House Tyrell

House Tyrell of Highgarden is a Great House of Westeros. It rules over the Reach, a vast, fertile, and heavily-populated region of southwestern Westeros, from their castle-seat of Highgarden as Lords Paramount of the Reach and Wardens of the South after taking control of the region from House Gardener during the Targaryen conquest.

The House was formerly led by Lord Mace Tyrell. Mace's son Loras was a noted tournament knight and, secretly, the lover of Lord Renly Baratheon. Mace's daughter Margaery married Renly when Stannis crowned himself king in the War of the Three Kings to cement an alliance between Renly and her father. Following Renly's death, Margaery was then married to King Joffrey Baratheon before his assassination at his wedding feast.

Due to the death of his father, Willas Tyrell is the new head of the house.
