[Dimturiel]

Could it be Turin?


We left our homes
for the new lands.-Turin being sent from Dor-lomin to Doriath
With my high hopes
I failed my friends.- The kingdom of Nargothrond is destroyed because of his high hopes
Rain pouring down,-it was raining when Nienor arrived near Brethil
creature unknown
that brought us doom.-Glaurung, coming to attack Brethil
Now I am left to talk to myself.
What now to do? Sit down or play?-after Glaurung is killed, Turin debates whether he should seek his kin in Doriath or avoid them so as not to cast his doom upon them
But the doom came: Forever stay.-Mablung brings him the tidings which prove that Nienor was Niniel and Turin kills himself.

I know I must be way off...
