I finally got the scene...I think the reason I didn't get it before was because I'd already gotten SH's confession, and the school attendance record is another trigger for that conversation, but it's ancient like the old helm and statue, remnants of the war between the Nightsong guys and the druid/harpers, the missing children poster I was assuming was much more recent.
I guess the real thing I'm asking is how old the ruins are, was the blighted village destroyed during the old war or was it more recent?
