This is something I wrote last year and it is supposed to be in the style of a Greek epic poem. I don't think it's very good, but here you go anyway...
It was going to take so long to finish the whole story, I just wrote an epilogue. Kind of dumb of me, but oh well.
The Silirvenelion
Ossë’s unappeased anger lashed the ship of the elf
Onto the shores of unknown lands.
The people of the elf lord, Earandir, no longer honored the fiery maiar Ossë.
No longer did they sacrifice and pray to the ocean spirit.
Instead of decorating his altars with garlands,
They sat at home, with lavish riches and jewels.
Vain and foolish people! The wrath of Ossë was great.
In a fury he came to the island of the elves and promised
To send such a storm as to make the island’s foundations
Crack and the sea swallow the land forever.
The Earandir, noblest of all elves of Leithian,
Left the sinful isle with some faithful companions in his
Silver ship, they purposed to sail to Valinor, home of the Valar,
To beg forgiveness and beseech the Valar to spare the faithful.
Nienna, the sorrowful Vala Queen, loved Earandir, for he was noble and good.
She was his protector and guided him ever on his quest.
The storm continued to surge and crash about the ship.
The Nienna left her lonely halls in the west and flew
To Taniquetal where Manwë, lord of the Valar, dwells.
“Lord of Arda, why do you allow the winds which you rule to
Surge unchecked at Ossë’s bidding? For he is setting his will
Against Earandir, a noble elf, and seeking to destroy him in
A storm. Then Manwë Súlimo drew aside thoughtfully.
“Nienna, Ossë’s storm will not destroy Earandir.
But Earandir’s journey will not be without peril.
For he has the Silvirenel, the diamond jewel created by Aulë the Smith
With a drop of dew from Telperion, silver tree of light brought to
Life by Yavanna Kementári, imprisoned in it. The same dew
Which now laces the heavens as Varda’s creation of the stars.
The Silvirenel was stolen by Amrod, son of Fëanor, when the Noldor
Rebelled. When Amrod lay dying on the shores of the Grey
Havens, he passed it on to his oldest son, Earandir.
Earandir still bears that magical jewel of the Valar, and
Unless he relinquishes his claim for it, he will perish in the end.”
Thus spoke Súlimo to Nienna, Lady of Hope and Grief.
Nienna then withdrew from Manwë back to her halls in the West.
Meanwhile, Earandir’s ship had been driven into
The shallows of an island they did not know.
The weary men waded onto the shore, taking what little
Food they still had left. After eating a little food,
Noble Earandir had a search party arranged. With him
Went Morglìn. Morglín was a very young and fair elf.
He was like Fëanor, his grandfather, in appearance,
But like his father Maedhros in spirit. While this group
Was exploring, Uialmîr, youngest daughter of the
King of that land, had seen them; whereupon she
Flew back to the palace of Gwaeol the king. The people
Of this land were a race descended from Maiar and Teleri Elves.
They were beloved by Vána the Ever-Young and Ulmo.
Ulmo raised the island out of the sea and Vána
Planted silver trees and named it Brethildôr, land of silver birches.
Upon hearing his daughter’s tidings, Gwaeol set forth
Himself to find these foreign elves who were in his land.
He saw them drawing near the city gates. The men
Were worn and weary, but Earandir still looked strong
And fair, as it always was with the proud Noldor elves.
Gwaeol welcomed them to his city, for he could
Tell the tall elf lord was of noble blood. The Noldor
Of Leithian were led to the Brethildôrian palace
And could not but marvel at the beauty and grandeur of it.
Upon the ramparts the crimson and silver flags unfurled in
The breeze. The towers and walls were of marble, but
The great hall itself was of the silver trees of that
Land. It was made against a tall mountain with a hill
On the northern side. Arien, in her flaming golden chariot had
Just risen and begun her path across the sky, making
The mountain shine like burnished gold and threw a
Golden mist across the land. The Brethildôrians
Welcomed these strangers, for it was long since anyone
Had been to their land. That night a feast was held for Earandir
And his men. After the feasting, King Gwaeol
Told them his story: “Many years ago, one of the maiar,
Ninimiel, handmaid of Vána, fell in love with Turcúdil, an
Elf lord of the Teleri. Ulmo, the Lord of Water and lover
Of the Teleri, and Vána were both pleased. Ulmo raised
This island and Vána filled it with trees and flowers
For the elf and maia. Both Teleri and maiar joined them on
This fair isle. I am the only son of Ninimiel and Turcúdil
And am now the king of this island, for they have
Returned to the Undying Lands. My wife is dead,
And I have two daughters, Morfinwen, the oldest, and Uialmîr.
Now, tell me your story.” Then Earandir began, “I am the oldest
Son of Amrod, son of Fëanor, maker of the Silmarils. I
Came with my father’s family from Valinor, but shortly
After arriving, I followed another elf, Lokë, in his
Search to start a new country. We were joined by
Many others, including my brother Tarfëar, and
Lived for awhile in peace and joy in our island kingdom
Of Leithian, of which Lokë was king. But alas, our
People fell from their pious ways and failed to honor
The Valar and other spirits. Ossë came to our land in a
Fury and told us that unless we repented, he would destroy
Our land. But we did not heed him. I have set out with
A few faithful to beg the pardon of the Valar for those
Who are still faithful to the Rulers of Arda.
We have had many perils, for Ossë’s wrath is great.
First, my brother rebelled and tried to take over command
Of my ship, even killing one of the other commanders.
We were forced to tie him in the hold below deck,
But there he found a knife and killed himself.
We have been be set by both storms and loss of winds.
It has been one hundred days since we set out and we
Are not even sure of which way Valinor lies. We
Have very little supplies and our ship is in need of repair.”
The hour was late, and Gwaeol said they would
Hold council the next morning. It was arranged that the
Brethildôrians repaired the ship and filled it with supplies.
Gwaeol knew not the exact way to the Blessed Realm.
For he had never been there and only knew what he had
Learned from his parents. After two weeks in Brethildôr
They set sail once more with fair weather and an east wind.
Ossë was, for a while, restrained from his wrath by his wife
Uinen and Ulmo. After four weeks from sailing from Brethildôr,
The elves caught first site of Alqualondë, the swan
Haven. So Earandir arrived in the Blessed Realm
Of the Valar as no other beside Eärendil the Mariner had
Ever done.
Epilogue
After reaching Valinor, Earandir was met by Mandos, one of the Valar, and was told that none but Earandir could set foot in Valinor. Mandos then took Earandir to his Halls of the Dead where Earandir met with his father, Amrod. Amrod told him that unless he returned the Silvirenel to Varda, all of the descendents of Earandir would suffer. Nienna then took Earandir from there to the Ring of Doom where the Valar sat for council. Earandir asked for forgiveness for the faithful and it was granted. The evil elves of Leithian were killed, but the faithful continued to live there. Earandir gave the jewel back to Varda, but she returned it to him because of his valor and courage to sail to Valinor. He then returned to Brethildôr and married Morfinwen and they lived there until Gwaeol made him king. Morglin ruled Leithian.
