Sun and Moon - The Solace and Lunar are her deities. She has the power of both, but only one at a time. During day or under sunlight, she gains access to her Cleric spell list, but can only cast these spells. During night or under moonlight and darkness effects, she deals additional damage on attack rolls equal to her proficiency bonus. She gains access to her Warlock spell list, but can only cast these spells. (eclipsemancer lv 1)
Bless of the Tireless - She has expertise on Perception and Darkvision, and as she is one with the forces of the Sun and Moon, she can always sleep no mater what time of day it is, and she doesn't feel tired if she doesnt sleep, however, she still needs to sleep. She also gains these bonus effects while asleep: during day or under sunlight, she can immediately awake if something fails a stealth check against her passive perception; during night or under moonlight and darkness effects, she is invisible to normal and darkvision. (eclipsemancer lv 2)
Darkvision - can see in dim light within 60 feet as though it's bright light, can see in darkness as if it were dim light. can't discern color in darkness, only shades of gray (fey'ri)
Fey Ancestry - magic can't put her to sleep, and she has advantage on saving throws against being charmed (fey'ri)
Trance - doesn't need to sleep, instead meditating deeply, remaining semiconscious, for 4 hours a day. Can still have dreams, though they're more of a mental exercise than anything else. Gains the same benefits as a human with 8 hours of sleep. (fey'ri)
Elvish Blood - Can create elven magical objects as shown in the table "elven magical objects for fey'ri" and belong to prestige classes reserved for elves (fey'ri)
Elven Mask - Can shapeshift at will (free action). Will revert to her true form when she dies (fey'ri)
Winged Subrace - Can cast jump spell once at will and need to finish a long rest before she can cast it again. When reaching 3rd level (reached), she can cast feather fall once at will and needs to finish a long rest before she can cast it again. At 5th level (reached), she can cast fly once at will (same rules as above). These traits cannot be used if disguised with the Elven Mask.

Keen Senses - Proficient in the Perception skill (winged subrace)
Saving throws are constitution and wisdom (eclipsemancer)
Researcher - When you attempt to learn or recall a piece of lore, if you do not know that information, you often know where and from whom you can obtain it. Usually, this information comes from a library, scriptorium, university, or a sage or other learned person or creature. Your DM might rule that the knowledge you seek is secreted away in an almost inaccessible place, or that it simply cannot be found. (sage background)
Common 3, but an Elvish 10 - Has a +5 to charisma rolls with sun elves (she's Just Like That)
Rituals of the Sun and Moon - During day or under sunlight, whenever you cast a spell, as a bonus action you can choose to bless the target with one of these effects: 1) resistance to fire or radiant damage for 1 minute, 2) advantage on the saving throw of your choice for one minute, or 3) temporary hit points of sun. During night/moonlight/darkness effects, whenever you cast a spell, as a bonus action, you can choose to curse a target with one of these effects: 1) vulnerability to ice or necrotic damage for one minute, 2) disadvantage on the saving throw of your choice for one minute, 3) it suffers Moon Damage. The same target can't have more than one Bless or Curse at the same time. You can use this feature a number of times equal to your proficiency bonus between long rests. (eclipsemancer level 6)

Oh brother. She is uh. A little off-kilter. Persephone does her best to be liked, but it does not come naturally to her. She cannot for the life of her intuit the feelings and desires of others. She requires a mountain of context to begin to be able to guess what someone might want from her. She views socialization as transactional and rules-based, which worked fine where she grew up, but not so much in the rest of the world. The way she sees it, "This is a fun game we all play where whoever fills their role best wins, and I'm winning." Well, she WAS winning.
She has molded her personality entirely around what others want from her, especially her family and sun elf society as a whole. She doesn't really know who she is.
The only emotions she really feels/allows herself to feel are disgust, shame, pride, jealousy, and frustration, with just a sprinkle of joy every now and again when she's given external approval. Still, it's hard to feel true joy when you're not even yourself.
Persephone is vain and prideful. She is especially proud of her family and her bloodline (though less so given the whole fey'ri thing). She'd rather ignore the truth than let her pride suffer any.
At the same time as the above, she holds a deep sense of shame, both because of her secret and because she feels inadequate in general. Her family accepted nothing less than perfection, and while faking her way through seemed to be all that was necessary, they instilled in her the idea that she could never truly be good enough, could never stop trying. She constantly oscillates back and forth between feeling superior to everyone and feeling like she's worthless. Because she so desperately wants to be liked, though, she's not above using her fey'ri powers to "cheat" at it, and this does not detract from her feeling of accomplishment.
Loves winning. When she felt like she was winning her social "game," she was absolutely giddy at all times (though internally; a proper lady doesn't giggle when she gets the upper hand).
Doesn't so much have a moral compass as a moral code. Without the guidance of an overbearing and particular society, she's kind of lost on what good and evil are. To her, "good" equals "what people like," and "evil" equals "what people don't like." Imagine a big asterisk next to "people" - she only thinks certain people matter, like, at all. She will kill a bitch and upset many people if the most important people are pleased with her for it.
Genderqueer but hasn't figured that out yet. She/they vibes, perhaps even fae/faer pronouns once she's embraced her true self.
Elven wine connoisseur. Saving her last bottle of elven wine from home; all the local stuff is below her tastes. Most barkeeps (or at least anyone who's done any market research on fancy liquor) will have heard of her family, though she finds using her family name to get what she wants distasteful in the context of getting free drinks. She's not above doing that for other things, though, but she is hesitant to use her family name too much after being ousted.
tl;dr charisma 0, deception 100. incredibly questionable morals. motivated by spite and the desire to be liked. toxic as hell. has the potential to grow as a person or get like WAY WORSE

Beauty is of utmost importance to her; she was raised to be as beautiful and pristine as possible, and she looks down on those who don't pursue beauty or who do it poorly.
Power. She trusts those who are powerful and mistrusts those who are not.
Being liked is what she cares about most. All of her other pursuits are in service of this. She will do whatever it takes to be adored by the people who she has decided to care about.

She is curious to learn of her heritage, just as she is afraid to confront it.
She wishes to return to her people and have them love her. If she could do that, she would desert everything else in a heartbeat (though, unfortunately, it's unlikely that her family would take her back).
Deep down, she wants to find a new purpose, something fulfilling. She knows she can't go back to her old life, but she can't imagine finding joy in her new one. She wants to.
She doesn't know it yet, but her mission will be to learn to love herself. This will undoubtedly make her a worse person, but she deserves a little evil! As a treat!
Same as her biggest ideal, but she wants to be liked. It's all she cares about. Losing her status is crushing to her.

Godawfully out of her depth in most social situations, which is made all the worse by how new she is to not getting everything she wants.
Carries a deep sense of shame and confusion about a secret she holds.
Cannot for the life of her believe anyone is being genuine, simply because she never is.
