[Common knowledge - you may have heard this about even if you haven't met him]

So You wish to know my story? I'd rather hear yours but you are right, it is fair that I share mine too.

My name is Giliathon, but I was called Elnio by my kin - Lindai of far Alpalondë. I am sailor, a navigator. I have guided our ships to from west to east, from north to south, to long lost harbors of Brithombar, Eglarest and Eldalondë. I've also kept books and records of our travels for I have more patience for writen words than my kinsmen.

You ask what I am doing here, so far inland? We were asked to bring special guest to Mithlond, wait for him and bring him home. So I use my time to visit friends of old, see new places and hear new stories to bring with me. 

Who the guest is? He calls himself Laurefindil. Ask him yourself abouth his goal. He is here in Imladris.

So, what is your story now...

[Not so common knowledge]

Years of Trees
Born on Tol Eresea among people of Olwë some time before Darkening of Valinor and exile of Noldor. Like his father, he became sailor and learned hidden lore of heaven and mathematics from his grandmother that came from Tirion. Mother was courtier of Eärwen and her mother of Indis. Thanks to his skill and political connections of his family he became navigator on Swan Ship assigned to lady Alatáriel.
During the fateful events of the first kinslaying he unsucessfully tried to defend his ship. He was seriously wounded but survived thanks to care of his lady. Thankful and still hopeful for reclaiming stolen ships he vowed to be her guide acros the Great Ocean.

First Age
After coming to Middle Earth and his vow fulfiled he settled on the shores in Eglarest among Cirdian folk. Apart from beeing navigator and teacher of this art, Elnio's lord was sending him to Nargothrond and Doriath when he had messages to exchage with children of Eärwen.
With no love for war he took part in only one battle - Nírnaeth Arnœdiad, after which his inland errands became more dangerous and demanding. Barely escaped city of Finrod when Glaurung fell on it. Road west was to dangerous so he chose safety of Melian's Girdle.
The safety was not long, for Doriath was attacked by dwarves from inside and then by Sons of Fëanor. With his knowledge of hidden ways he was assigned to guide Elwing out of battle and on to Havens of Sirion where for the third time he had to defend himself from Fëanorians.

Second Age
After War of Wrath Giliathon was finally able to sail West, but he did so with large detour, helping Edain, that he came to love and value during his days in Nargothrond, reach Númenor.
Happy to meet with family and friends once more, Elnio couldn't stay in one place. He organized travels to Eldalondë and kept close ties with Dúnedain family that later settled Belfalas.
When his capitan told him that they are to take special guest to Mithlond, he was more than happy to visit his old friends in Lindon once more. He also decided to stay behind and explore southern shores, visit 'his' Númenoreans and bring new stories home.

Third Age
Fall of Númenor and changing of the World caught Giliathon on High Seas. He was swept to the far east and his ship crashed upon the shore. Survivors have build a colony and worked to build new ship capable of oceanic travel. After many decades they finally reached Mithlond. On their way they learned that the world is now much bigger than it was, so Giliathon set out on journey after journey to navigate new paths and new destinations. His house in Lindon stood empty and became library for accounts that he brought from his journeys every now and then.
At the end of his last journey he was reached by a letter from Glorfindel urging him to come to Imladris. Curious to travel inland once more, he took his sword and walking staff and set out east.
