In his 350 years, he had thought he had seen it all. Vesemir the unofficial head Witcher had spent years traipsing up, and down the country, he knew every path and detail of any town worth knowing to a Witcher. However, in his lifetime he did not foresee having to deal with a Witcher's mate. Barmin, his master had glossed over it in training, dismissing the idea of it being any use. In his training, he and other fledgeling Witchers had become intrigued with the concept, but the master had been dismissive enough to toss them a copy of The Witcher- A History. With a whole chapter dedicated to the Witcher's Mate. Being privileged enough to witness the building of the Witcher home he knew every book placed in the library and this battered copy preserved the only mentions of soulbonds in the entire Witcher section of the library. Barmin had mentioned that it was a Witcher's Curse to be bound to another who would wither and die or who would face dying of a broken heart as the life of a Witcher was a dangerous one before placing the book back on the shelf where it gathered dust for the past 300 years. Till now that was.

Making his way up the gritty staircase, books wedged underneath his arms, he let the soft glow of the candlestick light his way from the archive and through the winding halls. Mermaid literature held little room in the main library; Witchers had no dealing with Merfolk for 400 years, he himself only met two. The first was a stunning female, long green hair and pale olive skin, a tail of metallic blue scales, pulling the fresh Witcher from a stormy sea when drowners pinned him down in the murky depth. She had all the makings of the predator, savage and vicious yet in the cave which she dragged him, she had all the tenderness of a maiden. She was inquisitive and powerful, and to the newly made Witcher, she was direct in her wants, spending the night and day making very extensive use of his body. A smile stretched across his feature, and he remembers the dalliance of his youth. The other had been a Trition, the male of the species, while not a beautiful as the female he had been majestic in his airs. He had been just as predatory as the female but seemed to lack in power of the female, it did not have the sharp barbs of teeth, or the ability to walk on earth demanded help to free a water sprite from a tree curse. If indeed the Adva girl was a mermaid it would cause a lot of difficulties. Mermaids where predators plain and simple, with very complex social structures and even more complicated mating rituals, one that they kept closely guarded. This was going to be near impossible. Witcher bonding was going to be difficult enough to get their heads around it didn't really need the extra stress of figuring how a mermaid bonded. He envisaged many nights slaving over a manuscript.

The library fire is dying. The low flame dominated the dwindling wood giving the room a soft light. He had, on being regaled with all the details excused himself to the archives, Barmin having moved all the Merfolk down there to add a room to the main collection. It had taken the best part of the afternoon to weedle through the mass of papers and books that had chaotically thrown into to achieve with no accord. Dropping the various scrolls and manuscripts, he settled himself into his leather-bound seat and placed the candlestick back in its holder—the soft flare of flame illuminating a slim figure perched on the window ledge.

'Dove, I thought you would be in bed.'

'Not sleepy…been an eventful day.' Ciri rolled her shoulder, standing.

Moving from her perch, she fed the fire three thick blocks of wood, watching as the room was lit up with the roaring orange flame. The food she had gathered of dried meat, cheese and wine still sat untouched, Jaskier had tried to tempt Adva with the cheese and wine to no avail. Picking up the jug, she poured two generous helpings into the spare goblets and sat opposite the master Witcher.

'I don't think I would be able to sleep if I had seen Geralt finally put it to Yennefer. I would have properly celebrated so hard I would be drunk for a fortnight.' The older man laughed picking up his goblet and throw back his contents, red droplets staining his white beard pink. 'It would be Geralt that got mixed up with a soulmate who had to be a mermaid. He can't live simply, even as…Has someone fixed the wall.' Vesemir gawped at the wall by the window. The peeling stone wall had been replastered and the drafted that has previously whistled through the library on a cold night was no more. He had meant to repair it for the last fortnight, but the north-west staircase was in need of refurbishing, the barn needed to be mended, three chimneys needed sweeping and renovating and the long list of other restorations.

'Adva and she reputtied the windows.' the answer was tense and dry as she brought her cup to her lips and took a sip of the strong liquid.

'She's been her ten hours, and she replastered a wall and fixed a window? At least Geralt has the brains to pick a useful mate; I wonder if she does roofing.' Vesemir gruffed, filling his goblet and downing it once again.

Ciri could feel annoyance rise within her, Vesemir was always dismissive and so distant from his emotions he couldn't understand her concern. Since arriving, Adva had used the plaster in the hallway, despite their protest she spent most of the day fixing the wall and cleaning, Jaskier had tried to pull her away, but she looked near tears and battered their concerns away. Both Jaskier and Ciri sank back and watched Adva flit around the room, dusting, mopping and polishing. Ciri had never seen the library look so clean. In the space of ten hours, she had fixed the library and cleaned three full rooms before her eyelids began to droop, and Jaskier scooped her away before she could protest and tucked her tightly into a bed in one of the many rooms while Ciri searched through many garments that had cluttered up closets and chests from long forgot herbalists and Witchers that had come and gone to replace her outfit.

'Vesemir! I am worried about Adva; a person doesn't start repairing buildings when they learn that they are a Mermaid and a Soulmate.'

'And you know the extensive guide on how someone needs to react when they discover they are a Mermaid or a soulmate, was hardly worth me spending all day in the archives with such an expert already here.' Vesemire scoffed, his eyes glancing against the bundle he had gathered with some concern. The few books that he found would have little in them to help with their… unique situation.

'That not what I meant.' the young woman sulked, pushing her bottom lip out as far as it could go.

'Do you remember when you discovered your bloodline? It took us three weeks to stop you hacking the dummy to bits. People cope with things differently. If I had to meet Yennefer again, I probably devote myself to fixing the whole castle. You care a lot about Adva, don't ya? Empathy is the downfall of a Witcher.' Vesemire scolded. He didn't know how many time he had tried to drum that into her and Geralt.

'I…I do I see a lot of myself in her. Alone and confused, betrayed and powerful but scared about it.' Ciri sighed.

It hurt to admit; it was traumatic. The early years of her life had been so lovely, but the last decade, wave after wave of people had tried to claim her for themselves. Kings seeking power, Witches seeking power, Cults seeking power. They were all the same, trying to imprisoner, impregnate or kill her. It left her feeling insecure and uncertain; she had been betrayed so many time she had lost count. That unlimited power made her a target for every crazed group that emerged from the shadows, but it also made her scared, the power within her had a fine line between chaos and control, and with that enormous pressure to remain in control. Her deepest fear was herself, and what she could do or become, she sensed that same fear in Adva.

'You have only just met her, don't get too attached. Yennefer will find a way to get rid of her if not that she'll turn into a she-daemon knowing Geralt's taste in women.' Vesemir scoffed dryly.

Geralt was the son he had never had, but his taste in a woman was shocking, there had been that redhead succubus who tried to eat him. The doomed princess in the tower, Renfri. Three herbalists, Triss and Yennefer. He should just stick to a whore like everyone else, it would save a lot of time and effort, and the damage Kaer Morhan would be minimal, the amount of time Yennefer had destroyed something because of a petty argument was unbelievable. Ciri stood abruptly and started to pace.

'Dove, what troubles you?'

'I…Yennefer has been….I dunno. She has been difficult…'

'Yennefer difficult? Never?' The laughed trickled from the witcher lips.

'Before they…parted. Yennefer did something….horrid and tried to get Geralt to finish it… he refused, and Yennefer was vicious, and then the spell broke and….'

'Went batshit?'

'Batshit is an understatement…. I thought Geralt was wrong… that he should have but I dunno; I was so angry I was blinded.' Ciri winced at her confession.

For the most part, she never admitted when she was wrong; she was too stubborn for that; her pride would not allow her the humiliation of accepting it. But there were times, time like these when things became a cluster fuck that she could admit it. Her love for her mother figure, her nurturer and teacher had blinded her to the sheer despicable nature of Yennefer plan, so much so it had made her hate Geralt. But with every passing day, she realised how stupid she had been. Looking back made her wince with shame as she recalled all the unpleasant thoughts that went through her mind and the things she said. Ciri felt ashamed of herself, more so now she was in the Witcher's Fortress where the memories of their relationship[ resurfaced, all the times Geralt had protected her from the violent tongue lashing of Vesemir for wondering off and training on her own. The times when he gave her a silent hug because he knew what she needed.

'Don't blame yourself, Yennefer has a knack for playing on one's emotions.' The master witcher soothed in his gruff voice.

Looking up, she felt herself smiling. For all his stubborn grumpiness Vesemir was the kindly grandfather figure she needed. The bias spectator, guiding her through Geralt and Yennefer many, many arguments with a scoff and an eye roll.

'I worry about what she will do to Adva. She already seems resigned to being cast aside, and Yennefer will play on that.'

The confession was not something she needed to say out loud; all of them were worried about what Yennefer would do; even Adva could sense it. Yennefer was capable of being truly malicious especial again those who had wronged her.

'Maybe that is for the best. A Witcher's life is one fought with danger having a soul mate would be even more so.'

'You should have seen the way Geralt was with her Vesemir. The way he looked at her was…' Ciri paused for a moment in thought 'it was worshipping…I don't even know how to describe it and when she flinched away from him, I thought he could break down. When she went through the portal, I thought he was going to roar in after her. I love Yennefer, I always will, nothing and no one will change that, but at the minute I don't even what to be near her.'

A dull pain began to throb in the corner of his left eye; there was not enough ale and wine in the whole of the castle to get him through the next couple of weeks. Damn Geralt. First, he had brought Yennefer, who destroyed every room she stayed in and threw furniture carved by their Witcher founders out the window. The elder had lost count of how many times in the past decade, Geralt had found himself at the end of a difficult situation. And this situation was the worse; soulmates were messy, and for Witcher, mates were rare and unpredictable. Geralt would be a muscle-bound mess of raging hormones, worse than when he first mutated and with Yennefer roaming around, lurking in every corner, he could feel the annoyance and irritation begin to build.

'It will work out, for better or worse. But from what I know about soul bond, they are very powerful, and it would take more then Yennefer to do that….besides if she is that good at repairs, we need to keep her around.'

If he survived this, it would be a miracle.

Kaer Mohen was beyond anything that she had ever believed. Nestled in the middle of a vast valley, built into a mighty mountain, the almighty structure was awe-inspiring. Surrounded in greenery and limpid pools as far as the eyes could see, it was the most beautiful thing she had ever seen in her life. Inside did not disappoint; it was elegant, chequered marble flooring, latticed woodwork, majestically carved furniture, and rugs that while worn and dusty were exquisite. However, it was sure that the castle had seen better days, gaping holes in the roof leaked into the rooms letting in the local wildlife. Plaster was coming off the wall in large chunks, and a sharp draft came whistling through the castle. Still, it the most amazing place that she had ever seen. The library included. The vast collection of books held in sturdy mahogany shelved held behind thick sheets of glass, it was an extensive collection, most in languish she had never seen before, and the desire to pull each one out and read was overwhelming. The library seemed sadly empty just one large table and one comfy chair perched in the middle, books and quills surrounding the work area.

Vesemir seemed to be making the most of her, giving her a list of chores in the morning and then after their midday meal they would group together and spend the rest of the afternoon and evening in the library. In all honestly, that was fine with her, she didn't want to think about soulbond or Geralt. A sickness bubbled in the pit of her stomach. Waking up in the bed in a musty room brought back that only the day before she woke in the warmth of the Witcher. At least the chore distracted her from the churn of emotion that built inside of her and the anxiety that came with letting her mind wander.

'How can you read this.' Ciri slipped down next to the women who was engrossed in a book that contained mostly scribbled lines and dots. Just looking at the page was enough to give the former princess a headache.

'Lunch' Vesemir called slamming what could only be loosely described as a strew on the table. Four clay bowl slide into the various place, as they stared down at the brown slop. 'That is my famous stew.'

The elder Witcher glared at the bard who grimaced at the pot in front of him. The mixture was brown and gritty, whatever meat was unrecognisable, the smell of a mixture of fermented broth and fried meat, it was not unpleasant, but it was not particularly appetising especially with strange unknown bits floating on the top. Jaskier twisted his face in disgust as he poked at it with his wooden spoon.

'Famous because it kills anyone who eats it?' Jaskier question letting the food slide off his spoon with a spatter.

Vesemir stared daggers at the bard as he is inhaling another spoonful of stew, most of it coating his beard.

'Don't you have any more books on Merfolk Vesemir?' Ciri asked, leafing through the pile of red books scattered over the bench.

'Mermaid isn't the sort of thing Witchers deal with.'

'But aren't they supernatural creature.' Jaskier retorted his right eyebrow inching up his forehead.

'Aye, bard they are but never given us cause. Merfolk sticks to deep water and out the way of humans and creature alike. Humans have tried to wage war on them in the early days, but it futile. You aren't ever gonna win against a creature that can sink whole fleets of ships in one go.' Another heaping spoonful of stew smeared across his mouth. 'Time from the time they appear near land but never bother anyone; it does not like they would abandon one of their pod on land…especially a child. I will have enough look in the archive but the literature of the Merfolk in rare. Not many have ever got close enough. I know a while back Geralt helped some duke marry Sh'eenaz, a mermaid, but she became sad, and the couple went back to the sea kingdom.'

'So we have no idea about anything.' Ciri spoke, slowly eyes resting on the deflated other woman.

'You are more than welcome to search down in the archive, but most merfolk literature is hoarded by private collectors.'

'So we don't know anything.' Ciri bite out and throw a thick book across the room, pages fluttering across the marble floor.

Jaskier reached a hand across and took Adva's giving her a reassuring squeeze. The brown-haired woman closed the book, shoulder sagging.

'Adva If you promise to cook from now on I will go in the archives myself and battle the army of spiders in search of anything else.'

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Vesemir brought down the axe forcefully as he broke down the log and tossed it into the giant pile of firewood. From his place on the verge, he watched Adva.

Though, not the most skilful and hone in her technique Adva was accomplished. For a simple kitchen, she had a strong stance which made it hard for Ciri to break through her defence. There was no obvious contest between the two, Ciri was the more skilled and her magic more adaptive, there had been several points in which his young ward had the upper hand, but Adva managed to put on the defence, which she played well. The master Witcher didn't see that predatory creature that he had met in his experience, just a determined young woman, strong and sweet. He found it hard to believe that she could be a mermaid. Her ability with water being the only real characteristic that they shared. There was no killer insisted, no savage passion within her, no flailing tail or hissing fangs, just a scared little girl that he now had to keep safe.

Slamming the axe down Vesemir took himself to the side to watch the pair closely. Ciri seemed to tire of being pushed back, stepped up her attack by using her blink power, teleporting her way around her. The gruff Witcher couldn't help but smile, the little girl who would sneak off to practice on her own was no a skilled warrior. Adva's movement became panicked and jilted as she dodged the attack, frustration ebbing in her every movement. Collecting his roofing tools, he made his way across the stall and once against back to the field to collect the ladder. This time Ciri seemed to be on the back foot. Adva's attacks were precise and direct, one after the other. A water blast threw the young Witcher off her footing, causing her to stumble back, and whip of water then appeared out of nowhere lashing itself across her side and wrapped itself around her wrist slamming her into the dirt.

Vesemir stilled, his body is tensed his eye trained on the pair, grabbing for the axe he embedded in the tree stump. He saw it, the killer instancing, the way her eyes shone that little bit brighter. Ciri recovered well, shifting her body to the left in a blur of blue light escape the confines of the water vines before rolling up on her feet and brushing the dust off.

Adva blinked, several times swallowing heavily as she took a step back as she felt the adrenaline still racing through her vein.

'Good attack. Never really seen anything like that.' Ciri smiled, standing to her full height. 'Next time I won't go so easy on you. I better go see how Jaskier is doing. The spiders have properly cornered him in archives. We will pick this up again tomorrow…but you are going down' Ciri smirked, nodding at Vesesir before ascending the step of the balcony.

'I see Ciri found you some clothing, more practical for doing maintenance. You can help me patch up the roof, get the tar and meet m by the ladder.'

Looking down, she pulled at the outfit she had been given from a large box of items left by the various people that passed through. The bottoms were a pair of duelling trousers made from a shammy leather material, making them soft and stretchy, that held her tight across the arse and allowed for free movement. They were at least 50 years old but kept pristine by the mothballs packed in the trunk of clothing. The deep red material suited her and at least didn't show the dirt from the unkept castle. The top was an oversized tunic that fell to mid-thigh; it was thick enough to keep the chill that had started to cling in the air. A cracked old belt clinched tightly around her waist to keep the oversized garments from slipping off her body completely.

Pushing her way up the steep bank to the courtyard, Adva pulled the bubbling tar from its fire. The courtyard held the shed and the stables it was up at the top of a sharp incline; it leads all the way round to the training grounds which Ciri had been handing her ass to her for the best part of the day, a sense of pride swelled within her as she laid the foul-smelling tar into a bucket. She had managed to keep upright and had a few good hits, she was improving, and her powers had developed in the passing weeks with Triss. Training with Ciri proved that.

When the bucket was full, tentatively she pulled it up the ladder on top of what she thought was a storage shed beside the kitchen. Vesemir was already hard at work, hammering in think sleet slate into the missing patches. Wordlessly, the master witcher tossed her a tarring brush, a thin stick with a rag attached to it and nodded toward the slates. Between the old tiles was a thick layer of tar, filling any minute gaps in which the water to seep through and flood the room beneath. Adva swilled the brush into the thick liquid and plastered around the edges of the shingles.

The height was not her favourite, the mere thought of going any higher made her head spin. They worked in silence for the best part of an hour, as soon as he finished one, she would swoop in and slather the thick goop on the slabs. It was clear to see where Geralt got his mannerisms, the way they both puckered their brow when they were concentrating. The way their eyes shifted as they worked, head shifting at every noise. These features were not different that Geralt could not pass for his son, but Adva had made a deep study of Geralt, his features where sharper, more defined. Both men had strong physic, after years of training and monster hunting, but Geralt's frame seemed bulkier, shoulders broader and arms solid with muscle.

A deep wave of shame consumed her. She had promised herself she wouldn't think of him, but he crept into her mind. A melancholy fell over her, it was a numbness, at gnawed at her core.

'Next is the west staircase, I will teach you how to tack and shave down the boards.' Vesemir grunted as he threw the hammer into the dirt as he made his way down the ladder. Holding out his hand to help Adva down, grabbing the bucket and brush and tossing it to the side.

Adva nodded, thankful for something to do.

'Never thought a little girl would be much good a roofing you are a strange little thing.'

Adva laughed awkwardly, wiping her hands on her piny. 'You know what brothel is like, all hand on deck. I cooked, cleaned, mediated, fix roofs, walls, beds.'

'Not much of a life for a little girl.' Vesemir stared down at her; it was an uncomfortable gaze, that pierced through her.

The master witcher looked at her, his medallion didn't vibrate, but there was a warmth to it, just enough to heat the skin beneath the wolfs head. He wasn't sure that she was a Mermaid, but there was something. Something strange. Something different that he could put his finger on. But now she looked like a scared little girl, a girl being dragged from one bad situation to the next. Tough and hard-working but most of all, frighten of that power within her. It bubbled under the surface, threatening to rear its head.

'Last time I check I was a woman…well, Mermaid.' Adva shot him a steely determined look. He wasn't sure what she was determined about, but it made him give out a snort, it reminded him of Ciri when she first stumbled into his home.

'Well, Mermaid…we better get back. I think Jaskier is dying for more of my cooking.' The older man gave her a small smile as he guided them through the courtyard.

For once, he was as near as excited as a Witcher could be to see Yennefer again, as he could tell that sweet little maid was going to give her a run for her money. A deep smirk set into his features, if he had anything to do with it, Yennefer would definitely have a run for her money.

Hi everyone- Thank you for being patient. I am currently working in a school and it is exhausting so when I get home all I literally do is just plan and sleep. I am hoping this weekend to bash out the next chapter but with everything the way it is I am not sure I will have the time. But I will try! Please let me know what you think :) Comments are love and I need some love right now!
