This edition: Rosete.
This is the biocrystal which I believe would be most accessible to sapient beings, and would probably have the greatest research done concerning it.
On the one hand, it would be rather simple for people to experiment with machines capable of moving themselves.
On the other hand, integrating rosete into their own bodies would require a bit of a leap, though I doubt it would be much different from other kinds of body modifications humans have done throughout history, such as piercings and tattoos, or even simply armor. Indeed, sapient beings would likely quickly realize that rosete is flexible and durable, certainly at comparable to bronze or iron in the latter and better in the former quality, and thus makes good armor. I imagine inventors would continue developing this armor, discovering that it improves strength and stamina the more closely it’s integrated with the body of the bearer.
Eventually, inventors would be growing rosete inside the body, rather than on it, and would reach the asymptote of effectiveness.
Or perhaps other biocrystals would be the first to be integrated into the body. I imagine different kinds of prosthetics would be the first integrative biocrystals: false teeth, false eyes, prosthetic legs, hand-hooks, etc. A person who had lost an eye and placed albate in the socket would soon find that after some time they could see again; a person missing a leg would find the rosete replacement even better than the original. It would only be a matter of time before healthy individuals started experimenting to gain the same kinds of benefits.
Certainly with rosete’s benefits to physical abilities, it would become possibly the most common biocrystal, as armies and factories integrated it with soldiers and laborers to improve their physical prowess, and thus their efficacy in battle and in work. Perhaps this would become something applied to every member of a society — though that would require a massive supply, and likely in a scarcity, that rosete that existed would first go to special forces, bodyguards, and other very important units.
But, again, one of the most common, so scarcity would probably be a small issue.
Combining this with albate batteries, cerulite, and rubrite, one could theoretically make a factory, a proper industry. This certainly wouldn’t be an application discovered quickly, and I’m not sure how this would work with the standard timeline of technological progression — that is, if it would arise earlier or if it would take until an industrial era to get going. I’m also not certain as to the energy efficiency of the albate battery (as I may have mentioned previously), as a not insignificant portion of energy absorbed by the battery would be required for sustinence of the albate itself. Certainly an equal mass of coal or oil would net greater energy output than albate, but albate would be clean, renewable energy. Plus, you could make an albate roof and be set, perhaps.
Thoughts? Possible exploits or applications you’d want to try out with rosete? Please don’t hesistate to comment and such.
