What would you like to see from a future story arc? (Spoilers)

[Turethir]

I'm far more interested in the Source than the shards, so for me it would be Meracydia and Ilsabard that would be top of the list.

If we do go to a shard, I really hope it can be its own place with its own unique cultures rather than being particularly associated with one FF game, like they did with the Void/IV and with Dawntrail.

I'd personally like the Scions to stay with us, but in groups of 2-3 at most per expansion and to rotate out as needed.

Personally, I'd rather enjoy a storyline where we use the 'key' (assuming that we figure out how it works at some point during Dawntrail) to visit another shard and, as you say, discover a interesting culture.....
but have the visit end with something happening that results in the key doing something that sends us back to the source, but not the point where we left - it drops us in Meracydia... except we don't know it's Meracydia; at least not initially. I mean, we know very little about Meracydia's (as Emet-Selch said) "current state of affairs" and the implication was that the only way we'd find out would be to actually travel there.

We'd have to figure it out eventually - evidence of the Allagan Empire and the presence of Dragons would give the game away, but it would be interesting to have a Shadowbringers-esq 'arrive in a strange and unfamiliar, place' start to a story again.
