Dungeon

Just went through pixiv the other day and found about a deep floor of the dungeon. It supposedly comes from a short story divided in four parts, each of which comes in a blue ray volume of season 3. The story is called "Letter from the Heretics" (異端児からの手紙). Does anybody know anything about it?

It is possible that a goddess entered the dungeon thousands of years ago, used her arcane on him and the Dungeon made him so angry that he decided to absorb the goddess, then the goddess would be reborn as a hybrid between a monster and a god that lives on the top floor. from the dungeon. Surely I am wrong and it is not like that but I think it could be. I mean why else does the dungeon hate gods enough to summon black monsters? In addition, it would explain the birth of monsters as if they were their children, as humans and other races are children of the gods. And if we remember, Olivas Act said that he died and then "she" revived him as she did with Filvis. Revis also asked Olivas if he really saw her as a goddess, which would mean that maybe she is a corrupted goddess like the demi spirits.

I keep hearing the Juggernaut that slaughtered the Astrea Familia was stronger than the one currently because it was spawned in a lower floor, does anybody have a way to corroborate this? I always thought both Juggernauts spawned on the Water City.

During recent discussions with fans of the series, the topic of when the deep floors (floors 37+) where discovered came up. Apparently early SO states that these floors were only explored for the first time about 100 years ago.

Does anyone here remember this statement? If so, what volume (if possible, around what page) of SO is this mentioned in?

We already know that dungeon atleast has 70 floors confirmed. And there are 4 confirmed monster rex so far Goliath (lvl 4) on floor 17, Amphisbaena (Lv5) on floor 27, Udaeus (Lv6) on floor 37, Balor (Lv7) on floor 49. So following the pattern there should be a lvl 8 monster rex on floor 60. So what are your thoughts on it?

I haven't read all of SO yet, but from what I understood from vol 12 synopsis, Loki didn't know that the deadline was close. Am I correct here, or is it something that whoever did the synopsis just didn't put there? Because, if I'm correct here, then wouldn't that mean that most Gods actually don't know about the break of the vow? I'm basing this mostly on the fact that so far we have only been shown 4 gods that know about this: Hermes, Astrea, Erebus and Dyonisus. And in vol 12, before leaving, Dionysus said "that the lower world would turn into the underworld before the "promised time"", in other words, before what they used to think.

If I am wrong here and this is really just my lack of knowledge on the SO please tell me, I am just really curious on this matter, because, if I am right, I kind of have a theory for why this is it that I would like to share.

Please, if I am wrong, just say so.

how did filvis challia achieved the floor 60? are we know something about floor 60?
