Did you ever play in the Rookhausen chat, hosted by Sword & Sorcery, using 3rd edition d20 rules and the Ravenloft setting version published by Arthaus? I designed the original idea of that chat, although it was of course expanded by volunteer DMs and many players. I was kicking around some of the old web pages on my site, trying to give some of them the cleanup they desperately need, when I ran across these old hidden pages, which I had only shared with a select few back then.
Darklord of Rookhausen pages:
Janisar 3.5
Janisar 3.0
Curse of Janisar
This stuff was never official or canon. It was merely material designed for an online setting we hosted at Sword & Sorcery. Nonetheless, I thought some players out there who are Ravenloft fans might be interested.
