Calbaron III

Calbaron III was a planet which during the 51st century was ruled by the tyrannical emperor Vimlox. In 5083, Vimlox was overthrown. In the same year, the Twelfth Doctor and Clara attempted to reserve a table at a restaurant. After being told they would have to wait three years, the pair returned in 5086, only to find the restuarant closed. They then travelled back in time to 5080 to book a table for their original arrival time. On this visit the Doctor noticed his TARDIS had been scratched, and after discovering this had been done by the emperor Vimlox the Doctor decided to overthrow him. (COMIC: Planet of the Diners)
