Lem's parents were themselves pathfinders and he spent a fair amount of time on the road as a youngster. They also saw to a more formal education at home (Absalom) while they were away. As a result Lem is very passionate about the Pathfinder society and the expansion of knowledge for which stands. He has a particular interest in the natural world and cataloging its many curiosities. He certainly finds magic useful and helpful, but sees it as his personal role in the society to more broadly disseminate what many would consider mundane knowledge about the plants and animals of various locals.
As Co-Venture Captain of the Society's Flying Lodge he is able to conduct his field research with maximum logistical support and creature comforts.
