Comment by Liliane on The Player Hides His Past - Chapter 87

As everyone knows, rifts are a space between archana and reality and they do not affect ordinary citizens (normal ppl can't enter or properly see a rift), but rifts known as anomaly space have types, like in Teffern Labyrinth as the name say's it's a [Labyrinth] type rift which has many deadly traps and usually hides treasures at it's center, and here in london, it's a [Dungeon] type rift which is more dangerous than [Labyrinth] type ones. [Dungeon] type has dozens of paths and it has deadly traps as many as [Labyrinth] type ones combined with many monsters as strong as the [Predator zone] level monsters (Predator zone is a place where named/boss-level monsters from all nearby regions constantly fight each other). To clear a [Dungeon] you need to find the dungeon core located somewhere inside it, [Dungeon] gets more dangerous depending on it's size and because the entire london has turned into a [Dungeon] type rift you need to find the core somewhere across the city, and since it's a [Dungeon] type it's able to trap normal citizens who's not supposed to be able to enter a rift which is why it's highly dangerous. But since demons are involved + getting information from the AAU everything just become easier for homen lol.

There will be more types of rifts like [Battlefield] type where you need to choose a faction just like in the battle between dwarves vs flauros(ch75) or [Colosseum] type ones, but those can be explained later
