During the final days of the 1st Captain, he must fight the Guardian of Darkness and Chaos, who is one of the Six Guardians of the Higher Dimensions (and is also one of the Great Old Ones). The Guardian of Darkness and Chaos (Black Guardian) has come from the 7th Dimension to the 3rd Dimension to stop the Captain from continuing to bring back the Time Lords.
The Captain decides that him and the new Time Lords must fight to protect themselves and Ardethe. He even takes off his upgraded hand, knowing that the old robotic one is technically better. But can the Captain save his people and his new home? Or will Ardethe and the new Time Lords fall with him?
