The Ogri were killer stones from the planet Ogros. They drained the blood from their victims and stood in a druidic circle in the English countryside. The Cessair of Diplos illegally removed the Ogri from their home planet and used them as guards. The Ogri are another Doctor Who monster that is ripe for a return to the show.

The Fourth Doctor and Romana’s search for the third segment to the Key to Time takes them to a stone circle in the English countryside. Professor Emilia Rumford is conducting a survey of the stones along with her assistant Vivien Fay. At a nearby Manor House, the Doctor meets Mr De Vries, who is part of a druidic cult that regards the stones as sacred. Romana is almost killed before she is rescued from a cliff face by the Doctor. Romana and the Doctor discover that the paintings in Mr De Vries’s mansion have been concealed because they all contain the same woman: Vivien Fay. Ms. Fay is not who she says she is! Ms Fay is actually an alien criminal called the Cessair of Diplos, and the stones in the circle are her guards: the Ogri. The Ogri were illegally taken from the planet Ogros by the Cessair of Diplos. The Ogri are killer stones that suck people’s blood and drain them till only their skeletons remain. The Doctor finds that Ms. Fay’s spaceship is suspended in hyperspace above the stone circle. Onboard the ship, the Doctor and Romana meet the Megara – justice machines that judge, try and execute criminals with shocking swiftness! The Doctor tries to convince the Megara that Ms. Fay is the Cessair of Diplos, the criminal that they are searching for. After much evidence, the Megara finally realise that the Doctor is telling the truth. Ms. Fay is captured by the Megara and the Doctor removes her necklace which is the third segment to the Key to Time in disguise. The Cessair of Diplos is turned into stone as part of her sentence. The Doctor and Romana depart in the TARDIS, leaving Professor Rumford to her study of the stone circle.
