses of magic beasts. They are generally very valuable and serve as the primary source of income for hunters around the world.Essence Stones - Solo Leveling Wiki analysis
    • Mana Crystals are a blue-colored, magical mineral found inside dungeons. Although they aren't worth as much as essence stones due to not containing as much mana, they can still sell at high prices and serve as a secondary source of income for hunters around the world.Mana Crystals - Solo Leveling Wiki analysis
    • As electricity doesn't work inside dungeons, hunters are required to mine mana crystals with manual methods, such as pickaxes.Mana Crystals - Solo Leveling Wiki analysis
    • The ramifications of an economy driven by monsters, raids, and mana crystals are explored in subplots about rival guilds fight over the rights to raid portals, where they can not only mine crystals (which results in profits) but also to train new hunters.Solo Leveling Season 1 Review - IGN analysis
  • The double dungeon was a hidden dungeon that appeared inside two separate D-Rank dungeons, and unlike most other dungeons it contained no monsters but a series of gigantic statues. It served as a base of operations for the Architect, and was used by Ashborn to find a human worthy of inheriting his powers as the Shadow Monarch.▰▰▰▱▱ likely3 points

  • The Gates started appearing in the human world around 10 years before the start of the story, and the reason given is that the Rulers created them to saturate the human world with mana so that it could withstand their war against the Monarchs.▰▰▱▱▱ likely2 points
    Supports
    • They started to appear in the human world around 10 years prior to the start of the story, as a result of an intent of the Rulers to saturate the human world with Mana in order for it to withstand their war against the Monarchs.Gates - Solo Leveling Wiki analysis
    • As later discovered by Sung Jinwoo, the Rulers were the ones who created the gates for the sole purpose of filling the human world with mana. This would reinforce the earth for their coming war with the Monarchs and ensure that humanity wouldn't be completely wiped out by the time the bloodshed was over.Mana - Solo Leveling Wiki analysis
  • A dungeon that is not cleared in time undergoes a dungeon break, in which the monsters inside cross over into the human world and attack the civilian population, and beasts out of a high-rank dungeon can destroy cities or even countries if left unchecked.▰▰▱▱▱ likely2 points
    Supports
    • It should be noted that in order to prevent the loss of human life as much as possible, a Dungeon must be cleared within seven days. If it is not, then it will undergo what's called a "Dungeon Break", meaning that the monsters inside the Dungeon will be able to cross over to the human world and attack the civilian population.Dungeons - Solo Leveling Wiki analysis
    • If a dungeon isn’t cleared in time, a Dungeon Break occurs, allowing the Magic Beasts inside to escape into the human world. In the case of high-rank Dungeons, these Magic Beasts can destroy cities or even countries if left unchecked.Magic Beasts - Solo Leveling Wiki analysis
  • A gate's rank is a reading of the magical energy it emits, calculated with magic sensors on the same S to E scale used for hunters and magic beasts, and the strength of the monsters inside usually correlates with the dungeon's rank.▰▰▱▱▱ likely3 points
    Supports
    • Much like how it is with Hunters and Magic Beasts, the threat level of a gate is categorized by the standard S-E ranking system which is calculated with magic sensors. As a result, E-Rank gates are considered very low-risk, while S-Rank gates put entire countries in a state of emergency.Gates - Solo Leveling Wiki analysis
    • Although what really determines the rank of a Gate is the quantity and quality of magical energy that it emits from within and is measured, Gates also tend to be larger when they rank higher, as D-Rank gates are about the size of large doors while S-Rank gates are so large that they appear to be like hurricanes.Gates - Solo Leveling Wiki analysis
    • They can be classified into the S-E Ranking System and the strength of the monsters usually correlates with the Dungeon's rank.Dungeons - Solo Leveling Wiki analysis
  • A red gate seals its entrance once someone walks through it and will not open again until the boss is defeated, the entire raid party is killed, or a dungeon break occurs. The lowest difficulty it can present is B-Rank, and one day inside a red gate equals one hour back in the human world.▰▰▱▱▱ likely3 points
    Supports
    • Aside from its red color, a Red Gate differs from a normal gate in that it seals off its entrance once someone walks through it, trapping the hunters already inside the gate and preventing anyone else from the outside from entering the gate. After this happens, the gate will not open until one of three things happen: the boss is defeated, the entire raid party is killed, or a dungeon break occurs.Red Gate - Solo Leveling Wiki analysis
    • Adding to the danger, the lowest difficulty level a Red Gate can present is B-Rank, placing the trapped hunters in a dire situation unless they have the support of at least one A-Rank hunter among them.Red Gate - Solo Leveling Wiki analysis
    • Time is also dilated inside Red Gates, to the point that one day inside a Red Gate equals one hour back in the human world.Red Gate - Solo Leveling Wiki analysis
  • The loot hunters take their income from was put there deliberately. One account states the Rulers created essence stones and implanted them inside the magic beasts they had captured during their first war with the Monarchs, so that the beasts would kill humans and saturate the human world with mana.▰▰▱▱▱ likely2 points
    Supports
    • It is later revealed that the Rulers created essence stones and implanted them inside the magic beasts that they captured during their first war with the Monarchs to have them kill humans and in turn, saturate the human world with vast amounts of mana so that mankind wouldn't be wiped out during their eventual rematch with the Monarchs.Essence Stones - Solo Leveling Wiki analysis

  • What happens to a gate once its boss is dead is told more than one way. One account says the dungeon stays open for about an hour after the boss is killed and then closes on its own, while others describe hunters as the only ones who could close gates and have them seal the gate after killing the boss.▰▰▱▱▱ likely3 points

    • They generally contain a horde of monsters, which are led by a boss, and remain open until the boss is killed. Once the boss is killed, the Dungeon will stay open for about an hour before closing on its own.Dungeons - Solo Leveling Wiki analysis
    • As hunters turned out to be the only ones who could kill magic beasts and close gates, a global billion-dollar industry eventually developed around them as a result and they have extremely high standings in society.Hunters - Solo Leveling Wiki analysis
    • After the dungeon has been picked clean of everything of value, the hunters then proceed to kill the dungeon boss and seal the gate.Guilds - Solo Leveling Wiki analysis
  • How long a gate can be left before it breaks is given inconsistently. One account says a dungeon break follows if a gate is not addressed within a few days, another says a dungeon must be cleared within seven days, and a third has the gate on Jeju Island becoming a dungeon break seven days after a clearing mission failed.▰▰▱▱▱ likely3 points

    • If not addressed within a few days, a Dungeon Break will occur, releasing the Magical Beasts from within into the world.Gates - Solo Leveling Wiki analysis

    • The gate spawned on Jeju Island about four years before the events of the main storyline. The Korean Hunters Association launched a search-and-destroy mission in order to clear the gate, but it ended in failure. As a result, they were unable to prevent the gate from becoming a dungeon break seven days later and the ant monsters inside the gate from crossing over into the human world, resulting in thousands of civilian fatalities and turning the island into a wasteland no longer fit for human habitation.Jeju Island S-Rank Gate - Solo Leveling Wiki analysis

  • What decides who awakens is left open. One account says there is no direct proof and only a suggestion that genetics might play a role, and another says some humans have a lower tolerance to mana that prevents them from awakening at all.▰▰▱▱▱ likely2 points

    • However, despite the fact that people are awakening almost every day, some humans have a lower tolerance to mana; this prevents them from awakening and ever becoming hunters.Mana - Solo Leveling Wiki analysis
  • Where a gate will open is not something the accounts settle. Gates are described as appearing in a range of settings seemingly at random, from highways to abandoned areas and even high schools, and red gates are described as impossible to predict because they initially appear as normal blue-colored gates.▰▰▱▱▱ likely2 points
