Maedhros was deep in thought all the next day. He decided to go to Fingon and Maglor and seek their counsel. Fingon was uncertain. "This may be the chance of release you sought from your Oath. However, you will have to change your very identity, though your fëa be the same. You will no longer even be one of the Eldar! But if you take this chance, I will ask a boon of the Valar to be the second person they saw." Maglor thought this wise, and spoke his agreement. He did not know if he wanted to play a role in the prophecy Lord Mandos had revealed, yet if he could support his brother and cousin, he could do so without being on the front lines of the battle. Though he was a capable warrior if the time called for it, his nature was more that of a singer and music maker.
Maedhros did not know what to say, so deep was his gratitude. He did not know what his future would be or what trials he would face. But in that moment, knowing Maglor and Fingon would stand with him as they did in life, the heavy weight of uncertainty seemed to lift, just a little. This would be the strength that sustained him in his life as an Atani, though he foresaw it would be harsh.
The Valar granted him his second audience. He stood before them, his uncertainty eased by the two at his side. "This task you have set before me I willingly accept."
Maglor and Fingon then petitioned the Valar for the chance to play a role in Maedhros' life as Atani. The Valar knew that the second person in the vision would also be vital. Knowing Fingon's loyalty proven many times over, they granted him this boon. Maglor, however, was the subject of a more complicated discussion. They discussed his role as accomplice in the Kinslayings. What was also taken into account was his attempt to advise Maedhros against the last attempt at stealing the Silmarils. Though failing to hold firm, the Valar saw in that a potential to play a role as an advisor and helper. They granted Maglor this, after long deliberation.
After Maedhros told the Valar of his acceptance, and Maglor and Fingon informed them of their choice to aid him, they had a more personal errand. Nienna was walking about the Halls, as was her daily custom. Seeing the flash of her distinctive grey pass the corner, Maedhros called to her, his voice carrying all the weight of his years and longing.
"Please, I must see my father and brothers!" The response the Sorrowful One gave was full of understanding. Without a word, she beckoned and continued her winding path through the Halls.
The trio followed gratefully. Fingon, however, was hesitant to open dialogue about happenings that he had up till now kept silent about out of compassion for his friend. Yet he followed despite his misgivings.
A/N: Sorry if this is really short, but I figured it would advance the story.
