" To Isengard! Though Isengard be ringed and barred with doors of stone; Though Isengard be strong and hard, as cold as stone and bare as bone, We go, we go, we go to war, to hew the stone and break the door; For bole and bough are burning now, the furnace roars – we go to war! To land of gloom with tramp of doom, with roll of drum, we come, we come; To Isengard with doom we come! With doom we come, with doom we come! "

― J.R.R. Tolkien , The Two Towers (The Lord of the Rings, #2)
