Josef was a resident of Trenzalore roughly 300 years into the Eleventh Doctor's stay on the planet. He was a member of the Lifeboat crew and assisted the Doctor in sailing to the Outland to find the threat that had invaded Trenzalore and murdered Tiberius Gluck. He helped Jerema load Tiberius's remains onto the Lifeboat. (PROSE: Strangers in the Outland)
