Hi, Himring.  Just realized I never responded to this!  I've gotten similar reactions to this story before, people seem to be surprised by the idea that Celebrimbor would have much interaction with Turin.  Not sure why!  Back when I submitted this story for review on HASA, one reviwer recommened rejection on the grounds that it was "uncanonical", which I thought was absurd.  There was clearly a group of Curufin's and Celegorm's followers in Nargothrond, and in this story I assume (reasonably, I think?) that Celebrimbor retains a lot of influence with those folks.  Certainly I can't see Celebrimbor supporting Orodreth's policies!
