The Machinations of Balgrum
The rune-core engine is marvel of ingenuity and in some regards another embodiment of the new age. While steam powered engines came around long before the first rune-core engines, and are still used in some areas, they have long since been replaced by the rune-core engine in Vaserde. In basic terms a Rune-Core engine allows for the manipulation of the classical elements by inscribing runes of power on various gemstones and inserting it into the control block. The engine block itself ranges in its complexity, but it usually comprises of three major components: magic, mechanical, and alchemical. The magic component, in the form of arcane runes, inscribed into granite block that cradles the rune stone, transfers and focuses the energies emanating from the runestone. These energies are directed in to etherium wiring, which are suspended in an alchemical solution, known as Vox, that weaves its way throughout the device. The clockwork-based controls allows for the manipulation of the magics contained within.The first rune-core engines were based on manipulating the flow of liquid in a cylinder. By moving the liquid back and forth fast enough in a closed container, work was achieved. These engines proved limited in their use, as even the least viscous liquids could only move so fast in a particular direction. Eventually with improvements to the manufacturing of etherium, a new double jacketed piston was able to achieve greater power. By inlaying etherium into an iron piston, filling it with vapor, and filling the outer cylinder with unique alchemical slurry, rapid compression and expansion of the vapor could be achieved. Recently other forms of rune core engines have come about. These engines have an open system, where the device takes in a certain material (usually air or water) and compresses the outlet stream. This allows for an even greater speed to be achieved but is limited to propulsion of the object only, and at speed, difficult to control.
