A Title Much Cooler Than Anything on the Old Site
Or gods. If Dwarf have innate stoneworking skills, that fact that peoples are given certain languages by their creators are not that much more of a stretch.The idea that everyone is speaking a trade language/second language makes a lot more logical sense, but this should make conversations stilted and largely without idiom. Which rather runs against the "fun" aspect of D&D.
Not really my experience. Most D&D settings I've experienced are pretty much like FR. Exandria for example. Or Spelljammer, Krynn or Greyhawk. They are all quite extensive, and most don't have the communication/transport networks of Eberron.
It would probably make more sense to invoke universal translators, babel fish or Tardis telepathic circuits.
