Overview
A techno-magical being from a nearly-dead world, Emily Nyx spent some time gaining power out of boredom, and then decided to head into the World Tree when she found out that it was possible to leave the halcyon remnant. She's somewhat amoral, but she prefers to play the hero because the consequences of being a villain would just be a pain. In addition, she takes great pride in being a total weirdo, and has a very bizarre sense of aesthetics and what constitutes "cuteness." (On the other hand, there are some obvious holes in this behavior, such as the fact that she immediately becomes embarrassed if someone expresses distaste for the way she addressed them, and the fact that it would be even easier for her to sit things out rather than participate on either side ...)
Perks
Greater Eudaemon: She's a more-or-less immortal shapeshifting techno-magical being.
A perfect blend of magic and technology, Emily is a cluster of nanomachines wrapped around a central CPU core, making her unaging and immortal barring violence or accident. She can shapeshift into any form she likes, as long as she doesn't go over a certain volume; she isn't going to fool anyone with any kind of enhanced senses or scanning-devices, whether magical or technological or anything else, but whether she takes on the appearance of a human in a dapper suit with an even more dapper sword, or that of a tentacled robo-monster, she's gonna insist on looking look good. As a Greater Eudaemon, she's considerably more powerful than her peers, but this ironically makes her more vulnerable; while most Eudaemons take damage to their nanomachines, in Emily's case injuries are inflicted on her "self" instead, thus placing greater stress on her CPU core. She was to be a servant of the Masters of her world, but her construction was completed soon before the mysterious that wiped them out, and she was only activated for the first time sometime after it.
Inertial Manipulation: The power of flight.
A force field effect which exists primarily for the purpose of transporting around her nanomachines under her CPU core's power, and secondarily so that Eudaemons don't need to have ladders or lifts and suchlike. Emily can hover, moving with quick and precise movements; she can also glide forward reasonably quickly, though she can't quite turn on a dime.
Directed-Energy Beams: A Eudaemon's weapon-of-choice: lasers.
The lowest-hanging fruit of offensive capabilities in the halcyon remnant is firing bolts of golden light. They can be summoned anywhere in a three-meter radius of her CPU core and launched in any direction, moving in straight lines. They range from weak bolts which merely pack a bit of a punch, to powerful beams which can tear holes through things.
Capacitor Seals: She puts on a series of magical seals which lower her power.
If Emily keeps her output at maximum for too long at a time, it puts a strain on her CPU core. Her solution, as one of the first Greater Eudaemons, was to create a series of three Capacitor Seals lowering her power. When all three are active, she's barely capable of combat. They must be released or resealed in order, and the process takes several seconds.
Dimension Fields< Edge-E >: She can open short-range portals, and hitch a ride on vines.
A nearly unique ability of Emily's: she can create portals called Dimension Fields up to three meters wide, which allow her to teleport short distances. It takes a second or two to open one up, and she needs to be consciously aware of her current location relative to her destination, which usually means line-of-sight. The exception to this is if she uses a dimensional field to insert herself into a Vine (which is largely more style than substance), in which case she ends up wherever the Vine would normally send people, and it isn't possible to see through them. By expending Edge, she can also teleport into heavily fortified and shielded areas, but again, she needs to be consciously aware of her destination.
Timestop Templartifact: A malfunctioning signet ring for stopping time.
Emily looted a technologically-advanced signet ring called The Timekeeper from the corpse of a member of the Templar Order, which granted the wearer the ability to stop time; however, it was damaged, and the repairs have not been completely successful. In its malfunctioning form, it creates a sphere about a couple dozen feet wide or so, fixed in place and centered on wherever the ring was at the activation time, within which people and objects are frozen in time; those within this sphere are still capable of perceiving the stopped time. Those who are in physical or magical contact with the wielder are able to move in the stopped time, anything they're touching can also move, and so on. However, inertia is not transferred between objects, and thus Emily (and anyone else riding on the power of the ring) cannot use melee attacks. If the wielder leaves the area of effect, time resumes. For various reasons involving physical contact, the only abilities Emily can use while time is stopped is flight, her Directed-Energy Beams, and her holograms, and even then, lasers become frozen in time. The ring is somewhat finicky and unreliable, and usually doesn't work for more than a few subjective seconds at a time, especially when more than one person is touching her.
Observational Skills: She's good at noticing the little details.
Emily isn't a genius by any stretch of the imagination, and she's lacking in common sense about worlds that aren't the halcyon remnant, but she can pick out and pay attention to little details that others might miss. She's also reasonably good at putting two and two together, although sometimes her conclusions are a bit off-the-wall due to said lack of common sense, and she can't always see the forest for the trees, either.
Nano-Tools and Holograms: She can create tools and weapons, and project holograms.
With a mixture of nanotechnology and magic, Emily can create clothing and simple tools or mundane objects without their own magic or electronics (which can include, say, bladed weapons or whatever, or something really simple like a drill). This and shapeshifting are the sole purpose of the nanomachines; they can't do anything else. If an article of clothing or tool is moved too far away from her or leaves physical contact with her for too long, it dematerializes. She can also project holograms in a short radius around herself, either in the form of two-dimensional signs, or ghostly three-dimensional objects; these are always insubstantial, glowing, translucent, and obviously not real if you give them even the slightest scan, either magical or technological.
NPCs
Double-A< Named D-Tier >: A gruff Eudaemon concerned for Emily, with weaker but similar abilities.
A gruff Eudaemon who accidentally became concerned for Emily, Erebus-model AA23 has the standard Eudaemon abilities of shapeshifting and constructing tools out of nanomachines, flight, holograms, and shooting lasers; as an Erebus-model, she can examine technology to figure out how it works, though this doesn't work as well for tech which is significantly different from that of the halcyon remnant (or significantly more advanced). In contrast to Emily, Double-A is somewhat aggressive and quick to get confrontational or defensive, and she also likes terrible puns, although she hates being compared to Emily for the latter trait. Her biggest other complication is that, while she prefers not to get involved in fights, when she <em>does</em> become involved, she has a tendency to forget about or lose track of one or more enemies if she's surrounded by too many at once. She first met Emily a couple of years after their world Blossomed, and Emily helped rescue her from being possessed by ghostly digital beings called Wraiths. Due to feeling like she owes Emily twice over, Double-A has started to follow Emily around from time to time, out of concerns that the Greater Eudaemon's greater synchronization with her "self" is somehow dangerous, and about the malfunctioning Timestop Templartifact.
Complications
Weak Spot for Massive Damage: Her CPU core, the most important part of her, is where damage happens.
Her mind is stored in her CPU core, controlling every other part of herself. When she takes damage, or uses too much power at once, it places a strain on her core -- slightly moreso than it would on a regular Eudaemon, in fact, owing to a greater connection between her "self" and her body: damage doesn't just happen to her nanomachines, it happens to her. It's protected both by an energy-shield and by having several inches of shapeshifting-nanomachines wrapped around it at any given moment, but if her CPU core is damaged to a significant degree ... she can self-repair, in the space of hours or days, but she might need to reactivate her Capacitor Seals lest she damage herself with her own power, and if it takes way too much damage, she'd be lucky to remain conscious. When unconscious (as opposed to standard sleep-mode and suchlike), her nanomachines do an emergency transformation into a backpack-like "orange box", as storage for her CPU core and any damaged nanomachines while they repair themselves; its purpose is for someone else to use to extract her from an accident in the course of regular civilian activities, and won't really stop a determined enemy from destroying it and her CPU core.
How Do I Human?: She has trouble interacting with others or respecting boundaries.
Emily has spent a number of centuries relatively isolated, with no contact except for the occasional rampaging machine and other antisocial Eudaemons. As a result, she doesn't have an instinctive understanding of anything beyond the most basic social interactions, and she's a bit arrogant and self-absorbed. She isn't dumb, she's reasonably intelligent and perceptive, it's just that she's greatly lacking in common sense. She also has no concept of boundaries; there's never been any negative consequences for exploring a ruined factory, and prior to leaving her homeworld she'd never encountered anyone who wasn't unfriendly at best, so what's wrong with waltzing through an "Employees Only" door? (Homes, now, that's another matter. She understands the concept of wanting to keep "a place for yourself" just fine.)
Zero Gravitas: She's learned to love her weirdness. A little too much, in fact.
Emily figured out pretty quickly that she has difficulty dealing with others. Rather than trying to solve this, her response was to embrace it. She loves being the center of attention, and doesn't care whether the attention is positive or negative; she loves it the most when the reason for this attention is that she's strange or unconventional. This is extended to her sense of aesthetics: she might view a vicious monster as "cute", for example (though this does not extend to actual death or horror). There is a limit to this, however: she becomes genuinely embarrassed if someone tells her they don't like a nickname she's given them or the way she was talking about them.
Amoral Hero: She plays the "good guy" because it's easier, not out of moral instincts.
She is not precisely a "good person." She tries, because the consequences of engaging in outright villainy "would be a pain" in her own words, but she doesn't have an instinctive understanding of right and wrong the way other people do. Her attitude is that as long as her actions are a net positive, she's "good enough." The exception to this is that she becomes angry when people get mind-controlled or duped into following others on false pretenses, in which case, her response is likely to be ... disproportionate.
Fair Fighter to a Fault: Even when this isn't necessarily the best idea.
Years of needing to use her Capacitor Seals have left her with the general feeling, and thus the philosophy, that you shouldn't go all-out unless you really need to. If her opponent is weaker, she'll just lower her power to that of her opponent. If she's part of a group, she'll try to put herself around the average level of capability of the rest of the participants. It doesn't occur to her that she might need to tell anyone she's doing this, either. If she's ever forced by circumstances to go all out, i.e. because there would be massive negative consequences if she doesn't, it would greatly upset her, if not outright mess with her head.
Now What?: She is simultaneously rebellious, and desperate for a purpose.
Emily doesn't have "authority issues" so much as "authority subscriptions." She's willing to follow rules if it seems like it will be more fun (or at least less of a pain), but by and large, her relationship to authority is somewhere between "blankly ignoring", "unaware that it exists", and "I put up my middle finger at them". Nevertheless, she also has a deep-seated need for a purpose; when engaged in a particular enterprise or adventure, she almost invariably tries be part of a group rather than operating solo (even if she still carries an anti-authoritarian streak in the process), and she'll sometimes latch onto whoever seems to be the most "heroic" person present and "follow their lead".
Android Corpse Trauma: She is greatly disturbed by the sight of dead androids.
After an encounter with a monstrous robot which kidnapped androids and tried to use their corpses to make herself more "beautiful", Emily has discovered that if there's one thing that kills her ability to keep her cool, it's the sight of android corpses, especially ones which expose halfway-realistic musculature or skeletons. It's not enough to give her a breakdown or anything like that; she'll still capable of fighting. It's just very disturbing and distracting, in ways she can't hide at all.
