Okay. When i first looked the Warhammer FB wiki seeing no trivia involving no copyright parts to Tolkien about Halflings in WH.
The Halflings in Age of Sigmar are probably or temporarily extinct due to the destruction of the Old World and its moons.
Mootland is gone because of the Old World's destruction by the Chaos Gods including Slaanesh.
What i'm thinking of that there will be no more Halflings in Warhammer (There's also Ratlings from 40k) because of copyright to Tolkien.
In the future of AoS fans, fans can call their own AoS Halflings Shortkin or Shortmen. But not Gnomes actually.
This blog is about Lore to Age of Sigmar Halflings being extinct.
What i'm guessing is... that you can find Halfling models on Google or eBay.
Besides, the Halflings in Warhammer are no more.
But further doubt that new years, there will be no Halflings in WH anymore unless someone can start sculpting models of them for AoS.
Feel free to comment on this lore about No Halflings so that i can read them, please.
