Thank you.
And now for the final posts - I did some research and find no record in Tolkien whether Uldor or Ulfast or both survive the Battle and rule in Dorthonion, although I see that Brodda did. So we can have it that either one kills the other, or both kill each other, or neither, before the treason. Which way shall we go with it?
And Tathren has to appear before Caranthir; after that, I think this is concluded.
