I presumed that was where your confusion over whether she was 35 or 40 came from... Thirty-something looks would make more sense, too, seeing how she is only half of a Nightwalker, and should therefore age faster than a pure Nightwalker... (Pure Nightwalkers age 1.5 times slower than humans, so a 40-year old pure Nightwalker would look comparable to a human in mid-late twenties (40/1.5=26.6...).

(I'll dig for your character sheets in a bit; I'll fetch Aemoten's sheet first... On another note it seems that the two most prominent crawlers have missed both pieces of Guild news featuring The Prophecy... Pity. Will try others later. Edit: Oh, wait, got one out of a tertiary cache.)
