You are Elle, a young member of the Steam Smugglers band of thieves, whose purpose is to bring economical balance to the social classes.
In a world where steam is the main source of energy, the Räderwerk family rises after the discovery of a new and improved technology that increases the performance of this type of machinery. When Mr.Wright won the elections for president, the highest echelons obtained more benefits and the working class was asphyxiated in taxes. There are those who point to the Räderwerk family as patrons of president Wright in exchange for becoming the owners of the country's aerial-railways lines.
With the arrival of his second son, Mr. Räderwerk celebrates his birth with a gift to his wife: the Ichita Rosë, a hybrid stone composed by a red and a common diamond, which price is invaluable. This jewel is being transported via train to the art gallery of Capital City to be exhibited, but the family does not know yet that a group of smugglers is about to steal it.
