Faramir was given his first sword so long ago he doesn't remember not owning one and while he was at first much more interested in his books than in weaponry it was not long before the influence of his adored brother began to set in. Boromir is ten years his senior and Faramir has spent the entirety of his sixteen years thinking his brother a god.
In some ways the two could not seem more different even though they look so much alike. Even as children it was so. As Boromir sat beside their father Denethor in court and eagerly learned from the citadel guard all he could discover and some things he shouldn't have repeated, Faramir spent his time following the keeper of Gondor's ancient library and doing odd jobs for the Wardens of the Houses of Healing. He was at his father's knee only to ask for answers and stories rather than to absorb and adopt the ways of the ruler. By the time the brothers were eight and eighteen Boromir had picked up many mannerisms of their father and commanded his first expeditions with a tone and mind very familiar to the men in his service. Faramir was said to resemble his mother or neither parent in his shy nature and his willingness to listen to any snippet of lore or history that someone would tell him.
So it startled a few of his tutors and the servants of the house when at thirteen quiet, bookish Faramir began challenging Boromir to practice swordsmanship with him. Boromir indulged him and Faramir always lost.
But he persevered and refused when Boromir kept offering to go easy on him. He learned more from the losing than he would have from a swordsman of his own ability and soon that ability was greatly expanded. Their illmatched practice never seemed to draw more than half curious glances from Denethor, but Boromir's laughter and the rough hand ruffling Faramir's hair – those gave the boy a warm, steady glow that no other's praise and no other's touch could equal.
Now that he is uprooted from home and far from the warmth of his brother's love and the long-held hope of his father's approval, Faramir carries his sword close by him even though he's already noticed that very few in this place go armed. Its weight at his side is comforting as he pushes into the Pub having come on Mina's recommendation. Here in this strange and frightening place it is a touch of home and a memory of his brother that he cannot imagine doing without.
