Name: Emily Delumia
Emily is a young Netopian woman, and the youthful-looking type of girl that could still pass as a teenager unless asked for her age. She's 5'8" with a surprisingly nice figure given her occupation, having respectably average curves for her height. Emily likes to attribute her good physical shape to the concept that smart people should know how to take care of themselves. Her dark blonde hair is fairly long, reaching down to her shoulder blades, but Emily rarely does anything to fix it up. If anything, her most used hair accessory is a pen she'll tuck behind a few strands for temporary storage, only to promptly forget about until Mir alerts Emily to its presence when she tries to go outside. Emily's bangs are pretty long along with the rest of her hair, and would probably get into her reddish-brown eyes often if she didn't have them parted to her right.
Despite having closets full of clothes, Emily tends to just favor blouses of various colors and cuts and denim capri pants. Worth noting, however, is a caveat that Emily wears white lab coats regularly in compliance with NAXA scientist dress codes. She does have a few collared shirts and skirts to wear on work days, but on more than a few occasions she's irked her elders by just throwing a lab coat over her casual wear. Her shoe rack is pretty expansive like the rest of her clothing options, but at the end of the day every shoe Emily owns can just be slipped on with no fuss, knots, or zippers. Though Emily's natural eyesight is not bad, she does own a pair of reading glasses as retribution for spending a few too many nights of her nerdy childhood crowded over a physics book. She does keep a medium-sized purse with her usually, though instead of whatever girly stuff might be inside for another woman, Emily's PET, Battlechips, and wallet are kept company by a variety of scientific tools and a few paper notepads. She just really can't stand drawing diagrams on her PET's screen.
What is the kind of girl that was called a prodigy as a child, and then a genius as an adult when she broke past lightspeed? Eccentric would certainly be a possible choice, though it's not really accurate for Emily. She's really pretty down to earth as a person... just with her thoughts up in space. Emily is very passionate about her work as an astrophysicist, having loved outer space as a child and followed in the footsteps of her maternal uncle and tenured NAXA scientist, Dr. Walter Neimann. That passion turns into intense focus when she's studying a phenomenon or solving a problem, so much so that Emily sometimes tunes out everything and everyone around her. It's not THAT spontaneous an occurrence, but if Emily gets an idea, she will stop what she's doing to make notes on it if at all possible.
Dr. Emily Delumia sounds... unapproachable, almost, but if you get to know her, Emily really is as human as anyone else. In other terms, that means she has plenty of flaws to compensate for her scholarly genius. She loathes literature as a subject of study, her cooking tops out at boiling water and using the microwave, and she is really quite bad with money, for starters. To that last point, keep in mind that this girl, going as far back as high school, has had hefty research grants at her disposal, and is now making doctorate money off of NAXA. The value of a zenny has never really registered with her, so Mir does all the personal budget work on Emily's behalf. Emily genuinely appreciates Mir as her Navi, partially for a lack of friends elsewhere since her colleagues are all twice (and sometimes thrice) her age, and the rest of her generation is still in college for the most part. More than once she has been a guest lecturer at a university, speaking to an auditorium of students older than herself. A healthy friendship with Mir and true dedication to her work has kept Emily from dwelling on the matter too much, but it probably wouldn't hurt if she just got the opportunity for some people her age to see her as one of them.
The Delumia Theory of Relative Lightspeed: Relative to an environment at lightspeed, a particle capable of maintaining constant position within that environment is at rest. A force exists such that contact with the particle will impart an arbitrary positive acceleration on the particle, removing it from rest. To an observer outside the lightspeed environment, this particle is moving arbitrarily faster than light.
Emily has been immersed in astrophysics almost her entire life, thanks in no small part to Uncle Walter/Dr. Neimann. She herself penned the concise Delumia Theory at age 15, drawing reference from several old and antiquated post-lightspeed theories, but it was little more but science fiction with talk of this magical particle that existed only at lightspeed. Naturally, it took the prodigal child but 6 more years to discover this particle, self-dub it the Lumian, and effectively launch herself straight up to a PhD in astrophysics and a position at NAXA almost at the speeds her new particle was achieving.
Functionally, a Lumian is seemingly much like a photon or tachyon, with the key exception that if the Lumian does have a ceiling on its speed, it has yet to be calculated. Applications to physical matter are between few and nonexistent, but early experiments into deep-space transmission have yielded entirely negligible lag throughout the entire solar system and even a lightyear or so beyond that. Emily's theory and particle discovery jumped NAXA's interstellar initiatives forward several decades at minimum, such that they're already on the verge of transmitting Navis via Lumians into the interstellar reaches of space.
Emily's PET is NAXA-issued, and thus far beyond anything one would find on the open market. It is a custom-built silver and orange model that has a wide screen despite its compact design, and is capable of true lightspeed communication that offers effectively instant data transmission over any practical range. Hmm? Why doesn't the faster-than-light girl have a faster-than-light PET? Ask Emily that and she blames the atmosphere, saying it doesn't like moving at lightspeed. Still, for what Emily uses it for, the PET is lag-less and it doesn't get much better than that. It has a few other practical functions, as well as custom programs used to measure and monitor the various Lumian simulations Mir provides.
