Alchemical Brothers Remix
Alchemical Brothers Remix is a spinoff shop owned by Digby and Sasha, which specializes in blends, capsules, and implants, located across The Stone Road from Alaster Compound, in the block just east of The Free Market. At Remix, the brothers can produce customized items by special order. They can put any compound in the form of a capsule or compartment that attaches to a weapon, shield, or armor (or they can build such a compartment for an ordinary item, like a pair of boots or a quiver); they can produce blends, combining up to three compounds in one solution that can be applied with a single action; and finally, they can make surgical Implants designed to work with specific compounds. The classic example is a hollow false tooth, but there are plenty of other options you might think of. Expect to pay shockingly high prices for such service. The brothers produce their goods at a workshop located near Remix on the same block.
What Remix does has never been illegal, and is not considered gray-market, but their technology is relatively new and some adventurers displaying such things, especially implants, might face social disapproval.
