Alchemy Poison Lab (Patreon)

This Chemistry Lab is well buried within a mountain cave. The scientist that runs it make all kind of experiments and this time he extracted bile from Mountain Trolls and managed to synthetize it to create a powerful acid that can dissolve corpses. He's made a business out of it, deleting cadavers for both the local authorities to create potions of your "Beloved Deceased" and also, and more profitable, for the kingpins that want to erase remains of assassinations.
