The City state of Arkham holds a population of 3 million people some 5000 of which are practitioners of the alchemical craft. It’s boarders are closed and Isolation is strictly enforced to the point where no local is even allowed to go to the boarded without express permission from The Guild. Being a combined size of 500000 square km the country is almost entirely composed of one interconnected city with small regions of nature and Artifecias scattered throughout it. These regions are kept reasonably prestien for the usage of Alchemists of varying Guild rank’s to use as Material Gathering Points. Any member of a noble house has free access to these areas regardless of rank though it is not recommended for inexperienced Alchemists to wander into some of the areas. The Garvegian Line a massive ancient train connects the entire city and Nestled in the center of the city The Dark Tower looms rising above the clouds and reminding all in Arkham were the seat of power The Grand Alchemist resides.The streets are kept safe by The Enforcers who handle the majority of law enforcement and crime investigation. Elite teams of law enforcement known as Ravens handle crimes of a more alchemical nature or crimes that are above the expertise of common law enforcement. No law enforcement is flawless however and despite the guilds best efforts Organized Crime Families do exist making up the criminal underworld of the city.
It is known That Arkham is an ancient city and even an older country. It’s Rich History dating back easily 10000 years if not much longer but do The Great Cataclysm of the past much of its ancient history is lost. There are myths and Legends that circulate among the populace but Given the scientific nature of the guild and its alchemists myth and legend is never given much merit in the practical histories.
