In 2267, Mallory was part of a landing party of nine that surveyed the surface of planet Gamma Trianguli VI. After observing Vaal's civilization and constructs, the excited Mallory ran to inform his superiors. Mallory was unaware that Spock had discovered volatile explosives in the ground strata, and carelessly stepped on one such outcropping, dying from the blast.
