Vengeance
Ithil was rising when they returned. Lúthien sat with little Elwing on her knee as Beren set the Nauglamír upon the table. The children stared wide-eyed at the Silmaril that lit the other gems like many-colored flames.
Thingol had been avenged, but alas that the Dwarves' gift of friendship to Finrod Felagund had also been the cause of such strife! And now Doriath was dimmed, and Melian was gone from Middle-earth.
"The people of Doriath need a leader," Dior said, standing tall by the door, having already the bearing of a king.
They departed only days later, never to return.
Tidings
The messenger from the South entered the chamber without a word, carrying with reverence a carefully wrapped package. Dior took it reluctantly, knowing already what it was and what it meant.
Once alone, he set the package on the desk and untied the twine with trembling fingers. The paper fell away to reveal the mingled light of lost Telperion and Laurelin caught in smooth, flawless crystal. The other gems of the Nauglamír flared like many colored stars.
Lúthien Tinúviel and Beren Camlost walked no more in Tol Galen, and to Dior's eyes even the light of the Silmaril was dimmed.
Flight
She screamed when the door flung open, but it was only Nimloth, bearing the shimmering Nauglamír. "Elwing, come!" she ordered, and clasping hands they ran down empty corridors. Far away Elwing could hear screaming, and she smelled fire.
They came to a small closet, and Nimloth slipped the necklace into a pack, and secured a cloak around Elwing's shoulders. "Take this and go. Celeborn is waiting for you at the west gate."
"But Naneth!"
"I love you. Be strong, Elwing." Nimloth kissed her, and pushed her forward.
Clutching the Silmaril, Elwing ran. She looked back only once; Nimloth was gone.
