The fall of Carcapon
Carcapon was the greatest lieutenant of Melkor. He was feared by all people who had the bad luck to have seen his horrible face. His name of old was unknown and he did not reveal it to anybody. He was one of the strongest Ainur known on Arda and where he walked, the earth shook
Now once he challenged Mairon to battle. Mairon was afraid but still he fought. His weapons were a flail and a shield. Carcapon had a sword and a shield. The fight was in a hall and many other creatures of Melkor were present
The first move of the fight was delivered by Carcapon. He swung his sword at Mairon's neck. But Mairon was quick and he moved back at once. Then he swung the flail twice around his head, and brought it down in a swing towards the waist of Carcapon. The spikes of the ball crushed his muscle and blood appeared there. Carcapon in great rage stabbed his sword at Mairon. Mairon was taken by surprise, and he raised up his shield. But it was just a trick. As Mairon blocked the stab of the sword, Carcapon flung his sword down onto Mairon's leg. Black blood gushed out. Mairon fell to the ground, vomiting blood. As Carcapon was about to kill Mairon, he flung his sword away.
"Get thee gone, worm, thou art not worth killing, "said Carcapon. And then he turned his back on Mairon and started walking away, laughing softly.
But Mairon was not utterly spent. He remembered his days of greatness at the dwelling of Aule, and the fear of the guards of Utumno. Slowly, still vomiting, he got up and, hunched, he crept to Carcapon's sword. He lifted it up then, and screaming, he ran up to Carcapon, who turned back and looked. But Mairon was too fast, and before Carcapon could react, he had stabbed him. So fell Carcapon, and since then Mairon was Melkor's greatest lieutenant.
This is the last to be told of Sauron in the First Age. The rest of his stories are after the overthrow of Melkor
