Prerequisite: Time Lord

The Time Lord has had their Imprimatur removed or never developed it. This may be due to their relative youth, damage sustained in the Time War or its surgical removal (Ingenuity + Medicine, Difficulty 30). Regardless, the Time Lord cannot connect with their TARDIS and must find another way to ensure safe travel or, worse, another time machine. They can develop more over time (the Nuclei reform every regeneration at least) or they can receive a transfusion from another Time Lord (Ingenuity + Medicine, Difficulty 23)
