I am trying to write up a little summary (or a large one, considering there are 192 posts) and a guide on which poster's characters you should read if you really want to dive into the IC from the beginning. I would say, if you want to read the IC, I would focus on NMS's, mine, and Raptor-man's characters. Some other characters are also important, but I will go more in depth later.

Edit: I just think it is important to allow easy access to what has happened in the IC to new players so that they know the background of the characters. I don't expect new players to read all the IC. That's quite a read in itself.
