hm, r you sure that's silm77?
if not gangrel, that may be Feanor to Fingon,
or him again to Melkor, that's in Valinor, or Glaurung to Turambar before Nargothrond bridge, but no gangrels involved in the conversations there, methinks.
yet that can't be Frodo to Gollum, for this is Silmarillion thread. Are you sure it is?
