Of course, there could be racially-unique backgrounds. It can only add to the flavor.
Guess it shows why Dark Sun is my favorite setting.
Early in my D&D experience I was exposed to Thri-kreen of Athas, and it spent a lot of time making sure you understood, Kreen are not just dudes. Elves of Athas did the same thing.
I'm not saying it's right or it's wrong, but just my preference due to my early exposures.
Long as they stay in Eberron, they can be whatever they want.![]()
13th Age has them in their core setting of the Dragon Empire, but they are called Dwarf forged.
The setting of Zobeck from Kobold press has them but they are called Gear forged.
In 4e there were articles on including them in the Realms, Oerth, and Darksun.
Every setting can be a kitchen sink setting as far as the PC's go, they can play magic talking ponies if they wish and the DM is cool with it.
My Little Darksun Ponies, Defiling is Magic.
Warforged are a great example of how D&D does not typically engage demihuman alienation. By rights, you are correct, the warforged /should/ be ultra-weird, but they're not -- Eberron is pretty clear that they're just, y'know, dudes. Manufactured, metal dudes.
I'm not sold that this is a positive.
