New Challenge: Title Track
Tolkien's titles range from epic to lyrical to metaphorical. This month's challenge selected 125 of them as prompts for fanworks.

The Sentiment of Steel, or "Sentiment du Fer": a fencer’s ability to use his sword to feel and manipulate the opponent’s sword. A concept with which Glorfindel and Ecthelion are far too familiar.

“Everyone knows the heart of Ecthelion is as cold as ice. Only the quest for vengeance heats his blood.” Glorfindel’s words were delivered as a jest, but he knew as soon as he heard them ringing from his mouth that he had failed to disguise the bitterness that colored them.

With the first snow memories of how it once has been between them arise.

Fingon and Maedhros' relationship through the ages, from the point of view of two outsiders (who may or may not have played a part in its trajectory).

Heavily rewritten, again:
This story first appeared in The Silmarillion Writer's Guild's Akâllabeth in August.
Summary, from the Akâllabeth in August page:
Sauron has been taken prisoner by Pharazôn but nurtures an ever-growing influence. In the midst of a Númenor increasingly divided, a young Anárion works quietly after rebellion, discovering both love and betrayal in its midst.

Artanis had a part in the First Kinslaying.
Warning for violence. (This is the First Kinslaying. There's violence.)

(Also cabbages, and kings.) Ficlets which are, even by my standards, too short to stand alone (and aren't part of a series).
#6: Finduilas contemplates sickness and Nienor.

Húrin and Morwen undergo an important courtship ritual.

Written for the prompt - the Turin pairing of your choice having disastrous sex. But it's always a disaster, when Túrin's around!

Maglor in the moments that precede and follow Maedhros' death.

The story of the fifth companion of Finrod and Beren to die in the dungeons of Tol-in-Gaurhoth.

On the eve of the War of Wrath, Ingwion asks his father to be the one to lead the Vanyar in battle. Afterwards his family dinner highlights a hidden motive in his eagerness to journey to Beleriand.

Elrond remembers Sirion, and learns the art of the sword.

Of the history of the Elves at Cuiviénen and the development of the the three tribes, of the family of Elwë and the discovery of Oromë, of how Indis received her name and Ingwë earned his, and of the honor duel between Imin and Ingwë to decide the leadership of the Minyar and the future of the Eldar.

In an alternative universe Aegnor and Andreth do marry. That does not stop the philosophical debates. Or more mundane questions. Where Angrod's worries about his family are a little more prosaic and involve Beleriand's version of baby name books.

Tar-Míriel, beyond all hope, is rescued.

So, Curufin, son of Feanor, is conveniently walking around with a dwarf-made knife at his waist that just happens to be suitable for cutting a Silmaril out of Morgoth's iron crown and he just happens to give Beren enough provocation to rob him of his possessions, including the knife.
Here is a slightly AU gapfiller on the subject of the early history of Angrist, the knife that would cleave iron as if it were green wood.

The story of two elves from Nargothrond, neither important enough to be mentioned in the family trees of kings or heroic songs, who lost their names in Angband's slavery. The childhood companion of Finduilas Faelivrin must take the princess's identity to survive in the enemy's hands. Another prisoner, regretting he did not join Beren’s quest, tries his best to save her.
or
The later half of The Silmarillion from the POV of prisoners in Angband, as inspired by A Dance with Dragons.

Gil-galad and Celebrimbor have a great life together in Aman, until a certain person from the past shows up.

In dire straits in Araman, Aredhel and Elenwë struggle with more than just the cold.

The story of the first companion of Finrod and Beren to die in the dungeons of Tol-in-Gaurhoth.

A fanfic of elfscribe's "Elegy to Numenor" in which Sauron, recently taken prisoner by Ar-Pharazon, puts terrifying visions into the minds of his guards. (He's being a jerk because he's bored.)

Aredhel, Celegorm and Curufin used to play together as youngsters and were great friends. This story concerns that friendship and Aredhel's desire to leave Gondolin and meet her cousins again after much time and many events have passed.

Celegorm knows the Sinda has no real power to do anything to them.
If it wasn't for his brothers trembling next to him, and the Sinda smirking, he would be utterly convince this was a dream. Afterall, that made more sense than a Sinda somehow dragging their souls along with his to this cursed place.
Mild violence warning for mention (and description) of future Silm events.
