Pek was a martial art practiced by the mirror universe counterparts of the Ferengi. This technique relied on the remarkable auditory and mathematical capabilities of the Ferengi. It operated by predicting the moves of their opponents through a combination of listening to the air and triangulating the attack of their foe. Among the key practitioners of this fighting style were the Zakrim assassin cadre. (Decipher RPG module: Through a Glass, Darkly)
