"scales" - ecthelion of the fountain
He thinks of his father’s words to him in Alqualondë before the Flight (oh, or fight) and wonders abstractly what wisdom he would pass on to his own children. His sword is still sharp. He would tell them to practise their scales every day, every single day. He may have taken a blow to the head, helmet or not. He would tell them not to take themselves too seriously. His arm is aching, probably broken. He would tell them that they will make him proud.
(But, oh, these children do not exist, or that wife, for Ecthelion of the Fountain.)
