Faenor is a Falmer / snow elf. Yes, this is a man.
His birth was a miracle actually - he was born in blackreach, born by the creatures that are known as "Falmers" and who are the mutated abominations which once used to be known as "snow elves" or "ice folk" - but this is centuries and centuries ago. Enslaved by the dwemer, poisoned and helpless, the Falmer people even outlived the Dwemer, the ones who turned them into what they are now - living in caverns and old ruins, blind and ugly, not to be seen as elves any more, having lost everything - their culture and their own country. Faenor however.... was born as a "true" snow elf, not mutated, not blind, handsome and full of questions.
Many Falmers hated him because they did not understand what he was and why one of their own kind would give birth to a creature that looks way too much like the inhabitants if the surface world. So his life was not easy and Faenor knew he was different even without seeing himself inside a mirror.
Dunmer adventurers found him inside a dwemer ruin, he was a teenage boy back at that time. They mistook the child being a captive of the evil Falmers and took him with them, up to the surface where one of them raised him as his own son. To most people Faenor is an Altmer, a high elf with a very pale skin and unusual eyes and only those who look closer and have certain knowledge about the dark past of the country might understand, what he truly is.
