@JohnSolarisOkay, the following things have been changed
(Life) Marsh's Aura:
Life blooms around her, except its not exactly the kind of life you would want to see. Passive changes happen around her, plants get thornier, bushes get ticker, dead beings deteriorate faster and venomous beings become stronger, however the true danger happens when she is actually focusing on something, her sharp nails (see the next skill) hold a myriad of bacteria, some can even predate on a person mana vessels, however these bacteria are linked to Meredith's Aura and should the farther the infected being is from her the easier it will be for the body to react and heal.
(Water) Water adaptation:
Changes in her skin and organs made her almost an amphibious creature. This ability does not give her the power to breath underwater but it does change her to be a better swimmer thanks to a slick, slimy skin and flippers on her feet and hand. Also, Her hand's nails and her teeth become sharper and stronger.
Biography:
Meredith was born in Eastern Europe and since she was young she would go fishing with her parents on the bogs near the city, however she started to like that ambient so much that she would often go there without her parents for camping and other activities. She wasn't a really social kid and that showed up in school, she was considered scary enough to not be bullied (The few kids who dared to anger her would be oddly prone to have dangerous encounters with venomous toads, wasps nests and poisonous herbs) and even so she was still annoyed by that ambient.
The talking annoyed her, the giggling annoyed her, the constant crying over the silliest scratches annoyed her, the kids who pretended to be dark and talked about death as if it was cool annoyed her, the talk about how they were all meaningless in the universe annoyed her. They knew nothing, she had seen the truth, the circle of life was a merciless and beautiful thing, it was neither cool nor sad, it was just there, and to belittle such complexity because its is smaller than some useless galaxy in the sky was offensive for her.
Around her teenager years she started to have bad grades in her school, the only topic she had interest was biology, everything else felt meaningless to her. Previously she tried to make an effort but as she got older depression started to settle into her mind, she had stared at life very closely but it truly scared her at one point, she knew she was amazing, a miracle of evolution, but she feared the nothingness that she was sure to meet one day, it was nice to think about how her body would feed a million lives but the fact her mind would be gone caused her a lot of discomfort and doubt. That was the time where she started to use some poisonous herbs from the marsh to induce hallucinations
Things didn't became better over the years, depression turned into an odd mysticism over souls and circles, she started to believe the drug induced dreams she had were visions and when life became too hard at home she left for a life of hermitage in the swamps. Her great plan was to slowly learn to live without anything human, her vision was that if she returned to a primal form with no clothes, no socialization and no humanity she would stop having an unquiet mind and thus would no longer fear death. She was slowly starting to get rid of her supplies and tools when it happened, she had the oddest and most real vision she had ever had, when it was over the world around her had changed and she had changed with it.
So, does this fixes the problems we had?
