Time Isn't Healing [Thranduil Fanfiction/The Hobbit]

For thousands of year, since The First Age, Faeryn never left king Thranduil's side. She was his healer, his greatest and only friend. She had seen many, but felt much more how time changes a person, how it changed Thranduil. And so, she wouldn't leave him, not for a thousand years, not even for a million. She would stay, like what she had promised the king.
Healing a broken heart wouldn't be easy. Healing the Elven King's broken heart was easier said than done.
But Faeryn was the best healer of Woodland Realm after all. Is there anything she cannot do?
