from The Silmarillion, Chapter 16, Of Maeglin,
Then
Turgon sat in his high seat holding his staff of doom, and in a stern voice spoke: 'I will not debate with you, Dark
Elf. By the
swords of the
Noldor alone are your sunless woods defended. Your freedom to wander there wild you owe to my kin; and but for them long since you would have laboured in thraldom in the pits of
Angband. And here I am King; and whether you will it or will it not, my doom is law. This choice only is given to you: to abide here, or to die here; and so also for your son.'
Then Eöl looked into the eyes of King Turgon, and he was not daunted, but stood long without word or movement while a still silence fell upon the hall; and Aredhel was afraid, knowing that he was perilous. Suddenly, swift as a serpent, he seized a javelin that he held hid beneath his cloak and cast it at Maeglin, crying: 'The second choice I take and for my son also! you shall not hold what is mine!'
But Aredhel sprang before the dart, and it smote her in the shoulder; and Eöl was overborne by many and set in bonds, and led away, while others tended Aredhel. But Maeglin looking upon his father was silent.
It was appointed that Eöl should be brought on the next day to the King's judgement; and Aredhel and Idril moved Turgon to mercy. But in the evening Aredhel sickened, though the wound had seemed little, and she fell into the darkness, and the night she died; for the point of the javelin was poisoned, though none knew it until too late.
Therefore when Eöl was brought before Turgon he found no mercy; and they led him forth to the Caragdûr, a precipice of black rock upon the north side of the hill of Gondolin, there to cast him down from the sheer
walls of the
city. And Maeglin stood by and said nothing; but at the last Eöl cried out: 'So you forsake your father and his kin, ill-gotten son! Here shall you fail of all your hopes, and here may you yet die the same death as I.'
Then they cast Eöl over the Caragdûr, and so he ended, and to all in Gondolin it seemed just; but Idril was troubled, and from that day she mistrusted her kinsman.
