Solid, stoic and strong, the Dwarves never meddled to the same degree in the affairs of Man as did the other Higher Races. They still had their followers and their influence of man a human but withdrew to their Holds and left Man to its own devices soon after the initial rebellion. 

Dwarven, well Petty-Dwarven, is the language of science and technology. The tomes of engineers and architects use the builders tongue.
