So, yea. Welcome to Arkham, MA, home of SHADE. I will probably add more to this as mood/inspiration strike me, but this is what I have so far.

[hider=Arkham, MA]
Arkham, MA is the location of the homebase of SHADE, and formerly of the BPRD. Arkham has long been a hotbed of extradimensional and paranormal activity. The former home of Miskatonic University before it was closed due to a multitude of unexplained deaths, the town quickly became a ghost town without the financial support of the college. 

In the 70s, Professor Broom and the still young BPRD purchased the land that contained the small town. They moved in and purged the area of its dark tendencies and began to build a town where they and their paranormal agents could live happily.

Miskatonic already had a vast occult library, possibly the biggest in the world before the arrival of the BPRD. After the Bureau took over, however, Broom curated the library to legendary status. Every possible piece of occult knowledge was stored somewhere in the vast halls of Miskatonic’s library. Abe Sapien was now the curator, always adding more information to the collection when it was discovered. 

The town of Arkham was now a haven for peaceful paranormal denizens. As such, it is possibly the weirdest community on the planet. Monsters, ghosts, demons, and unimaginable creatures all called Arkham home, and they all made it unique. Human SHADE agents often find the density of paranormal residents the most jarring thing with their new assignment.

[b]The Hanged Man:[/b] The town’s local watering hole. The Hanged Man is popular with paranormal and human customers alike, as is the establishment’s owner Igor, Doctor Frankenstein’s assistant granted unnatural long life through mysterious means. Igor is a wealth of knowledge in the magical world, though he never gives it out for free.

[b]Hangman’s Hill Cemetary:[/b] Populated by less than respectable group of spirits, including the paranormal thief that calls himself Gentleman Ghost, now bound to the location by Hellboy and his team.

[b]Arkham Tunnels:[/b] A labyrinthine space that runs underneath the entirety of the town, the Arkham Tunnels have never been fully mapped outside of the small percentage that are located below the University. Indeed, it seems impossible to do so, as if they are not continually inhabited they will change without warning.[/hider]
