[Quiet Man Cometh]

I sort of assumed that he was one of those characters who's job is to impart knowledge to the characters, though he didn't seem to do much else after the one encounter after the barrow wight. Of course, I only read LOTR so far and I hear allusions to him being more important or at least having more relevance earlier on. If memory serves, he passed on the legend of Luthien and Beren to Frodo et al in Fellowship, did he not?
