Summary: My ideas on why Fëanor and his sons took their Oath. More emphasis on family loyalty than on the Silmarils. Yes, I like writing free verse.

"Morgoth he shall be called!"
The Spirit of Fire cried out, stricken by grief and rage.
"By his slaying of my father, our king,
he has named himself the Dark Enemy of us all!"

And so powerful were the words of Fëanor
That in truth he renamed the greatest of all beings in Arda.
But no words of the son of Finwë could bring Finwë back to life
Nor heal the hurt done to the Elven-kingdoms.

Later, then, Fëanor returned to the city of Tirion.
For love of his father he spoke many words, fierce and dangerous,
And at the last, he spoke an oath of vengeance and hatred --
The most dangerous words ever heard in all the realm of Eä.

Seven voices rang in answer
The sons of Fëanor, leaping to stand beside him, swords drawn
They repeated the oath he had sworn, in voices of power and wrath
But their true meaning was this:

"We love you, Father; you do not stand alone;
We will stand with you and walk with you,
No matter what your road may be. You have the loyalty of your sons."
For love of Fëanor they bound themselves with his oath: seven brave young princes.

Maedhros the eldest, tall both in body and heart,
He would spend his life trying to set good against the evil his oath forced him to do.
Maglor, created by Eru to sing of beauty,
Swore to become a killer, his minstrel's hands red with the blood of others.

Celegorm the hunter, friend of Oromë,
Torn from that friendship by hatred for Oromë's greatest foe.
Curufin the crafty, heir to his father's hands and mind,
Amidst oathkeeping he brought Celebrimbor, creator of beauty and key to disaster.

Caranthir the dark and furious, a rage to set against Morgoth's rage,
He kept his oath with a hatred that sprang from his love.
Amrod and Amras, twin huntsmen, so alike they could scarcely be named apart,
Fought all their lives for the father whose youngest sons they were.

The finest of the Noldor heard his children's voices,
And his heart was both eased and grieved.
Fëanor knew that the oath would bring pain,
But with the help of his sons, he knew it would also bring victory.
