Elfos
Elrond lembrou-se das batalhas de thangorodrim no final da primeira era que levaram à destruição de Beleriand.
Thereupon Elrond paused a while and sighed. ‘I remember well the splendour of their banners,’ he said. ‘It recalled to me the glory of the Elder Days and the hosts of Beleriand, so many great princes and captains were assembled. And yet not so many, nor so fair, as when Thangorodrim was broken , and the Elves deemed that evil was ended for ever, and it was not so.’ ‘You remember?’ said Frodo, speaking his thought aloud in his astonishment. ‘But I thought,’ he stammered as Elrond turned towards him, ‘I thought that the fall of Gil-galad was a long age ago.’ ‘So it was indeed,’ answered Elrond gravely. ‘But my memory reaches back even to the Elder Days. Eärendil was my sire, who was born in Gondolin before its fall; and my mother was Elwing, daughter of Dior, son of Lúthien of Doriath. I have seen three ages in the West of the world, and many defeats, and many fruitless victories.
Existem elfos mais velhos que Elrond na Terra Média (Círdan, Galadriel e Celeborn, por exemplo)
Hobbits
Na história fictícia, Bilbo é o autor do Silmarillion. Isso conta a história de Beleriand, então ele deve saber.
Ele canta de avernien (o litoral de Beleriand) antes do Conselho de Elrond.
Eärendil was a mariner that tarried in Arvernien; he built a boat of timber felled in Nimbrethil to journey in; her sails he wove of silver fair, of silver were her lanterns made, her prow he fashioned like a swan, and light upon her banners laid.
Parece que ele também passou essa tradição para Frodo, já que ele está ciente da história da espada Sting
‘That would not help us now,’ said Frodo. ‘Come! Let us see what Sting can do. It is an elven-blade. There were webs of horror in the dark ravines of Beleriand where it was forged. But you must be the guard and hold back the eyes. Here, take the star-glass. Do not be afraid. Hold it up and watch!’
Homens
Aragorn é descendente de Luthien e conhece o folclore, ele aprenderá de Elrond, ele certamente sabe de Dorthonion que foi imediatamente ao norte de Berleriand.A história dos Barrowdowns é discutida nos apêndices do Senhor dos Anéis, parece que os Dùnedain mantiveram viva a história de Beleriand.
‘It is said that the mounds of Tyrn Gorthad, as the Barrow-downs were called of old, are very ancient, and that many were built in the days of the old world of the First Age by the forefathers of the Edain, before they crossed the Blue Mountains into Beleriand, of which Lindon is all that now remains.
Tom Bombadil
Tom Bombadil conta aos hobbits do mundo quando era mais jovem.
When they caught his words again they found that he had now wandered into strange regions beyond their memory and beyond their waking thought, into times when the world was wider, and the seas flowed straight to the western Shore; and still on and back Tom went singing out into ancient starlight, when only the Elf-sires were awake.
Barbárie de mão
Barbárvore canta de Belariand
In the willow-meads of Tasarinan I walked in the Spring. Ah! the sight and the smell of the Spring in Nan-tasarion! And I said that was good. I wandered in Summer in the elm-woods of Ossiriand. Ah! the light and the music in the Summer by the Seven Rivers of Ossir! And I thought that was best. To the beeches of Neldoreth I came in the Autumn. Ah! the gold and the red and the sighing of leaves in the Autumn in Taur-na-neldor! It was more than my desire. To the pine-trees upon the highland of Dorthonion I climbed in the Winter. Ah! the wind and the whiteness and the black branches of Winter upon Orod-na-Thôn! My voice went up and sang in the sky. And now all those lands lie under the wave, And I walk in Ambaróna, in Tauremorna, in Aldalómë, In my own land, in the country of Fangorn, Where the roots are long, And the years lie thicker than the leaves In Tauremornalómë.
Maia
Graças a um excelente comentário, os vários Maiar ainda em torno da Terra-média na terceira idade teriam conhecimento ou mesmo experiência direta de Beleriand.
Sauron e o Balrog estavam na terceira idade, Gandalf e Saruman e os outros Istari teriam conhecimento de várias fontes, mesmo que nunca tenham visitado pessoalmente em suas formas anteriores.Árvores
Velho salgueiro e seus parentes, onde eles são antigos, eles parecem ter memória daqueles dias.
It was not called the Old Forest without reason, for it was indeed ancient, a survivor of vast forgotten woods; and in it there lived yet, ageing no quicker than the hills, the fathers of the fathers of trees, remembering times when they were lords. The countless years had filled them with pride and rooted wisdom, and with malice. But none were more dangerous than the Great Willow:
Anões
Os anões parecem ter poemas e canções que relacionam a primeira idade, então alguns claramente tinham conhecimento de Beleriand. De fato, Gimli fala disso na Câmara de Mazarbul.
The world was fair, the mountains tall, In Elder Days before the fall Of mighty kings in Nargothrond And Gondolin , who now beyond The Western Seas have passed away: The world was fair in Durin’s Day.
