The Eastern Isles System is a homebrew fantasy roleplaying rules system that I developed for my Eastern Isles / Laratoa campaign. I started running that campaign in 1978, and have been running it on and off ever since. I currently run it one evening a week.
People have occasionally expressed interest in seeing the system, as I occasionally refer to it in discussions in the newsgroups rec.games.frp.misc and rec.games.frp.advocacy. Until recently, though, the system did not exist in a convenient electronic form - indeed, some of it had never been written down at all.
I've now put some of the system into html, partly because of these expressions of interest and partly for my own convenience. I'm making these portions of the rules publicly available except for a few parts which are only for gamesmaster use. These latter parts are, at any rate, often in a cryptic form that would likely not be very useful to those who don't already know my campaign fairly well.
If you read these rules, I'm interested in any feedback you may have - including what parts of the rules you would like to see next - either by email to me at firstname.lastname@example.org, or by posting on rec.games.frp.advocacy.
