Petyr Baelish, nicknamed Littlefinger, is a fictional character in the "A Song of Ice and Fire" series of fantasy novels by American author George R. R. Martin, and its television adaptation "Game of Thrones". Introduced in 1996's "A Game of Thrones", Littlefinger is the master of coin on King Robert's small council. He is a childhood friend of Catelyn Stark, having grown up with her and her two siblings at Riverrun. He subsequently appeared in Martin's books "A Clash of Kings" (1998), "A Storm of Swords" (2000), and "A Feast for Crows" (2005). He is set to appear in the forthcoming novel "The Winds of Winter". Littlefinger's primary character attributes are his cunning and boundless ambition. Originally hailing from a minor family with little wealth or influence, Baelish used manipulation, bribery, and the connections he secured at Riverrun to gain power and prestige in King's Landing. Since then, his various intrigues have directly caused several major events that have impacted Westeros, including the framing of Tyrion Lannister for the attempt on Bran Stark's life, the downfall of Lord Eddard Stark, the deaths of Lord Jon Arryn and King Joffrey Baratheon, and the War of the Five Kings.
