Speculation - 6.X trial series

[SeverianLyonesse]

Given the release of Stranger in Paradise, they could do a trial series for the original Four Fiends - Lich, Marilith, Kraken, and Tiamat - though they'd have to alter at least one name.

Two, really: Tiamat and Kraken. I was thinking about whether that would be an option and could even be directly tied into the Tiamat we already know. But that would still probably require finding some justification for bringing back Kraken from Sastasha/Hullbreaker.

I guess it's doable, but it would require a lot of writing gymnastics. But if done well I guess I wouldn't mind.

EDIT: Actually, now that I think of it, this may be one of the more likely options. When I look at what we have already gotten for extra trials and raid content, I see:

FFI:
FFII: Pandaemonium
FFIII: Crystal Tower
FFIV:
FFV: Omega
FFVI: Warring Triad
FFVII: Weapons
FFVIII: Eden
FFIX: Alexander
FFX:
FFXI: Eureka
FFXII: Dalmasca

So my best guess would be anything from FF I, IV, X, or XIII. And since EW already heavily features IV and X, I is almost the obvious choice by process of elimination (unless we are looking at forging into new territory with XIII/XV). It would also make for a pretty fitting capstone to the 10 year arc.

Also, looking at this list I would imagine we might eventually get some sort of Lunar Subterrane and/or Sin set of trials/raids.

Don't forget Hildebrand in ARR. The quests were longer than most later trial series, but they still fit the pattern.

I guess loosely, but I also kind of discount everything in ARR since the patch cycle formula really wasn't clearly defined at the time. And it feels weird trying to classify two Gilgamesh battles and an Ultros/Typhon battle as fitting the same mold as the expansions, which each dealt with sets of different high-level bosses from a specific title.
