They laid him down upon a couch in a house, and danced outside in silence, without psaltery or cymbal. And the next day, rejoicing, to Allathurion they hauled the dragon-crocodile. And Leothric went with them, holding his battered staff; and a tall, broad man, who was smith of Allathurion, made a great furnace, and melted Tharagavverug away till only Sacnoth was left, gleaming among the ashes. Then he took one of the small eyes that had been chiselled out, and filed an edge on Sacnoth, and gradually the steel eye wore away facet by facet, but ere it was quite gone it had sharpened redoubtably Sacnoth. But the other eye they set in the butt of the hilt, and it gleamed there bluely. And that night Leothric arose in the dark and took the sword, and went westwards to find Gaznak; and he went through the dark forest till the dawn, and all the morning and till the afternoon. But in the afternoon he came into the open and saw in the midst of The Land Where No Man Goeth the fortress of Gaznak, mountainous before him, little more than a mile away. And Leothric saw that the land was marsh and desolate. And the fortress went up all white out of it, with many buttresses, and was broad below but narrowed higher up, and was full of gleaming windows with the light upon them. And near the top of it a few white clouds were floating, but above them some of its pinnacles reappeared. Then Leothric advanced into the marshes, and the eye of Tharagavverug looked out warily from the hilt of Sacnoth; for Tharagavverug had known the marshes well, and the sword nudged Leothric to the right or pulled him to the left away from the dangerous places, and so brought him safely to the fortress walls. And in the wall stood doors like precipices of steel, all studded with boulders of iron, and above every window were terrible gargoyles of stone; and the name of the fortress shone on the wall, writ large in letters of brass: ‘The Fortress Unvanquishable, Save For Sacnoth.’ Then Leothric drew and revealed Sacnoth, and all the gargoyles grinned, and the grin went flickering from face to face right up into the cloud-abiding gables.
