Peggy Marsden

 was the husband of Albert Marsden. In an alternate timeline that became a pocket universe, the pair of them were inhabited by a pair of Elder Gods who served Moloch.

Prime timeline
In the prime timeline, Peggy was seen to offer Albert a cup of tea, while Albert remarked upon the roses he had been planting in their garden. They also had a son called Raymond. The Seventh Doctor showed the Elder gods in the pocket universe the life that Albert and Peggy lived in the original timeline. (AUDIO: Protect and Survive)

Alternate timeline
In an alternate 1989, Albert and Peggy died in November 1989 after a Russian nuclear warhead was detonated near their location in the United Kingdom. Such an event had been anticipated, so the pair of them had worked to build a fallout shelter as per the Protect and Survive pamphlets, however it was not enough to save them. (AUDIO: Protect and Survive)

Pocket dimension
The alternate timeline was eventually compressed into a five mile area with just the two of them, in a pocket universe where their bodies were inhabited by two Elder Gods, after the Seventh Doctor tricked them. The two Elder Gods inhabited their bodies for over a century, living through their last 10 days in November 1989 over and over again. Finally, the Elder Gods met Ace and Hex, whereupon they escaped, with help from Moloch. (AUDIO: Protect and Survive)

She later met Sally Morgan and Lysandra Aristedes coming out of Weyland's Smithy, an ancient burial ground. She was sent for by Weyland, after Fenric played an illegal move, showing them their future. She mentioned that she liked tea in the cup and mentioned her husband. She discussed the opponent of Fenric, someone with the power to move people through time and space, and can talk people into dying for him. After Moloch saved her from the Doctor's previous trap, Albert was used as a hostage so that she would do Weyland's bidding. She stole Weyland's Shield from Lysandra Aristedes, to give it to Weyland in return for Albert, so he killed them both. (AUDIO: Gods and Monsters)
