I think that it disappeared because not all of the people who had the Gaia skills where there. I think to enter the black portal at the end you had to have a Gaia Skill. But that my theory.
I think that's a pretty great theory! In my theory, i feel that the great dungeon that they have predicted isn't the same dungeon years ago. But I also feel like they haven't actually cleared the great dungeon from years ago due to the fact a portal appeared inside it and "disappeared"
I also have a theory about the guy who was supposed to exit with the 4 that did. I think he stayed in the dungeon. And that premonition that shows 1 person walking into the black portal. It's him.
I wont really spoil but ive read the novel and honestly youre very freaking close

what chapter is manhwa 56 in the novel? (estimate is fine)
Wooshhh!! I'm excited to know what happens :33
I cracked. I'm reading the book now. Oh are close either our theories.
Nah you have to fucking give me the light novel PLEASEEEE
So say truly I had the exact same thought as you because it's suspicious that mc doesn't know where the 4th guy is despite all of them fighting that huge dragon together AND him sawing the 4th guy there alive and well
Wait I got like a theory, there was another portal that opened inside the great dungeon when they cleared it. The portal looked like it disappeared and I feel like someone used their skill to make the portal reappear in the future where they have even greater chance of clearing it due to all the new technology or something.
