Legend
Maztica came back. It’s mentioned in the SCAG and Tomb of Annihilation.For some reason I think Maztica is still part of Abier and never came back. That land is now Returned Abeir or such. Although I would not want to play that setting or think Wizards would touch it again.
I can remember people complaining about how every inch of Faerûn was covered and there was nothing left to explore anymore.Everything outside of the Sword Coast in 5e has been forgotten by WoTC. Back in 3e D&D, it seemed like there was an accessory that covered a every inch of Faerun.
No matter what WotC does, someone will complain about it.
That being said, I think an Abeir campaign setting has potential.
