Thankfully, their newest situation reunites them with Cici, the twelfth incarnation of Neas the Gladiator of Gallifrey. However, this version is not quite the same as the woman they first met. Newly regenerated, following a lost conflict among humans and machines, Cici must now find a way to save companions she has yet to meet, as well as time and reality itself, from the Terminators and their sworn enemies: the Cybermen!
