Has anyone considered languages? I'd presume for convenience if nothing else that most people speak a similar language for some reason, but would it be possible to include certain kind of creole for the different races? Maybe some remnants of their old languages that would still be used by a moderate portion of the race, or something to that extent.

You couldn't have a massive city without a common tongue amongst its people so I presume the race that originally built Earroldir will be the one that we all speak in addition to any languages that we would speak to our own kind with.

Also I did a preliminary sketch, having no rubber makes it a bit difficult.
