If there is some good reason for a new setting is to be unlocked in DMGuild.
My suggestion is an update of Councyl of Wyrms where Io's Blood Island is a cluster of demiplanes within the elemental limbo.
Witchlight is practically other mini-setting, or potential setting.
If WotC wanted a...
The Brasilian soap-opera "God save the King" could show us an idea of how would be a Birthright romantasy story.
It is possible but the key is to write a right plot, and the best writters would rather start from zero with their own IPs. And it couldn't be only a couple but more to allow...
3rd Ed had got Eberron and 4e Nentir Vale/Points of Light but a 5e setting should be designed to allow space for future crunch like new PC species and classes. If, for example, WotC wanted to update the martial adepts (crusader, swordsage and warblade) and the incarnum soulmelders (soulborn...
I am not like the ordinary players but more like a collector but if I buy a sourcebook I want this to be a source of inspiration for my own stories.
In some cases the metaplot has become a straitjacket for the creativity. The group of main characters change the world and the rest becomes too...
Teorically the kenders should extinct because they are too daredevil and imprudent to survive serial killers and other supernatural predators from horror movies but some females kenders who needed money started to work as gravure idols (only legal SFW pictures) and then... they became too...
If a kender and an Athasian halfling wear the same cloths, could you notice the difference with only to watch their faces?
I am also interested into lands around the region of Tyr but the Dead-Land is too hard to be explored. At least in the zombies apocalypses you still can find food and...
Surely Hasbro is the first one who wants a new videogame like BG3 but this needs a right team, time and money. I have said a DS videogame would be a survival style "Conan Exiles with psionic powers".
* Maybe no-halflings could survive the cleasing war because they could travel to other worlds...
Can we use the tag "Hyborian-punk"? Because this setting is like a mixture of Mad Max and Conan the barbarian.
We could create an "Athasian" version of other setting, and here we could enjoy total creative freedom to add and remove things as we please but I suspect one of the key elements are...
Let's remember the action-live serie "Once Time Upon" what was a complete reimagination of Disney tales.
A mash-up setting may need a new geography of the continents starting completely from zero. Really it would be more like a spiritual succesor of both previous franchises. We shouldn't worry...
The alternate Dragonlance timeline "Istar triumphant" based in the short story "There Is Another Shore, You Know, Upon the Other Side" allows a lot of changes to be closer to the DS style. For example if the gods of magic lost their divine powers then the consequences would be serious. Now the...
