[Nerwen]

Explanation-

In Blessed Lands I came to be
Yet I left them behind
Abandoned we were
In our hour of need

Through impossible odds
We finally arrived on these shores
Where darkness dwelt
We won't forget -Flight of the Noldor, burning of the ships, passage over the Helcaraxë.

A binding oath
A promise to be kept -The oath he swore to Barahir.
Those things spurred me on
To the place where darkness slept -Tol-in-Gaurhoth.

They picked us off as time passed -wolves ate the prisoners one by one (just like in a certain game).
They wanted to save me for last
But I couldn't let him die
So now I say goodbye -Finrod, left for last, killed the wolf that came for Beren but was mortally wounded.

Edit: okay, I won't, then.
