Yep, Grayza was an attempt at a Servalan-type character but turned out to be Servalan-lite. Very, very lite. Oddly enough (speaking as a B7 fan), the Grayza character doesn't really irritate me. Compared to Sikozu she's almost great. I'm kinda curious about that, too. I haven't heard anything about them since they were announced, and that was ages ago now.
