Steamery is a type of learning, like Magery and Lettery (Magic of Written words, Scholarly works), akin to Alchemy which combined elements of the two. It is considered a type of magic, the use of the four basic elements to produce “magical” power.

I was in a game with a GM that had a Masters in History, who made is a point to mention that the local peasants didn't have wheelbarrows. The rest of the players just shrugged that off but I knew that the GM was trying to tell us the peasants were on the knife edge of starvation.
All that from wheelbarrows? Yes, because before the invention of the wheelbarrow it took two men to carry that load. In it's time the wheelbarrow was the most explosive production multiplier that the peasantry could get their hands on.
This is worth two tips: One about the power of the Wheelbarrow and the other is the moral of the story...that people need to know the point you are trying to make.
