Volk
One of the "Original Dozen," the first colonists to arrive on Mars, Volk's life has been greatly extended by science. Ruler and representative gladiator of Volk City, he is the closest thing to an overall ruler Mars has, and it was he who chose to destroy the refugee ship on which a young Layla was a passenger. He feels his responsibility very deeply, and takes every action for the greater good of Mars and its people. Their well-being is his greatest concern, and he will commit whatever sin he has to in order to ensure it. [from Wikipedia].
