Duncan the Tall was a Hedge Knight. Raised as Dunk in Flea Bottom, Duncan became the squire of the hedge knight Arlan of Pennytree. Duncan then traveled the Seven Kingdoms as a hedge knight himself, with the young Prince Aegon Targaryen, called "Egg", as his squire. The early exploits of "Dunk and Egg" are chronicled in A Knight of the Seven Kingdoms, which collects The Hedge Knight, The Sworn Sword, and The Mystery Knight.

In the television adaptation A Knight of the Seven Kingdoms, Duncan is portrayed by Peter Claffey.

Duncan is an inch shy of seven feet tall.[1][3] He has thick, shaggy hair, that is sun-streaked in the summer.[2][3] After the events at Standfast in 211 AC, he has a dagger scar on his cheek.[2][3] Dunk is strong and quick,[1] and has been taught jousting and swordplay.[1] He is better with a sword than with a lance,[3] and even better with an axe or mace.[2]

Duncan has a humble personality, and frequently thinks of himself as thick-headed, recalling how Ser Arlan had often said "Dunk the lunk, thick as a castle wall", and referred to him as "slow as an aurochs"

Duncan's earliest memories were of living as a street urchin in the Flea Bottom slums of King's Landing.[1] His closest friends went by the names of Ferret, Rafe, and Pudding. By his own admission, they were "little monsters" with Duncan, at the time still known as "Dunk", the worst of all.[3] Sometimes they would sell[2] or even dump[3] pieces of meat of dubious origin to the local pot shops that made the bowls of brown.

Duncan was an orphan,[1] and never knew either of his parents.[2] It may be that he is a bastard.[2] He believed his father might have been a criminal, and once hoped to someday go to the north and eventually the Wall, where he could perhaps meet some tall old man who looked like him.[2] The hedge knight Arlan of Pennytree took Duncan as his new squire about two years[N 1] after the death of his previous squire, Roger of Pennytree, during the final battle of the First Blackfyre Rebellion in 196 AC.[2] He found the young Duncan, aged five or six,[1] in King's Landing chasing a pig and took him on.[3] He raised Duncan and together they traveled all over Westeros, except the north.[2] Though they never visited Pennytree, where Arlan was from,[3] they served Lord Leo Tyrell at Highgarden during one of the first few years that Duncan served Ser Arlan,[1] visited King's Landing in 205 AC,[3] served Lord Florent for half a year and joined Lord Dondarrion in the hunt for the Vulture King, both in 206 AC,[1] and visited Lannisport in 208 AC,[1] amongst other places. As well, Duncan accompanied Arlan when he was one of several knights hired by a Dornish merchant who wanted to travel from Lannisport to the Prince's Pass in Dorne.[2]

Duncan learned sword-fighting from Ser Arlan,[1] though he still recalls his fighting experience from Flea Bottom as well.[1][2] Ever since the first time that Arlan had let Duncan hold a sword, Duncan had dreamt of becoming a Kingsguard knight.[3]

Because Dunk grew up as an abandoned orphan in the streets of King's Landing he wasn't sure exactly how old he was, and his unusually large height from a young age made it difficult to guess. By 209 AC he loosely thought he must be about 19 or 20 years old, which would place his birth somewhere between 191 to 193 AC.[1]

In 209 AC, a tourney was to be held at Ashford. Arlan died on the way to Ashford, and after Duncan had buried him, he decided to compete in the tourney at Ashford Meadow in Arlan's stead. On the way he stopped at an inn. Inside, Duncan met a drunken man who claimed to have dreamed about Duncan, and who became distraught at the sight of him. Duncan also met a bald-headed boy, who begged him to be allowed to become Duncan's squire when Duncan left. Duncan refused, left, and shortly thereafter arrived at Ashford. Duncan made camp, and that evening discovered the bald boy from the inn at his camp, who claimed to be called "Egg" and said he came from King's Landing, causing Duncan to believe the boy is an orphan from Flea Bottom, just like Duncan had been. Because he does not have a squire, Duncan accepted Egg as his squire for the duration of the tourney.

Once at the tourney grounds, Duncan is forced to sell Sweetfoot, one of his horses, and Ser Arlan's old armor, in order to be able to acquire armor of his own. He met a puppeteer named Tanselle, who agreed to paint his shield with his personal sigil.[1] The day after his arrival, Duncan went to register for the tourney. Knighthood was required for participation in the tourney, and Duncan told Lord Ashford's steward how Ser Arlan had knighted him before his death.

Duncan is an omega. People in this world are either Alpha, Beta, Or Omega. An alpha is someone born with animalistic dominant genes, and normally someone strong and fierce. Alphas need omegas to breed, and mate with omegas for life. To mark an omega, they bite them to claim them. All alphas go into a rut once a month where they are insatiable and need to breed an Omega. All alphas have a cock that swells up and knots to lock them inside an Omega during climax. All alphas have sharp incisor teeth, needed to mark an omega with something called a 'claiming bite'. An omega is someone born with animalistic submissive genes, and normally someone that can give birth. Male Omegas are rare and can still get pregnant and give birth. Omegas mate for life with an alpha, typically anyhow. Omegas go into a heat once a month and release pheromones that attract alphas and cause alphas to go into a rut. Omegas have nesting and mothering instincts. Omegas release slick when aroused by an alpha. Betas are a neutral gender that has neither dominant nor submissive traits and does not go into heat or rut. Betas are the most common.
