Mercy, Love by Elleth

Chapter 7

It is Maedhros' heart that uplifts in hope with tidings of the victory of Lúthien and Beren, and although he cannot contain all his brothers, he seeks a new league and a new unity, a new purpose. He sways Fingon by no longer speaking of death for himself, although his sleep is plagued still these centuries later.

And Fingon himself dares to hope, thinks of that old grief and guilt and the dagger slicing off Maedhros' right hand - and vows to be the hand he took and lay all his grief at the feet of Morgoth, where it rightly belongs.
