Arnvarius

A Dalek-invaded planet was one of the locations where Bel sought refuge after her home planet was ravaged by the Flux. It was located in a region of space that Bel nicknamed the Dalek Sector. (TV: Once, Upon Time)

Behind the scenes

 * While the planet is left unnamed in Once, Upon Time, the shooting script found on the BBC Writers Room's gives the planet's name as Arnvarius.


 * The shot of Arnvarius viewed from space appears to be a flipped and colour swapped reuse of a shot of the planet of Ranskoor Av Kolos from The Battle of Ranskoor Av Kolos.
