Nightmare Dungeons are coming (Not the Abyss Nightmare, but dungeons that are truly "Nightmare Dungeons"). Will be extremely difficult unless you have a full party of 99s, maxed RD, maxed Honed abilities and each game series will get one (so my bets are on the final boss fights for each series), they will have their own special imperial enfeebs and mechanisms, they will return every month so don't worry if you can't clear, please look forward to it.

Edit: Gonna just copy/paste some of the reddit translations for this, very interesting.
Mechanics
Nightmare dungeons are a new tier of difficulty beyond what we've seen before.
Clearing them at your current level will be very difficult.
All series will get a Nightmare in order. (The kanji means numbered order but I am kinda doubtful that they'll really go FF1->FF14 and then FFT.)
If you can't clear the Nightmare now, it will come back at fixed times when the next Nightmare is added.
Something about each Nightmare dungeon boss has its own Enfeeble mechanics (what we call Imperil) but I don't know if that means "bring your Enfeeble and elemental team" or "the boss will Enfeeble you and follow up with your new weakness"
You can expect to clear this if you've got characters' MC3 caps broken, you've spent your RD fragments wisely, and you've honed your abilities effectively.
Last blurb: The Nightmare dungeon is a long-term extremely high difficulty dungeon series. Please look forward to it.
Stamina
Minimum max 60 sta before you can challenge Edit: Correction, Reddit posters translated it to mean: "Only people with a max stamina of 60 minimum will be able to do these fights", So the minimum stamina for these fights will exceed 60 stamina it seems.
Story
Battles were won and heroes had saved the world.
Nevertheless, these battle were without repercussions as this fierce battle has carved "nightmares" into the heroes.
Hatred, sorrow, and regret plague the hearts of these heroes and have wiped their memories.
Strong "nightmares" which are the shadows of these heroes of light yearn for them to imprison them in their dark "nightmare" world
Rewards
Not translated, but "Advanced Fragments" are mentioned
