Mostly the same players. The first game had the most amount, but they petered out to a stable core of four players. I have to commend them, they were really great players.
I don't have a unified setting document. A lot of it is in my head, or in my campaign notes, or in scattered .txt files, or in private messages with my players.
But I have written down blurbs and primers for my players so they know what kind of adventures to expect. Here's the first primer I wrote, and it explains the setting rather well.
