Dungeons.
Even before the recent worldwide system upgrade that occurred in New Earth, dungeons had always been a part of New Earth ever since the apocalypse began.
There were various types of dungeons, and an example of a dungeon was an Open Dungeon.
An Open Dungeon was a dungeon that most people feared because of the danger it possessed.
Unlike Closed Dungeons that could only be accessed by entering its portal, Open Dungeons were... well... open.
The monsters in Open Dungeons were free and could leave their abode with ease, and anybody could also enter an Open Dungeon with ease.
An example of an Open Dungeon was the current mountainous region Corey was in.
Trollspire Dungeon.
Trollspire Dungeon was a popular open dungeon that was close to the edges of the Haven Continent.
