Mabli vestai Galann

Mabli of House Galann was a Force Leader in the Klingon Marines. In 2233 he played a game of Klin zha kinta against Thought Admiral Kethas, but secretly used a cybernetically-enhanced Lancer. When Vrenn defeated this Lancer, exposing Mabli's cheating, Mabli was killed by General Margon. (TOS novel: The Final Reflection)
