Elves from different forests and houses began to appear in the hidden valley of Rivendell. It was yet another one of Lord Elrond's gatherings, but it was not a very common one. The night was dedicated to Elrond's youngest daughter, Arestel, who turned exactly a hundred years.
Many of their kin was present, especially Lord Celeborn and Lady Galadriel of Lothlórien. From Lothlórien also came the Galadhirm: the brothers Haldir, Rumil, and Orophin. There was Glorfindel also, who lived both in Aman and in Arda, and the Wood-elves of Mirkwood. They were led by their Elvenking Thranduil and beside him stood his only son, Legolas.
The gathering started and many Elves were engrossed in conversations and news of their kin. The twin sons of Elrond, Elladan and Elrohir, came to assist their guests and with them there was also Arwen, who was also known as Undómiel, for she was the Evenstar of her people. She helped in keeping the guests company and Arwen caught her younger sister on sight. Arestel stood in the corner of the room, and was only talking to Glorfindel, whom she considered as best friend.
Soon enough, Arwen saw the Elvenprince of Mirkwood asked Arestel to dance with him. She hesitated at first, but agreed, not wanting to disappoint her guest. The rest of the evening went well. At midnight, the Elves were required to go outside of the house to look into the night sky.
Arestel had led her new friend outside. There it was, the Lunar Rainbow, which only appears once every a hundred years. It was said that the Lunar Rainbow could be seen throughout the whole Middle-earth in only one night.
The Elves gazed in the night sky in amazement. One by one they greeted Arestel an 'Aur ounnar meren', and she was grateful for that. Legolas also greeted her and handed her a silver bracelet adorned with ruby. It came especially from the Elvenking, whom Legolas said was so fond of her.
Thus, it was the fateful night of the Lunar Rainbow when our tale starts.
