The youngest convention other than the Ivory Tower, the Electrodyne Engineers are inventors, scientists, and engineers whose goal is to push the bounds of scientific understanding as far as they will go and apply what they have learned to the problems plaguing humanity. Much more theoretical and less concerned with aesthetic issues than the Artificers, the Engineers are slowly pushing out the older convention, assimilating its newer members into its own group. This has led to no end of rivalry between the two conventions and the two are some of the more vocal members of both sides of the Mason-Royal Society rift.
It is unsurprising that almost all of the members of this convention are members of the Royal Society, both the covenant and its mundane reflection, and it includes some of the most brilliant minds in science in the English-speaking world. A few of its members have aligned themselves with the Masons for religious reasons or to protest the growing influence of the Ivory Tower over the Order, but these are by far the exception to the rule. For the most part, the Engineers are content to persue their theories and their research and ignore the politics and intrigue of the rest of the Order.
While the convention generally gathers with the rest of the Royal Society, at Burlington House, one of the smaller groups calling itself the Difference Engineers meets at Somerset House, where the difference and analytical engines have been constructed next to the Department of Records. Here, they collate and analyze the massive amounts of information collected by the government and by the other conventions (particularly the Ivory Tower). Although it is a fairly humble operation, as of yet, it is quickly making a name for itself with its startling results and, even more, its sobering predictions about the potential of their machines.
