Cornelius (The Eaters of Light)

Cornelius was a Roman soldier who accompanied the Ninth Legion as they invaded Scotland.

Biography
Cornelius was part of the Ninth Legion when they invaded the area of Aberdeen in the 2nd century. The legion was attacked by a creature known as the Eater of Light. Cornelius and a small group of others ran from the beast, while the eldest members of the legion were all killed by total absence of light.

The group hid in a cave, while Simon was sent in search of a road south. He never returned. Instead, Lucius encountered Bill Potts who was trying to escape from the Eater of Light. He and his legion pulled her into the cave and blocked up the entrance. Bill collapsed.

Forging an alliance
Two days later, Bill had awoken. She had been lashed by the beast as she entered the cave and had thick black slime on her neck. She was advised to stay in the sunlight, knowing that it would burn off the slime.

Bill told the Romans about the Doctor. After Lucius had agreed to find him, Cornelius, Bill and the rest of the legion followed Vitus through the labyrinth of tunnels to the Pictish community. Below the Pict's roundhouse, the Legion witnessed Cornelius being attacked and killed by an Eater of Light.
