House Selmy of Harvest Hall is one of the principal noble houses from the Stormlands.
Its seat is Harvest Hall in the Dornish Marches. They blazon their arms with three stalks of yellow wheat on brown.
Ser Barristan Selmy, also known as "Barristan the Bold", is one of the greatest knights of the Kingsguard. Barristan is the eldest son of Ser Lyonel Selmy. He was in line to inherit the seat of House Selmy, but Barristan gave up his claim after he became a member of the Kingsguard. His cousin, who married the girl destined for Barristan, may also have taken over Barristan's claim to Harvest Hall.
At a tourney at Blackhaven, a ten-year old Barristan Selmy entered the lists as a mystery knight. He was eventually unhorsed and unmasked by Prince Duncan Targaryen, earning Barristan the nickname 'Bold'.
Barristan squired for Ser Manfred Swann and was knighted at 16 years old by King Aegon V Targaryen. Barristan was named to the Kingsguard when he was 23 years old and had the white cloak placed on his shoulders by Ser Gerold Hightower, Lord Commander of the Kingsguard. Barristan won a tourney held at Storm's End, beating Prince Rhaegar Targaryen in the final tilt. Barristan slew Maelys the Monstrous during the War of the Ninepenny Kings.
