Sheprah was an officer in the Vogan military.
Following the outbreak of the Vogan Civil War, Sheprah commanded Tyrum's forces as they tried to force Vorus' men out of the gold mines. He had a group of Vogans who were pursuing Sarah Jane Smith and Harry Sullivan surrounded, forcing them to surrender. Sheprah captured Kellman when he arrived on Voga and took him to Tyrum.
When the Cybermen invaded, Sheprah led the defence. However, this had no effect as the Cybermen were immune to Vogan weapons and soon Sheprah found that his men refused to fight. (TV: Revenge of the Cybermen)
