[Beregond]

I refuse to go down in history as the thread-killer! Here's a hint - this person is...secretive.

And...this third age male mortal character from LotR who lived in the land of Gondor, but not in the White City, is NOT Imrahil or any Lord or Ranger. Nor is he dead. He did not quite fight in the Siege of Minas Tirith and was old, but not necessarily past fighting age. If there is one clue you should pay less attention to, it would be "Gondor".
