The mouse man nods and gestures you to come close.  "No need to apologize, I'm always happy to have guests, especially if they are customers."   He moves about as he talks, adjusting several pieces of his equipment.  "As to what I do?  Well I'm an alchemist. I can brew potions that can make you stronger, faster, smarter.  I can craft healing potions, or potions that remove taint from your body."<br/><br/>He peers at your body and adds, "Not that you appear to be tainted by this realm yet, but you might.  In addition you might come across powerful items in your travels like the milk of a succubus, I can remove the taint from those items so that they may be consumed without adding to your own corruption.  I can make food safe for you to eat if you're worried that it's bad.  Finally I can turn items of the demon world into powerful weapons or armor.  All these things and more, for a price, if you've the gems to spend."
