Warshawskium?
What even is that? How does it interact with technology? It sounds like some unobtainium or another vibranium. I always thought Warszawski's sail was genius because it was extremely sophisticated piece of engineering, like steam engine in 15 century. Now it's sound just like natural properties of material - if you put electrical current through iron it generate magnetism. If you put electrical current through Warshawskium it generate grav wave. Adrienne Warszawski is now less like an Euler with precise goal who make incredible discoveries with the power of mind, and more like Hennig Brand, who discovered phosphorus just by looking what happens when you boil human urine
Disappointing.
"“Warshawskium,” Lorra said, tossing the sample back and forth between her hands. “That’s what. It’s a rare earth, very valuable. It’s used in every gravitic engineering application. It can be produced artificially, but the process is complicated and expensive. It’s a lot cheaper and more efficient to extract the naturally occurring rare earth from the host mineral. Most people wouldn’t recognize it, but Stormy was a rock hound, always talking about how someday she’d strike it rich. Thing is, while skoldian may contain warshawskium, it doesn’t always." - What price victory?, Deception on Gryphon
