The vampiress had departed without giving a response about any preference for the flavor of the blood supply - it seemed it didn't bother her as much as he thought it might. Hm. In any case, as she left Nevin followed her to the door, locking it up behind her as she and her fox left. Once the door was locked he propped a sign on the window sill next to a candle -
Brewing. Caution. A simple caution, but one that people had long ago learned to heed. A brewing alchemist was dangerous, perhaps more than at any other point for most - during the process, the reagents they were using often took on unstable properties of their own. No, far safer just to avoid the place for a time. Nevin was glad the local clientele had accepted the fact that he only put the sign up when he was truly brewing - apparently, some of the local Alchemists would put similar signs up and leave them up at all times, making it impossible for people to know whether or not that particular shop was actively working on a potion or not. Sloppy, in his opinion. At least the Guild tried to stamp that out when they caught one of theirs doing it.
Door locked, and warning in place, Nevin turned and headed into the back of his shop. There was no handy basement for him to work in here - but there was a somewhat secluded office that he had been able to renovate into his workspace. He closed the doors behind him as he went - no point in slipping up on good practices now.
A few steps carried him to one of the cabinets in the room. A gentle toss landed the book on the table towards the back of the room, and then Nevin opened the cabinet. Red threads snaked out from beneath his clothing, weaving together into larger cables and ropes that danced in the air. Nevin pulled two large jugs from inside the cabinet as his threads heeded his will, circling around the room and picking up small pots and vials. His various burdens were deposited on the table next to the book, and Nevin rolled his shoulders.
It had been a while since he'd worked on a potion of any kind in this sort of quantity. His normal small flame and pot wouldn't work for this - no, two liters of blood and the various additives for nutrition would require his cauldron. If she had been going to consume all of this in one go, like a snake eating a large meal and then going for an extended period with no sustenance, this would have barely required any preparation at all. Dump in the additives, stir, and done.
But. This needed to last for at least a month - and Nevin hoped that two liters would be enough to sustain the vampiress for that long. So, without preservatives that would possibly ruin the precious fluid for.... Cobalt. She had never given him her name. Well, thankfully she had a rather distinctive appearance. Hm. Whatever her name was to last that long without preservatives, it would require a suave of his magic.
Crimson tendrils reached out and plucked up the jugs and poured their contents into the large cauldron. Red blood flowed out, pooling into the bottom of the cauldron, and Nevin set to work. A thick cable of threads slipped into the blood and began stirring it rhythmically, as Nevin's hands and other threads plucked various containers from the table and counters around him. Powdered plants, crushed minerals, simple splices, traces of different liquids - all were added in, the thick rope of threads stirring steadily.
As he worked, Nevin was releasing magic into the mixture through the cable. He was ensuring the blood would remain as smooth and... ingestable as straight, pure blood, despite the additions. Not only that, but the addition of his magic would keep the blood as fresh as possible for up to a month. It would have been easier if he had just added some of his own blood to the potions, but he had no idea what would happen if a vampire drank some of his blood and he didn't want to test it when he would not even be there to see the results.
Finally, the process was done. With a ladle, he separated the mixture back into two separate jugs, and put a stopper in them. Nevin brought the jugs out to the main area, and set them beneath and behind the counter, out of sight, before he walked over to unlock the door and remove the warning. That done, he returned to the counter and started doing paperwork.
The door rang and he looked up as the person announced herself. It was the vampiress, and now he finally had her name - Sivienna. He cleared his throat and nodded.
"Yes, Miss Sivienna. I've got them right over here." He lifted the earthen jugs onto the counter and tapped them. "Two liters, with nutrients added in. They'll last for approximately a month. I hope that there is enough." He rang up the transaction before raising an eyebrow to her.
"If you know of any others who have... Requirements like yours, telling them about my shop is fine. I know it can be difficult to find providers."
