Many dwarves from Terakol are a hard-working and quite ingenious mechanical engineering bunch, though they can be, shall we say, highly eccentric. Take Cesol, for instance.
Cesol lives just outside the village in which Matt and Alex live. Nobody's quite clear on when he moved there or why. Cesol himself isn't too sure, but regardless, he found himself what he considers a good place to experiment and everyone's glad that place isn't directly inside the village.
Cesol spends most of his time in his workshop happily building things. Some are useless. Some, like his steam engine cart, are useful. Others are somewhat indescribable. Some can be dangerous. Very few are dull. In practice, only the useful stuff really gets much action. Which, I suppose, is sort of the point.
