I should be able to post again by tonight. :)

Alright, just spitballing here, but how about: ~ Lucis has 13 moons, each corresponding to a zodiac sign. ~ There are different kinds of afterlives for different species/cultures, each with their own designated guide (Valkyrie, Dullahan, Shinigami etc.) ~ Attempts to map the Black Gale have all failed ~ Earth's moon hosts only abandoned colonies ~ There is at least one Ancient Egypt-esque lost civilization in LucisIf we're doing moons by zodiac sign, I refuse to count Ophiuchus as a 13th sign. So I like 12 moons personally. But good ideas. Also, we actually have some established ideas on how we're doing spirituality/lore/mythology in regards to your second point. Other than this, cultures and such will evolve with beliefs they find most fitting regardless, so none of it actually has to be legit to be legit if that makes sense.

Species
Dragon: dragons of Earth are as rare as other magical species, but far stronger. They take it upon themselves to defend other beings from hunters and humans who would exploit them. Overtime, they have "evolved" to take human shape, allowing them to blend in with society as necessary. They're strong and durable creatures, and (on earth) only another dragon's fangs or claws can penetrate their scales. However, the magic on Lucis is far more advanced, so there might be some weaknesses found there. They tend to live to be ten times as old as humans, so the early hundreds tend to be considered young.

Biography
Dagny was one of five hatched to a family of dragons in Sweden and probably the slowest to mature in every sense of the word. Granted, she was also the most willing to learn and optimistic about the world. The mystic community was small and she was essentially home schooled, however, and this was frustrating for the curious little dragon who wanted to explore all corners of the world. Time went by and she remained mostly isolated from the big, big world of humans. Eventually, her thirst for knowledge faded away into apathy and she grew shy in her questions and interest in the world.
Much of her personality and spunk was revived when she finally left Sweden to explore the world. Easy enough for a beast with wings sized to rival a plane. It was during this time that she really learned about the world--both the magic and technology driven--around her. She learned that creatures like her--creatures born of magic--were such a minority on Earth and they needed to be protected. Very few could contend with modern technology, but dragons like herself remained strong competitors against the evolution of human technology. Her run-ins with humans left a lot to be desired, however, and she found herself mistrusting their greed and power lust.
Then, the Black Gale appeared.
An incredible moment for both worlds, for sure, but Dagny and other dragons were hesitant to have anything to do with the phenomenon. But, time went on and the Black Gate proved dangerous not only for humans, but for other mystical creatures as well. And the second world, Lucis, proved to be swelling with magic, which spawned interest for the mystic beings of earth. Already identified as a guardian of sorts for the magical community, Dagny's personal interest grew in the Black Gate and the academies dedicated to maintaining it.
Needless to say, when she received the letter four years ago, she decided to take the school up on its offer.
Personality
Dagny's motivated and ambitious, and doesn't really do anything half-assed. Like, if you're walking, she's POWER WALKING. If you're eating dinner, she's DEVOURING DINNER. While this can make her come of as intimidating or intense, she's generally in a good, loud mood. She used to get embarrassed and quiet down, but now she's rather confrontational when she gets odd looks or whispers--though she doesn't usually mean harm.

To be decided
Fear(s)/Weakness(es)/Limit(s)
Dragons are far sighted so up close, they can't see as well. Because of her natural size and weight, Dagny is physically slower than most fighters. While it's nearly impossible to penetrate or bruise her skin, any damage to her mouth or eyes will hurt like a bitch. Magic can do harm to her, too. She's not as strong as a full fledged dragon either.
Skills/Abilities/Traits
Fire breathing, super strength, and super tanky. Her true form is compacted into her human body, making her ridiculously dense and massive despite her being average size for a person. This weight makes her extremely hard to knock of her feet. On that note, she can turn into a dragon (or rather she can turn into a human because her default form is a dragon) and change her features to match that of one (for example, growing her nails into dragon claws or scales over her skin).

Other
She tends to speak English, but her Swedish accent gets thicker the more emotional or passionate she is. She's also gay, preferring women to men ten times out of ten. Joseph Conrad is a little bitch, pass it on.

Species
Human
Class
Sniper
Weapon
Khayal: a relatively heavy double ended glaive with the capability of transforming into high caliber sniper rifle able to penetrate most armor. Since coming to the Academy, she has modified it time and time again. In her five years, she has cut its weight in half and increased its power by about a third. It's also able to transform between glaive and rifle within three seconds.

Biography
Zar was born, but barely raised in Pakistan, as she immersed her self in education in other countries after primary school thanks to her wealthy family. Maybe it was because she was born around the time the Black Gale appeared, but she had always been intensely interested in becoming a Gatekeeper. And from preschool and on, she was always attending an elite academy. Maybe it's because she's an only child or maybe she's just a really driven person, but she was always outstanding in her classes.
With the Black Gale and Lucis such a modern, exciting issue through her youth, her interest in it only grew. So, at fifteen, when she received the invitation to join the Academy, she jumped on it. And when she first arrived, the skill gap between other students...didn't scare the girl. Instead, she was inspired to work even harder so she could stand on equal footing with other students. This lead to her time at the Academy being spent on combat and tactics and on her time on Earth furthering her knowledge about technology.
Now, she's a fifth a year, ready to contribute all that she has built upon until now to the fight for peace.
Personality
Despite her resting bitch face and intimidating, boarderline-goth appearance, Zar is quite friendly upon first interaction. However, she's outspoken and will let you know when she agrees or disagrees with you. She has a sense of humor--assuming she isn't the subject--and can be surprisingly charismatic when she's passionate about something. Zar is independent but loyal and makes an effort to work with others for the greater good.

Fear(s)/Weakness(es)/Limit(s)
Well unlike all these freaks, she's just a human. Her melee skills are good, but probably her weakest point as she prefers to keep her distance in a battle. (AKA other 5th years are more than likely better at it.) And although she makes an effort, she still has trouble working others. Has trouble trusting others due to a fear of potential rejection or betrayal.
Skills/Abilities/Traits
She's particularly strong for a human woman, as she needs to be to wield her weapon at close range. She's surprisingly quick and agile, as well. There's nothing superhuman about her, however. Zar likes to keep her distance, where she can observe and plan. She doesn't have luxury of being able to run in blind, fists swinging. So, she's very methodical and cautious. Even in melee, her pole arm allows her to keep her distance as opposed to getting too close to the enemy.

Personality
Dagny holds herself to high standards and typically does a good job of meeting those standards. This can lead to her being extremely hard on herself when she messes up, and she tends to hold herself (and other dragons) responsible for the safety of other magical beings whether or not she is able to intervene. She's motivated and ambitious, and doesn't really do anything half-assed. Like, if you're walking, she's POWER WALKING. If you're eating dinner, she's DEVOURING DINNER.
