Hello, to all my readers this is a story to hopefully fit in with Whitetigerwolf's Monsterous challenge. It is FemHarry and will with 95% probability be femslash if not it just won't have romance, also don't expect much of the harry potter world in this because there likely won't be also nothing godly that isn't greek/roman and even so mostly focusing on greek because the truth is I only finished PJO and read part of HoO never touched the stuff about egyptians and norse and what not and whatever else there is so definitely none of that hope you enjoy. Also the Authors note at bottom will get like... mildly spoilery so yeah nothing too specific honestly, its mostly going to be about the pairing.

Acacia potter was having a wonderful day.

It was the start of a new school year which means she had a new teacher, one who was new to their school, so she'd never heard the things Dudley and the other Dursley's spread around about her, wasn't like the other teachers who'd ignore what Dudley did. So for once she'd had a peaceful day at school, one where she wasn't teased or pushed or hit, one where no one did anything to her during lunch and she was able to eat in peace.

She should've known it wouldn't last.

It happened after Uncle Vernon got home. She'd been in her room, which was the cupboard under the stairs at the Dursley house. She'd recently been wondering if she'd keep fitting in there as she kept growing, though she thought it was unlikely that she would get that big she was already smaller than everyone else. At 121 cm she was about 10 cm smaller than the average height of her class and 7 cm shorter than the next shortest kid, this may not seem like much but when everyone is under 150 cm 10 of them were a lot. She was also 10 kilos below what she should be at that age too, of course this meant she was much much smaller than Dudley who she equated to a young killer whale.

She should've realized something was wrong when she heard someone stomping through the house. While Vernon and Dudley were by no means light footed, Dudley having shaken the house jumping up and down during tantrums before. However she should've noticed that these were decidedly different, not that this realization would help her a bit.

As she was wondering how big she'd get she was suddenly startled by her door flying open, a very purple-ish red faced Vernon Dursley standing there.

" Girl do you know where I've just come from?"

"W-work uncle?"

" No… I've come from the school, your teacher called me about Dudley, spouting some trash about how he and his friends were bullying you and how that sort of behavior was unacceptable. What have I told you about spreading lies like that."

" I-I didn't say anything to her sh-she just saw how Dudley was acti-" Acacia was shaking as she spoke, sitting on her bed, which was really just an old camping cot. She had been cut off by Vernon gripping her shoulder and violently pulling her up to her feet before slamming her against the doorframe, she closed her eyes and cried out in pain only opening them a few seconds later feeling blood drip down the back of her neck.

" WHAT HAVE I TOLD YOU ABOUT LYING TO ME YOU FREAK"

"P-please uncle." she groans, voice weak tears of pain streaming down her face.

" IT WASN'T ENOUGH THAT WE HAVE TO PUT UP WITH YOUR FREAKISHNESS NOW YOU GO AND SABOTAGE DUDLEY" Vernon shouts before throwing her down to the ground.

Acacia only let out a whimper and even that was cut off by the cough of blood after uncle vernon kicked her on the side she was fairly certain that she had a few broken ribs some even puncturing her lungs.

" Vernon what's going on?" Aunt Petunia calls out from the stairs above the cupboard and gasps. " Vernon you'll kill the girl someone will ask questions."

" Bah she'll live and if she doesn't we'll say she ran away" Vernon says stepping out of the cupboard and a few steps back looking up at Petunia on the stairs.

Due to this shift in his attention failed to notice the changes taking place upon his niece. He failed to see how the shadows seemed to gather towards her fallen form, or how her red hair which before was fairly tidy and reached only the top of her shoulders grew into a wild mane of hair reaching the small of her back and became pitch black, her ears turning into black furry wolf like ones and a matching tail growing from her aptly named tail bone, or her eyes turning from emerald green to an almost glowing amber red.

No, the thing Vernon Dursley ever noticed, was the pain as his neck was bitten into, and his throat all but torn out, not even lasting long enough to hear the scream of his wife.

If someone were to ask Acacia what was going through her brain when she'd killed her uncle she honestly wouldn't have been able to respond. If someone had asked her what had gone through her brain before hand she'd tell them, it started off with fear, then pain, then even more fear, fear for her life. That had all given way to anger, a level of rage which she didn't believe was humanly possible, and considering what she learned later, it might not be. Then as quickly as that rage had come it had disappeared, or perhaps she had, that's what it had felt like to her, like she moved to the backseat her place taken over by an insurmountable darkness.

She had been worried that she'd be lost in that darkness forever, she honestly had thought she died for a moment before being brought back by one thing, the taste of her uncle's blood. This shocked her back into control of herself however much she wished it hadn't. After realizing what she'd just done she could barely move. Her heart was racing, body shaking, blood pumping so fast and loudly in her ears she couldn't even hear her aunt's screams. Worst of all she found that no matter how much she wanted to she couldn't throw up. No matter how much she wanted to rid her mouth of this taste, the taste of human blood she couldn't bring herself to do anything about it.

Because she enjoyed it. Despite all wishes to the contrary she could not deny it was the best taste she'd ever experienced. This realization is what made her feel sick, what made her collapse onto her knees, and disappear, slipping without trace through the shadows.

Hello again, hope you enjoyed that or at least found it interesting enough to follow. Now for pairings I'm a bit torn on either Artemis or Thalia which makes it pretty clear she'll join the hunters because I mean, the only other option is camp and as a collective, they're kind of assholes I mean seriously they were asses to tyson and while full monster he's a cyclopes who serve olympus and work the forges and all that plus he had a half brother there and the Hephaestus cabin who were nice to him, Acacia would never survive joining there if she'd even be allowed, so yeah Hunters it is, and like I said either Thalia or Artemis, Acacia will be about 13 and a half when she joins which would be at titans curse and I really don't care about age difference with Thalia because for one thing it's like I think the same age as Percy and there are plenty of ships with them and also because compared to Artemis's age difference or the age difference between any mortal and a god its like pathetic and as immortal hunters they'll have a while to mature. The second matter is parentage, willing to take suggestions on whether her monster parent is a regular Hellhound or ol' cerberus himself, regardless to say I will not be getting into the mechanics of how that happened and her parent if a hellhound will likely never appear and if cerberus still won't play any big role, partly because he is busy with the whole guarding the underworld thing and the when he had time to well have acacia goes into those whole mechanics I will not be mentioning. Furthermore she will be getting a Stygian iron weapon and a way for her to learn at least rudimentary magic likely a spell book/ grimmoire sort of deal and her weapon will be her focci for magic as well, currently thinking scythe just because that'd be cool and what not but I am totally open for suggestions, oh they do have to be melee weapons, she'll get a bow once she joins the hunt of course.
