Hooke's Law (A)
One of Caster's greatest contributions to the world of science. This law states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. It is said to be a precursor to both the laws of elasticity and Newton's third law of motion. This Skill allows Caster to form barriers capable of absorbing force and reflecting them back to their origin. By using more mana, she can increase the value of k in her barriers, doubling or even tripling the initial force before reflecting them. That said, similar to how a rubber band could snap if stretched with too much force, these barriers possess a set value of durability and may shatter if said value is surpassed within a single hit.
"See, I came up with that first! About a whole decade before Newton came up with his Principia Mathematica! And they say I'm the one plagiarizing his work!? It's just like those moments where people applauded your friend just because he said your joke but louder! The nerve!"
Scientific Insight (B+)
A composite Skill consisting of Inherent Insight and Expert of Many Specializations, particularly in the field of science. A natural prodigy, Caster made contributions in physics, biology, mathematics, chemistry, architecture, paleontology, and neurology. This Skill allows her to to grasp the essence of things. In the case of being used against Servants, should the luck check succeed, it will see through the truth, even one firmly concealed by means of magic or Noble Phantasms. This effect is further strengthened while her Noble Phantasm is active.
"I believe science is simply a matter of connecting one thing to another until you reach a satisfying conclusion. There are countless ways to do so, but as long as you follow the proper scientific methods, step by step, I'm sure you can accomplish anything you set your mind into... unless you're Newton. I swear, that hack just got bonked in the head one day and it's as if a lightbulb just went off in his head! Then he pretty much skipped everything until the last step, and got famous for it! Even I must acknowledge his genius, but- ugh, just how the bloody hell did that happen!?"
All Portraits Must Be Burned (Revisionism) (B)
In life, it is said that Caster was engaged in bitter rivalry with fellow scientist Sir Isaac Newton. She allegedly plagiarized some of his works, and the two frequently published slanderous accusations directed at each other. So great was Newton's enmity towards her that after her passing, he burned every letter, book, and portrait mentioning or depicting her in any way, as if trying to erase her entire existence. While a number of these books and letters were salvageable, none of her surviving portraits remain. Such is the extent of their bitter rivalry... or is it? There seems to be several questions left unanswered on the topic. For one, how did history remember Caster as a man named Robert Hooke? Furthermore, Newton himself even promoted some of her works posthumously, an action which contradicted his previous attempts to discredit her. Whatever the case may be, perhaps there's more to this rivalry than meets the eye...
This Skill works in a manner similar to Information Erasure, obscuring Caster's identity, parameters, abilities, and traces of her actions unless one has them recorded and makes an active effort to remember her. This erasure process spans a few hours, and even if one were able to piece together evidence of her existence, unless the previous measures (recording and remembering) are met, their minds will instead conjure the image of "Robert Hooke", a grumpy old man with an image wholly unlike Caster's own. As a Servant, this Skill is extremely useful, allowing her to operate under the radar and divert suspicion from herself. As a scientist who wishes to be acknowledged for her own efforts, however, this Skill is more akin to a curse.
"I know I should thank Newton for what he did, for crafting the idea of 'Robert Hooke', but now I feel as if I simply moved one step forward and two steps back... Oh well, ruminating over the past won't change anything. I'll just have to come up with something so great that the world will finally remember me for who I truly am! The same goes for you. As my lab assistant, you better not forget my name, you hear me!? The moment you call me 'Robert' or even worse, 'Newton', you're fired! Write it down with a permanent marker on the back of your hand or something!"
Pioneer of the Stars (EX)
A unique Skill given to heroes that became turning points in human history. All difficult voyages and challenges which are considered "impossible" turn into "events that can be realized". While Caster is not as well-known compared to her contemporaries such as Newton, Boyle, and Newcomen, it's undeniable that she influenced their works (to varying degrees) and stimulated growth in various other scientific fields. In that sense, even if she never quite came up with any universally groundbreaking discoveries, she planted ideas that would make way to numerous major scientific advancements, benefiting humanity as a whole.
"This is it; the only proof of my existence not tied to Newton or 'Robert Hooke'... Gender, status, and origin aside, the contributions I made speaks for themselves. Yet as much as I'm honored to be immortalized in this manner, well... many scientists were content in passing the torch to the next generation, knowing that their works would pave way to even more discoveries in the distant future. I can't say I entirely share the same sentiment. Even now, I'd like to continue looking for answers, conducting even more experiments, and unveiling even more mysteries of the world. At the end of the day, regardless of my title as professor, scientist, curator of experiments, and everything else, I'm just a selfish girl obsessed with finding out everything there is to know about the universe around us, and I'm proud to admit that!"
