"While not a master at any one skill, Rook showed an amazing proficiency in a wide variety of encounters. Its consistently solid performance was what made Rook such a threat in battles. No matter the scenario, the warrior was able to maintain focus and complete its mission. Rook's handle was given to it by Lt. Mikhail Tolten, the chessloving pilot who would eventually take out this ace, for the Vanduul's no-frills flying and ability to control the field of engagement."
