Potions and Pills sold in auctions were a common occurrence. One of the reasons for this and their high demand was how most alchemists hoarded their finished concoctions for auctions and only sold up to good quality potions out to the masses.
The world of alchemy was a stage for power dynamics. Rogue alchemists, some of whom were hired by clans lacking their own alchemists, found themselves in a delicate position. Some demanded so much that the clans resorted to threats and suppression, while even those who asked for reasonable compensation were not immune to implication.
