Maedhros and Maglor decide to surrender to Eonwe to be put on trial back in Valinor. And then, at the last moment, they don't. Framing Maglor's memories of the Nirnaeth Arnoediad and the attacks on Doriath and the Havens of Sirion (or rather, mostly, the discussions among the brothers that led up to those attacks).
Maedhros/Fingon slash (very mild here). Definitely not Maedhros/Maglor slash; however, the subject is raised and the (false) accusation made by others in the story, so if this worries you, please regard yourself as warned.
Also, Maedhros's suicide isn't explicitly told, but strongly hinted at, so has been marked.
This story has been nominated for the MEFAs 2010 by Lyra. Thank you very much!
