Given Tanith's original Bio not only has spoilers but is reallyyyyy long with her backstory that still needs to be edited and completed, and other such, I'll spare all my little details and try and simplify it but at the same time, not leave out the important parts!

(By the way, the picture I put is kinda old, I'll have to remember to do a new and improved one later)

For the most interesting stuff, I'd recommend Backstory and Trivia at the end!

Major Universes/Books Appeared In: Sea Serpent and Descendants

Full Name: Tanith Luna Mutationem
Nicknames: T (Shortened), Snake Lady (Mostly for those who don't remember her name), Little Coral (Her Avia/Grandmother), and Caeruleum (Only by Emil, her sister)
Aliases:
- The Snake Medic, Given Tanith travels a lot, some who don't know her just call her by what she is, a part Snake-medic
- Tanith Kennedy, After Pikalus uses it for her hospital files (Sea Serpent, Chapter 14- Prison Break), Tanith sometimes continues to use this, often for getting out of hospitals under the permission of 'Doctor Kennedy'
- (Spoilers)
Age: 1,103 (Around 25 for a human, being around the young adult range)
Gender: Female
Species: Dimidium Anguis, A species of my own making. Half human, half Snake magic folk who often speak Latin, and one other language for trading purposes. Friendly and unlikely to leave home. Tanith herself is the Tropical kind (Also called Palm Tails in slang terms)
Birthday: June 28th (Sign is Cancer)
Birthplace: Villa Cocoes
Sexuality: Demisexual Panromantic
Occupation:
-Traveler (Former)
-War Medic (Current)
Languages: While Tanith is multilingual, learning other languages quicker than the average person, here are the notable ones!
-Latin, First Language, Fluent in reading and writing
-English, Secondary Language, Fluent in reading and writing but lacks in most slang and often might forget a word and have to ask what the English word for it is.
-Tokozalo, As demonstrated in Sea Serpent- Portal, Tanith does know some of this race's language. Not completely fluent and does need to hear it at a slower pace but knows of it.
Religion: Though Tanith no longer is in any language, her people do have 'Spiritus' in which they believe in various spirits that control fate.

Looks: Tanith has long, blonde hair that is slightly wavy. Her eyes are blue, not particularly light or dark in color. Her body is half human and half snake, the snake part being on the bottom half. Her top human half has light tan skin, not getting a ton of sunlight from being lower depths of the ocean and she often wears a red, flowy shirt that reaching down to her torso and covers the beginning of her tail.

Her tail follows the pattern of a coral snake, having thick red and black stripes with thin yellow stripes in between them. Her tail is about three feet long and reacts to her emotions, such as flicking back and forth when happy and backing up when scared. She has an average build, if not slightly muscular.

Tanith rarely wears anything else besides just a simple T-Shirt but if she does, it'll probably be red.

Family: (Also in quotations, Tanith's short description of them in her own words!)
Mother- Clarissa- Alive
"Mom's smart... A bit too smart. Pretty stubborn too, but direct. She knows what she wants, and isn't afraid to get her hands dirty to get it."
Father- Camillus- Alive
"Dad met Mom in war, where she thought he was one of the most impress people she'd ever met. She later found out how much of a dork he was. I think that says a lot about him."
Middle Sister- Emil- Alive
"Emil... Well, she's focused for one thing. If anything gets in her way, she takes it out of her life. She's a lot like Mom but kinda... Intense. Mom knows how to charm people. Emil knows how to intimidate them."
Youngest Sister- Grazia- Alive
"Grazia has and always will be my responsibility. No matter what age, she's always got a youthful look and personality. She's kind and has a big heart. Good with people too. Even if I'm the one with the empathetic powers, she just has a sense for it."
Grandma- "Avia"- Alive
"Avia knows almost everything. I'd like to say I'm exaggerating but I'm really not! She knows what's in people's hearts and directs them in the right direction. I've followed her advice, she's never been wrong."

Weapons:
-Staff, Tanith carries around a silver staff with a snake coiling up it around. This staff is purely bonded to her, meaning no one else can use it, but also meaning, Tanith can't bond to anything else. The Staff amplifies her power, and even makes spells like her 'Calming Spell' possible.
-Red Dagger, Though used more passively- like for cutting things up- than combat, Tanith might have this on her every once in a while.
-M9, A simple gun that Tanith stole from Pikalus' lab during the invasion. She hasn't given it back. She doesn't intend to. She doesn't have the best aim so she prefers to use it at close range, if needed at all. More a last choice if anything.

Hobbies:
--Knitting, Tanith uses knitting mostly as a stress reliever. And seems to make scarfs the most. The more scarfs made, the more stress.
--Potion/Medicine Making, Tanith quite likes potion making and does it in her free time. However, she's not always the best at it, given more than once she needs to buy new glass bottles because the others broke when her concoction exploded. She'll also sometimes try and make her own, but 9/10 times ends in disaster, or just not working at all. She will sell some of her successful ones, her 'Healing Tea' which works great for the throat is one example. (But later gets in a bit of trouble when she learns you need a licence to sell)
--Baking, In her own words 'It's like Potion making, but with food'.
--Gardening, Tanith likes to grow her own ingredients 

Magic:
--Healing, Tanith's main and strongest type of magic, easily usable without much help. It's simple, a stream of golden/orangey magic, fluid, think like water or syrup, that heals whatever it touches. The more serious the wound, the harder it is to heal. She can't heal things like broken bones or bad bruising right away, but over the course of a few days, it's possible. The magic comes from her hands.
--Force Fields, A secondary power, and harder for Tanith to use but still possible without her staff. It's a blue dome or bubble that surrounds what's around her. She can make it fairly big, but at the expense of using more energy. The Force Field can take quite a bit of damage if she's at full power, but the less power she has, the less likely it is to hold up. When it breaks, Tanith can often feel pain from it, getting a backlash.
--Emotional Spells (Mainly 'Calming Spell), Tanith has an ability to make people feel a certain emotion, often calm, by in return, taking their emotions for herself. Tanith has been unable to use this without the aid of her staff. The spell goes out a mile radius on average, and affects anything with feelings. Tanith will gain their emotions and feelings in return, and while a useful spell, not only does it cost a lot of energy, it also has terrible consequences if Tanith can't handle the emotions she takes...
--Selective Empathy or "Bonding", Selective Empathy means that when Tanith gains a strong 'Bond' with someone, she gains the ability to read their emotions, starting out small at the start of the bond with only extreme emotions, and getting stronger if she grows closer with them. While useful, it goes both ways, meaning at some point in the bond, they will start to feel Tanith's emotions too. Bonds can fade if the relationship fades, but physical distance doesn't matter.
--Conscience, Her last power is her 'Conscience'. A being in her head made for helping her deal with empathy, given she doesn't just have her own emotions, but someone else's too. Conscience's are always directly the opposite of whoever's head they are in, and common for different types of Empaths, meaning the stronger the Empath, the stronger the Conscience needed. (There are some cases were the Conscience can even take over the body if needed) Tanith's however, is only Selective Empathy, so her Conscience, who she's named 'Cece', has limited abilities.
All of Tanith's magic (Outside of Selective Empathy and most of her Conscience's abilities) take up energy. The more energy used, the more tired she gets until she passes out once she's used her limit. She can't die from using too much magic, but passing out too much does have a negative affect on the body. Her energy comes from regularly needed things, food, sleep, regulating a healthy lifestyle, etc. meaning the healthier the body, the more magic that can be used. 

Fears: 
--All her friends dying and being alone
--Birds of prey
--Heights
--Riding in most vehicles 
--One day learning her family died and she never got to say goodbye in person

Personality: (Probably gonna write a whole essay later but for now, I'll just list the basics)
--Friendly (Shown in interactions with many in Sea Serpent)
--Sympathetic/Empathetic (Shown through 'Feels Jams')
--Devoted (Shown through her efforts not to betray neither Cody nor KrakenKid)
--Curious (Shown through her general interests about culture in Atlantis)
--Stubborn (Shown many times, especially in refusing to choose a side)
--Impulsive (Shown so much. Like I can't even count how many times she does something without thinking)
--Avoids Her Problems (Shown through 'Insomnia' avoiding sleeping instead of dealing with it)
--Secretive (Shown through her keeping her 'Bonding' a secret, as well as her tunnels)

Likes: 
--Other/New Cultures, Tanith is pretty eager to learn how other societies work, what they do, etc.
--Any Type Of Food, Tanith loves just about anything and will eat it, having a pretty diverse pallet
--Crystals, Tanith has an odd facination with them, given they were currency back home and it reminds her of home in a good way
Dislikes:
--Vehicles, Tanith gets motion sickness easily while on nearly any type of vehicle, so if she can avoid it, she will. Not to mention they're confining to her
--Spying, Tanith really hates spying or having to do any spywork. She can't seem to recall why...
--Mistranslation, Tanith hates how jumbled things get once they're translated through languages, and often learns languages just out of spite for how much she hates it so she won't have to deal with it at all. She can and will go on a rant about this at nearly any given time.

Motivations: For a long time, Tanith only wanted to see the world. Then, after several centuries, she grew tired, and only wanted to find work for her abilities. After a particular incident, she wanted to settle down and feel like she doesn't have to rely on war just to feel whole. A lot of Sea Serpent is her healing process.

Notable Characters Relating To Her: (Outside of the main gang)
--Bartholomew, Her neighbor who has a strange relationship with her, given its that they literally scream at each other every week. Though Bartholomew is not a bad guy, being intelligent and polite, Tanith hates how 'Cowardice' he can be when in his own eyes 'He just can't do anything'.  Tanith to him is simply too 'Ready to jump into a fight and looks for one' which ticks him off. It's a love-hate relationship, where they buttheads a lot, but also would 100% save their life in exchange for their own if needed. Their relationship started when Tanith wouldn't give the library the 'History of Atlantis' book back when Bartholomew wanted to check it out, he tracked her down only to find out she was his neighbor, and they got into an argument there.
--Larry, Her pet 'Luggage' or Mimic. He's a happy guy who acts as a stress reliever and helpful companion, able to carry things around for her. Larry, shown in 'Larry's Big Adventure' is shown to have an upbeat attitude and loyalty to Tanith. Tanith returns the love and cares a lot for her little friend.

Backstory: 
(Since her backstory is pretty long and I still need to write more detail into it, not to mention spoilers, I'll just leave little notes!)
--Tanith is the oldest child of her family by two human years (And a lot of her people's years) and was expected to take over her father's trading business when she grew older. Tanith didn't mind this given she liked trading (Mainly the social aspect of it)

-Tanith and her Grandmother are the only two recent people in her bloodline with a primary magic ability that's passive. (Meaning it's not for combat)

--Certain things happened with her family that made Tanith wanted to leave, and eventually, did, running away just before she became an adult. She left a note, but the only person who she talked to before leaving was Grazia

--(Maybe this should be in Trvia, but a good song representing Tanith and her Family, mostly after she left, is 'Other Side Of Paradise' By Glass Animals)

https://youtu.be/WBY9yag6mNs

--Tanith originally didn't have a plan when she left, but passed through a town in war and offered her healing abilities to help in exchange for shelter and food. Finding how helpful her powers were, she continued after the war ended

--Tanith traveled to hundreds of towns, some with successful wars, and some with devastating ones, each varying in length

--Tanith has at some point, taken up spy work. It didn't go well

--Tanith, at some point, had a best friend named Kenji, a nervous kid who was a brilliant tactician. However, due to mind control, Tanith was forced to kill him, which devastated her and damaged her relationship with Cece

--Tanith has had a lot of different roles in war, and while War Doctor was her biggest, she has been in positions of combat, and leadership before. (Though she prefers being a Doctor)

Trivia: (Just fun stuff!)

--Tanith, despite being part coral snake, is not immune to the poison of a coral snake

--A good theme song for Tanith I've found so far is 'Lights' By Ellie Goulding

https://youtu.be/iaJ4wzDO5fA

--In her opinion, English is the hardest language to learn given all the rules, slang words, etc.

*******************

Okay, this is what I have for now! I might edit it later if I remember something, or want to add something in, I'll update it, but for now, enjoy!

If you notice I'm missing anything or just want to ask me a question, please tell me! I don't bite! Heaven (And Ice) knows how much I love talking about my characters.

Anyways, I hope you guys liked this! Be sure to comment if you have questions or just noticed something, etc. I figured Tanith would be a good OC to start out with, given she's my main and I include her in a lot of things, so anyone who doesn't know her can find out more here. That's it! I'll post more character bios as soon as I can! Farewell!
