Private Rook is a Ranger stationed at the Ranger Citadel.
The youngest of seven children on his parents' farm, the 25 year old Rook had to fight for respect daily. His scrappy, underdog attitude became a great asset when he went out to seek his fortune in the wastes. He's an excellent shot with a carbine. Aberforth, a goat wandering nearby, appears to be well liked by Rook.
Rook can be recruited if the player has less than four Rangers in their party. However, if the player kills Aberforth, Rook will refuse to join the player's party, instead angrily berating the player.
