Lucius was a young member of the infamous Ninth Legion, which vanished without trace in the Highlands of Scotland. The culprit was a savage creature known as an Eater of Light, which resided in an alternative dimension - accessed via a Pictish temple. A girl named Kar had freed this, and now she did not know how to control it. It began feeding on everyone - Roman and Pict. Lucius explained to the Doctor's companion Bill that his colleagues were all young and terrified. When the Doctor offered to sacrifice himself to keep the Eater confined, Lucius and Kar joined forces and agreed to take his place. The other dimension ran to a shorter time-scale, so they were still alive and battling the monsters in the early 21st Century.
