Will this be freeform? Or use a system of any kind?
Freeform, with an emphasis on realistic, rather than dramatic, roleplay.
Here is a rough draft of the setting. The chat will be set in modern day.
As for the location, the island and the city are both called Miskatonic, and it's just off the coast of Massachusetts (About twelve miles). A ferry goes back and forth between the mainland and the island twice a day; once in the morning, once in the evening.
Miskatonic is a fairly small settlement; about five thousand citizens in all. The place has, in recent years, begun to slowly die; their are few good opportunities out on the island, and many of the younger adults leave for the mainland to go to college, and never come back.
A lot of the jobs involve fishing; either being out there catching the fish yourself, or working in the plants where they are processed and canned, and the like.
The town has only one preschool, middle school, and high school to serve the educational needs of its citizens. Many of the shops out here are mom and pop stores. A Wal-Mart, and some fast food joints can be found there, too, but people tend to be ambivalent about the big corporations.
The island is home to two dozen acres of beautiful forest, with some wild life. In the warmer months, many choose to go hiking, or camping.
On the far edge of the island, away from the city, is a privately owned waste disposal site. It went in back around 2000, and stores all sorts of toxic chemicals. It is far enough away that this does not directly have an impact on the citizens, and the town is paid well by the company that owns it for its presence.
Miskatonic tends to be a gloomy place, due to the weather. Mist is not uncommon, and the wind tends to be strong and chilly, even in the warmer months. The occasional big storm will sweep through, causing some damage, but the citizens are stubborn, and always rebuild.
Miskatonic has a small, but budding, tourist industry.
Any questions, ideas, feel free to pitch them at me. I want to make this a setting everyone who plays in will enjoy, and I can't do that without feedback.
