The Chronicles of the Teleri
Sirion
As we moved southward along the River Sirion, we knew that our journey would bring us to within sight of the Great Sea, Belegaer, an event that we looked forward to with both excitement and trepidation. We knew that our kindred the Vanyar and the Noldor must have passed over the sea on their own journey to Valinor, but still we were apprehensive about confronting what could be the greatest obstacle to our reaching the Blessed Realm.
But the reality surpassed even our greatest expectations. For when we reached the great delta that is the Mouths of Sirion, we beheld a sight more wondrous than any we had yet seen in our travels. The vision of the glittering, shifting water, coupled with sound of the waves on the shore immediately captured our hearts, and we felt a joy such as we had not experienced since we had first awoken to behold the stars of Varda shining in the heavens. We had ever been enamoured of water in all its guises, but our love of the sea transcended even that we had for the Waters of Awakening, where we had first come into the world. But, despite our love, we perceived that we had been correct; that Belegaer was a mighty barrier in our westward journey, one we might not overcome without the help of some higher power.
So, once again, we halted in our journey, and made a home for ourselves beside the Mouths of Sirion. But, unlike our home in Thargelion, we hoped that the Havens of Sirion would be but a temporary abode, and that the Valar would soon heed our desire to join our kindred in Blessed Realm.
For a long while we waited, but still the Valar did not appear to us, and we began to despair. But we were not to be left entirely alone on this forsaken shore. For two of the Maiar, the servants and helpers of the Valar, came to us from the sea, and we petitioned them to help us. However, although mighty beings, Ossë and Uinen could not bring us to Valinor – the granting of such a request was the province of the Valar alone. So instead they became our teachers, telling us many things about the great ocean that we had come to love. Uinen taught us of calm seas and steady currents, and how the sea could be a kindly and helpful entity, and for her gentleness and compassion we loved her. But it was Ossë that we revered most, for he taught us the music of the ocean, and thus we were able to pour our love of the waves and the water into our songs, and they became more delightful to the ear than ever before.
But although we were grateful to Ossë and Uinen for their teachings, and ever after they were venerated by us, it was the Valar that we truly longed to meet, for then we would know that our journey could continue, and we could pass over the sea to Valinor.
