Tiestus was a 22nd century human colony planet. Capitol City was the planet's capital city. In 2114, Morris was its president.
In July 2114, weapons-grade Cybermen invaded Tiestus and attempted to convert its population. Humans were rounded up by the Cybermen and taken to a warehouse which had been adapted into a cyber-conversion factory. The invasion was stopped when Jacob Sowersby used his BOB implant to interfere with Cybercontrol and overload the Cybermen with emotion.
