• Magnus Greel was introduced in the 1977 Fourth Doctor television story, The Talons of Weng-Chiang. He was a mutated despot from the future who fled to Victorian London in a Time Cabinet, along with his cyborg, Mr Sin. Under his Supreme Alliance, Greel was said to have killed 100,000, giving him the nickname, The Butcher of Brisbane.
• Time Agents were first mentioned in The Talons of Weng-Chiang, with Greel believing they may be after him. Beyond that, no other details are known about them. They weren't mentioned again in a television story until The Empty Child in 2005, when Captain Jack Harkness revealed himself to be a former Time Agent from the 51st century.

• In the Whovian timeline, this story takes place between The Jupiter Conjunction and The King’s Demons.
• Angus Wright played Mr Dread in The Sarah Jane Adventures story, The Vault of Secrets.

Doctor Who Magazine reviewer Matt Michael noted that the attempt to create a prequel to the well-regarded Talons of Weng-Chiang was "brave", but found the effort successful.^[1]
