With the disappearance of much of the greenwood they used to inhabit, the satyrs were forced into the cities. Their wayward nature made them ill-suited for a life among humans and their desire to roister and rollick and cause all sorts of mayhem was simply too strong an impulse to ever be subdued. As alcohol became much easier to procure, the satyrs drank until they were all but numb to the effects of wine and other liquors. No longer able to satiate themselves with alcohol, they moved on to stronger substances, and for hundreds of years, they experimented with and abused of all sorts of drugs. Eventually, this transformed them into decrepit versions of what they once were.
Today, satyrs mostly live in small groups of which you would hardly ever see more than 3 or 4 at a time. That is, if you would ever get the chance to witness them to begin with. They stick mostly to the shadows, hiding in alleyways and other dark corners of the city. Only ever emerging from their reclusive dwellings when on a quest for drugs, alcohol, or people to torment.
They depend largely on a drug called 'Venom'; an injection based stimulant which causes intense euphoric feelings for its user at the price of burning its host from the inside out. Venom destroys the body, and rots the brain slowly when taken sporadically, but, can kill someone immediately if taken at too much of a large dosage in a single injection. This drug is responsible for making many satyrs almost feral in behavior. Luckily for them, thanks to their divine blood, almost none die from abusing of the drug, but instead proceed to fall deeper into a dark spiral towards insanity.
