I am the second son of a Marquis of Hyrule, ruling over one of the border-marches of Hyrule (my older brother has already taken the title + had kids, so major inheritance is extremely unlikely). Childhood consisted of being polite to guests, page work and sneaking away to learn smithing. Joined the knights out of a sense of duty (my family expected that kind of thing from me, and I had the aptitude for it). Served as a cataphract for a number of years, earning a number of honours. When my brother had kids, my family lost interest in me somewhat; I was no longer needed as a spare. Between this, and me earned titles, I secured to right to leave my order and wander the land searching for objects of interest related to the hero of legend (or any of the other ancient myths of Hyrule). If my family (or my country) had need of me, I would go, but I bring enough honour and glory through my work that they let me be. Duty and Tradition matter to me, but I am aware that part of the traditions I uphold involve cunning and improvisation, so I seek to also learn those lessons.
I appear as a man in his late 20's or early 30's with pale skin, the pointed ears of a true Hylian, a short beard and the slightly lopsided look of a blacksmith, wearing heavy armour and riding a chestnut horse swathed in chain mail. My lack of blatantly magical weaponry is surprising, given my status; I hold a lance and a long riders shield with the logo of the Hylian knights upon it, and have a number of weapons at my belt, and a tremendously heavy composite bow on my back. My horse is more magical than I, in some ways; it's eyes sparkle with uncanny intelligence, and it's legs are sheathed in glowing blue armour. I will happily describe it's peerless pedigree to any who will listen - it includes the mount of the last hero of legend, among other, more ephemeral sources. It was a gift from when I first received my knighthood; It's owner said it had chosen me; and we all know that proverb about gift horses.
My gear is, astoundingly for such works, mostly handmade (which I didn't take a discount for). The most noteworthy exception is the riverine dagger; an indestructible artifact that has been passed down in my family. My Gauntlets of Ogre strength are the product of a house enchanter, who wishes to see them added to the family panoply in time. I have a number of other minor items, some (like the hand of the mage and the rust monster wand) retrieved from previous dungeons, while others (the minor alchemical ones, among others), purchased out of my purse just in case. My Haversack was a "retirement" gift from my unit (who, being mostly aristocratic themselves, could easily afford such a thing), and is inscribed with the logo of the hylian knights across it's back, to match my shield.
At the start of the game, I am wandering. I seek companions in my journey. The precise details of where I am and what my goals are depend on the plot at hand.
Also, what languages would be appropriate for a Hylian aristocrat to know?
