"Abilities are more than just magical. Perhaps you're renowned for your strength, or for your speed, or your intellect. Or if you're a waste of space, your bitchiness, or just your straight life force. There is always some quality of an individual that can be brought to the fore and exemplified. My magic helps me know what that is. But, I can also create potions targeted to a specific person, if I need to, as you guessed. A tailor made medicine, dosed with a few drops of a person's blood, would be more effective than a general one off the counters or shelves." Nevin shrugged slightly, glossing over the barb he'd dug in there for her sake.
"I also create standard medicines and candies, as well as doing research into more esoteric and rare plants and animals for use in alchemy. I travel when I'm not actively manning this store, and my apprentice oversees the store in Stonevale when she can. There, I dealt with the issue miner's get from breathing too much rock dust in the tunnels, where their lungs have trouble getting enough oxygen into the systems. I cam here to Radasanth to force myself to develop different skills in terms of alchemy. Or rather, to hone what I had." I shrugged and looked around the store. It wasn't much, but this place was mine. Then he turned his gaze to her and raised an eyebrow.
"But then, I'm not the only alchemist here. Eteri told me you were skilled yourself - what's your focus in?" Talk with her, make nice, and keep thing from getting too tense. He would make an effort to be polite, for Eteri's sake here if for nothing else. The blue-haired cat girl really did care for her sister, and while Ayaka clearly just thought of him as another tumbleweed in her sister's life, Nevin intended to be a bit more of a permanent fixture than that. So being on at least half decent speaking terms with Ayaka was somewhat necessary. Even if she did seem to go out of her way to be crude.
There was some small talk - Ayaka had mellowed, but only a little, as they discussed Alchemy. She tried to get Nevin to share some of his private recipes but he just smiled and shook his head. In retaliation she had huffed and refused to look at him, touting how everyone else had realized how great it was that she was interested in her knowing their trade. He had simply said he already had an apprentice he was training, and that they were learning his secrets, not someone else.
