The Firebeards were a tribe of Dwarves from the Blue Mountains. They were paired with the Broadbeams but each tribe had its own mansion. Tolkien, however never specified if the Firebeards lived in Nogrod or Belegost. At the start of the War of the Dwarves and Orcs, the houses of the other Fathers of the Dwarves were called upon by Durin's Folk, it is unlikely, however, that the Firebeards answered the call seeing as how they had been utterly defeated by Sindar and Huorns in the First Age following the dispute over the Silmarils.
