- Father High Sparrow longed to purge the world of vice and sin. And he saw corruption everywhere, except within.”
- ―Jaime Lannister during "The Bells of King's Landing"
The High Sparrow is a ruthless Parisian justice minister who, after a series of sensitive circumstances, becomes the begrudged High Septon in King's Landing.
With a majority of the fifth and sixth season's heavy thematic elements being directly tied to the Sparrow's story arc — such as lust and genocide — he is widely considered to be amongst the darkest Game of Thrones villains of all time.
