Hasbro doesn't want to update DS to sell more sourcebooks but to use the IP for different types of products, mainly a future videogame style BG3.
And it is the harderst to be updated because both crunch and fluff. The banning of classes and PC races is against the philosophy of 5e and the lore...
I asked Gemini an image of a D&D group inpired in the cancelled toy line: "Sectaurs: Warriors of Symbion"
And "Golden Girl and the Guardians of the Gemstone"
This time ChatGPT an image of a Planescape group based in Rick & Morty.
Excuse me, vuestra merced, because I started to learn English when I was in 6th grade and in more twenty years reading English in internet and some RPG sourcebooks in original English never I had seen "them" used for singular, but Franky Stein, character from the action-live of Monster High...
If the group of magical girls "Pretty Cure: Glitter Force" were a group of kenders in Dragonlance.
Hasbro has got a lot of forgotten and unused characters, franchises and IP what could be recovered and reintegrated into D&D multiverse thanks a right redesign. For example "Star Fairies" could...
Autognomes are constructs created by gnomes from Spelljammer setting. They are like the shorter but older cousins of the warforged from Eberron. They weren't a playable specie until 5e.
When I saw the blue (a gobling subrace) in the Expanded Psionic Handbook I wanted to create my blue PC...
Some times I imagine using a nerferd version of jump spell like a cantrip, or riding monster mounts or constructs.
They are right like nPCs for "cozy" zones.
Do you mean any thing like the "Sundering" in the Realmspace (FR)? Yes. Maybe it is Vecna's fault. The time travel was official in DS 2nd, and without any chronomancer guild working like timecop Athas could have suffered its own version of multiversal war.
The Athaspace is not in the same...
I don't advice NSFW scenes in the tabletop even if the rest of players are adults. Today with rule34 you could find images of She-ra and Katra ... but most of audience would rather (sfw) romances like Tanis&Laurana, Riverwind&Goldmoon, Caramon&Tika, Gilthnatas and Silvara or Drizzt&Catti-brie...
The official lore in 2nd Ed could say something but you can hope it will be retconected or rewritten. They'll invent some excuse to justify the presence of aasimars, for example the result of a successful ritual for a reincarnation spell as a reward for the most loyal and competent servants.
This seems like a conflict between continuity and gameplay, coherence with the lore or flexibility for fun. In my own tabletop I rewrite the lore because like this I enjoy D&D.
I dare to say the sorcerer-kings can produce water if they want, but they would rather to keep the monopoly to control...
