Benjen Tyrell was the youngest trueborn son of Baelor Tyrell. He was slain by his brother Troy Tyrell at the command of Ser Thaddius Lannister along the road to King's Landing after being taken hostage.
Benjen was born and raised at Highgarden in the Reach, and trained at arms from an early age. He was known to have a cruel streak and a short temper.
Benjen was captured by Thaddius Lannister, along with his brother Troy Tyrell and his sister Mellara Tyrell outside of Oldtown. While being escorted to the capital, Troy killed Benjen after they were forced to fight to death.
