My namesake got mentioned as a prominant person of power in Sigil. I'm happy.
Her Serenity was listed as (LN female, unknown race). I strongly object to giving Her an alignment, especially an alignment of LN. Neutral? Likely. LN? Heck no. I'm also not sure that I agree with statting Her as female either. We assume, but we don't know...
Really? Those are...interesting choices.
Female: Sure, especially if any credit is to be given to Pages of Pain, which pretty darn definately established the Lady as feminine, though whether her having a gender actually means anything is detabable.
Lawful Neutral: The Neutral part makes sense (it's pretty much a must), Lawful, well, it's not impossible. Assuming you take Lawful Neutral to mean her law, and the laws that bind the Lady's own existnce being pretty much compulsory on her. ie. don't let yourself be worshipped as a god, only you can control the portals, I am the one and only ruler of Sigil, that sort of stuff. Mortal law might be considered so far beneath her as to be irrelevant. It doesn't mean the Lady has to act lawful by mortal (much less human) standards. Regardless, giving her an alignment has to be a mistake.
Unknown Race: This is actually kind of troubling. Even saying unknown implies that the Lady has a 'race.' Meaning she's a physical being of some kind, not a spiritual one, a godless god, or some other, non-normal existence (essence of Sigil, etc.). It seems too, well, mundane.
