The mole-kin or House of the Mole (G."Thlim Doldrin") were one of the great houses of Gondolin.They were the greatest part of the kingdom's delvers, miners and prospectors and were led by their Lord or Master Maeglin Lómion.

Notes:[]
In the book of lost tales the mole-kin are counted as Gnomes or Noldoli, though perhaps to some degree akin or intermixed with descendants of Orcs or Gongs.They could perhaps be revised as Tatyarin Avari, perhaps remnants of Eol's people in Nan Elmoth. Blodrin, Narthseg and Ufedhin could be considered members of this, very uncanny, tribe.
