Our visitors from Thalion, meanwhile, were schooled in the largely concealed field of sorcerous science, a scholarly realm that only those who truly master magic could reach. Its core fundamentals were proposed by the Thalion emperor Elmesia's mother, a genius elven researcher. Her teachings had been inherited and replicated by a large number of people. The field even ventured into the philosophical, exploring just how far one could wrangle magic to change the world and its natural laws. It's the sort of thing Diablo would love, I'm sure. The true worth of this theorizing, however, was in forcing certain alterations to preexisting phenomena, which would help advance the field of spirit engineering in turn. You needed to be a true expert in elemental magic to even begin to understand it, but the potential benefits went without saying. (What also went without saying was that Thalion kept it strictly confidential, prohibiting anyone from revealing its secrets to other nations.)
