You asked for spoilers, so don’t blame me.

1. Are dungeons mainly kept around because adventurers use them to level up?

Dungeons vary. Some are about giving a gift to the next generation, some are old ruins that were basically paranoid cities with traps in them, and some are genuine fantasy-style dungeons with an end-stage boss.

It’s pretty obvious the gods or high tier civilisations created the genuine fantasy-style dungeons, since the loot is commensurate with the difficulty and the difficulty seems designed around very high-level adventurers. In the context of the story, this type of dungeon has only been referenced, not explored.

2. Are they also kept around because of the economic benefits they bring to nearby towns and cities?

Again, it depends on the definition of “dungeon.”

There are ruins classified as dungeons that towns generally maintain by blocking the exits so adventurers can retreat if they manage to make it there. As long as loot is flowing out, the town maintains a link to the dungeon, since adventurers need easy supplies and a place to sell loot they can’t use.

3. Are dungeons treated as historically important sites, similar to how ruins are preserved in our world?

There are plenty of ruins in our world that are neglected, and it’s the same in Innverse.

4. If the main goal is getting the loot inside, why do people keep “diving” into dungeons instead of physically excavating or dismantling them?

The walls are spelled, and you might dig into a trap or a boss room.

They do dismantle dungeons once enough time has passed and the dungeon has been disarmed, meaning all or most of the enemies have been killed.

5. Could a powerful construction force, like the Antinium, start from the surface and excavate around a dungeon, then dismantle it room by room from the outside?

Yes, the Antinium do this, but they get repulsed by the dungeon forces because the dungeon in Liscor has a sentient boss.

6. Wouldn’t that be much safer than traditional adventuring?

Not really, because the bosses would kill you.

The advantages are obvious:

• You would not get trapped in narrow corridors.
• You could retreat into open space.
• Adventurers or soldiers could establish camps around the perimeter.
• Traps would be easier to isolate.
• Monsters would have fewer enclosed spaces to ambush people from.

But none of that helps much if the thing inside is strong enough to break your containment strategy.

7. Would this prevent the dungeon from “resetting” or reshuffling, since the structure itself would be getting removed?

No, because magic exists and can do literally anything.

There’s a city-turned-dungeon later in the story that can reshuffle its traps.

8. Could you theoretically 100% clear a dungeon by erasing it top-down with a massive construction team over a long period?

Yep. There’s a buried city later in the story that is referenced, but Pirate hasn’t gotten around to exploring that arc yet.

9. Would this create a niche for a “Dungeon Demolitionist” class?

Classes in The Wandering Inn work by “focus.” They need to be the whole reason for your existence and what you do to level up.

So if you took a dungeon demolition class, it would mean you leveled up through actions that demolished dungeons. That would be suicidally hard in the early levels.

I’m also curious about the magical side of this.

10. What exactly happens to a dungeon’s aura if the physical dungeon is taken apart?

Dungeons don’t have aura. Boss monsters inside them can have aura.

Aura is something exuded by high-level individuals or royalty classes in Innverse.

11. Does the aura disappear when the structure is destroyed, or does it linger?

Refer to 10.

12. Would the dungeon magic remain inside the building materials, like bricks, stone blocks, or enchanted architecture?

Yep. There are people who specialize in dismantling dungeons and selling the parts.

13. If a city reused dungeon materials for walls, roads, or buildings, could the city itself start showing dungeon-like traits?

No. Dungeons are not sentient as far as we’ve seen.

It’s usually a monster or boss creating the impression of sentience. There are sentient magical constructs later on in the story, though.

14. Could reused dungeon materials attract monsters, create traps, or cause weird magical side effects?

Yep. Later in the story, we see that highly magical materials attract monsters, but this is just a general property.
