consumptive-sphinx:

i. 

He knows himself as Maedhros. 

Nelyafinwë and its derivatives would only have alienated Fingolfin’s supporters further – third Finwë,

Fëanáro named him, as though his half-brothers did not count. Russandol he has not heard since childhood; hearing Findekáno use it now is to pour salt into an open wound. And since Thangorodrim Maitimo has felt like a cruel joke.

So he takes Maitimo and Russandol, the two of his names that are not insults, and puts them together. Maedhros fits him well; it is the language of this new land, a name that has never been turned against him. He wears it with pride.

ii. 

Those who love him call him Macalaurë. 

Maglor is hideous, Canafin even more so. His name is Macalaurë

Canafinwë son of Fëanáro, and Elu Thingol – see, he is willing to use Sindarin names for those who want them – cannot change it. Names are important and Macalaurë will not give his up. 

Others call him Maglor, call his land Maglor’s Gap, and

Macalaurë becomes accustomed to it but never fails to notice. 

iii. 

He is Tyelcormo, Celegorm, what does it matter? As long as he is not called Turkafinwë, he does not care. 

iv. 

His brothers call him Moryo, and his allies call him Caranthir, and his enemies call him dark one, red faced, and he calls himself Carnistir still – a habit of millennia does not break easily – but he does not, truly, care. 

v. 

He calls himself Curufin, Curufinwë. For

Fëanáro to give him his own fathername is a rare gift, a show of inheritance that not even Nelyo was given, and Curufin values that gift more than he values the language it was given in. 

He is skilled, and like his father – not merely his father’s echo, as Atarincë

would imply, but his father’s favored son. They say he is Fëanor come again, and Curufin smiles. 

vi. 

They were always Ambarussa, before – his brother’s mothername was Ambarto, but together they were Ambarussa. his name is Ambarussa now. He could change his own name, but he will not change his brother’s.
