DragKraft

DragKraft is a term used primarily in speculative fiction and certain role-playing games to denote a system that channels aerodynamic drag or dragon-derived energy into usable power or propulsion. In many works, DragKraft refers to either a discipline that enhances flight and speed by manipulating air resistance or a fictional energy source derived from dragon physiology or magical fields. The exact mechanism varies by setting: some depictions present DragKraft as a finite resource stored in artifacts, while others treat it as an ambient, accessible field that can be tapped with training or devices such as harnesses, gauntlets, or exosuits. Practitioners often perform specific motions, rites, or sigils intended to optimize drag conversion, drawing parallels to real-world aerodynamics, wind energy, or sail dynamics.

Origin and etymology: The term blends the German words Drag (drag) and Kraft (power/force), and appears in modern fantasy, science fiction, and tabletop literature as a way to evoke both dragon lore and physics-based propulsion. It is typically presented as a fictional construct rather than a real-world phenomenon.

In-world depiction and uses: Authors and game designers use DragKraft to power aircraft, dragonsuits, or siege engines, enabling sustained flight, sudden accelerations, or energy-based attacks. The concept often raises questions about energy balance, safety, and the limits of manipulation of air resistance, providing a flexible plot device.
