While material from setting-books is allowed (the Forgotten Realms Campaign Setting is even part of the basic resources), setting-specific material is not. This includes, but is not limited to, the following:
Races: Warforged, Shifters, Kalashtar, Dromites
Prestige Classes: Harper Scout, Hathran, Red Wizard, most Eberron PrCs
Feats: Thunder Twin
Other: Dragonmarks
Material that has setting-specific lore prerequisites (such as “Must be inducted into an Order”, “Must be from a particular clan or region”, or “Must have Pelor as patron deity”) may have alternative prerequisites. If lore prerequisites would normally render certain setting-specific options incompatible (such as two prestige classes that requires different patron deities), the options will likely remain incompatible even if the lore is removed entirely.
