Welcome to the Downs,
Turin and
A_Brandybuck 
I hope that you enjoy yourselves here.
My goodness, there seems to me to be a good deal of scepticism concerning the talkative nature of Turin's sword. Now, I am a very sceptical person when it comes to unexplained phenomena in real life, but (absent the ludicrous) I am quite happy to suspend that scepticism when I read a
fantasy novel which contains elements of faerie, mythology and legend.
Can anyone offer a plausible explanation as to why Gurthang
could not, or
should not, have talked?
