Riding with the king
   Flowing far down through the gates
   The deadly great rivers
   and streams of fire flow down the Thangorodrim
   And fill Ard-Galen.
   With the blades of steel
   The orcs they ride, and balrogs
   and Glaurung the great.
   Night sees armies ride down from Iant Iaur
   From this night it was called Anfauglith
   ...
