Yevgeni Cento

Yevgeni Cento is a Lothrian geneticist operating Cento Biotechnic on March Station, notable for a machine eye implant and one visibly regrown hand. He serves as a minor but pivotal contact in Hadrian's search for Vorgossos, explaining that access to the planet runs through the Exalted and directing Hadrian toward the docks.

Cento's referral leads Hadrian to the ship captain Antonius Brevon, who recognizes Cento immediately by the nickname "the little cyclops" -- suggesting Cento is a known figure in the margins of interstellar trade on March Station.
