Sevcheria
From Tardis Wiki, the free Doctor Who reference
Sevcheria was a slave trader in Rome. He and his partner Didius captured Ian Chesterton and Barbara Wright. He sold Ian to a buyer, and Barbara to Tavius.
He later travelled to Rome and arranged the gladiatorial fight between Ian and Delos for Nero. Nero then had Sevcheria command the security at the Imperial Palace to catch Ian. Sevcheria was killed by Delos when Delos shoved a burning torch into the slave trader's face. (TV: The Romans)
