I've started to expand this a bit, and I need to ask: Should we describe the characters in a primarily "in-universe biography" sort of way ? That's the sort of impression I got from reading the already available entries, and honestly, I'm in support of it. So far, I've tried my best to adhere to the established template (as it's really good), but e.g. in the case of Terry, I just didn't know much about him, so I had to (somewhat un-immersively) write down that he's the fence of the anonymous thief from this and that series of FMs.
P.S. I hope you like that I've decided to include not only the FMs the characters are linked to, but who their primary creators were. Hopefully, this will prevent any future misunderstandings between the original authors and anyone who would want to drop a mention of their existing characters in an unrelated FM.
