>Exhale though nose. Don't forget, Nazrin, you still have to find that damned flower before either of these liquids will be of any use to you. No matter who you get to make it. And getting mad at the professor here isn't going to make your task any easier.
>"Nothing, really. Just had an unpleasant memory cross my mind. This job's been.... A rougher ride than I'd have liked. And it isn't over yet. Whoever I find that can make this stuff, it won't do me any good if I can't find that flower."
>"But, first things first."
>"These mixtures, the vigor and the water. Do they... expire, over time? Lose their effectiveness? Say, I get them made, and then have to leave town to find the plant. Will I have to worry about the liquids becoming inert?"
>You take a calming breath and try to collect yourself. The professor offers you a sympathetic, if slightly muddled smile as you make veiled reference to your situation.
>"If you, perhaps, were gone for several months, this might be true," she replies. "Yes, certainly over
some length of time, this would happen. But not a brief one, no. For some mixtures, this would of course be otherwise, but not for these; at least one half a year should I expect the vigor to retain nearly all the potency with which it was brewed - assuming, of course, it was not stored and handled with wanton impropriety. Yes, yes, this goes without saying - not that I would assume anyone of skill to make it would err in such a fashion barring unlikely accident. Aqua veritatis is another matter, of course - and simpler, I should say! While the name itself is long dated and techniques no longer quite identical, it is in essence and function the very historic mirror of purified and activated water - the base for a great many things beyond this recipe of yours, yes. Oh, many indeed. Any alchemist at all should have this in as great or small a quantity as they ever should require.
