Lam Leahru-Mar was a male Naxeran pilot in the early 24th century. He had at least one sister, and a nephew, Pahl. In 2336, Mar and his (unnamed) ship were hired by Su Chen-Mai for a mission to an unnamed planet near the Cardassian border to find a legendary interdimensional portal. When his nephew became possessed by a non-corporeal lifeform on the planet, he attempted to defy Chen-Mai and take the boy with him aboard the USS Enterprise, the Federation ship that had been led to the planet by another party. Chen-Mai reacted by shooting Mar dead with a phaser. (TLE novel: Well of Souls)
