Operation: Mecha

Operation: Mecha is a secret plan from House Lannister to turn every citizen of King's Landing, and eventually Westeros and then the world, into robotic slaves for the Lannisters, using a robotization technique called 'Robotol' which would give the Lannisters complete control over every robot they created. In theory, the Lannisters would be able to make the robots do whatever they wanted, whether the robot themselves wanted it or not. Every member of House Lannister was told about the plot, except for Tyrion, who Tywin regarded as untrustworthy.

Eventually, thanks to Petyr Baelish spying on important Lannister conversations, Operation: Mecha was discovered. Petyr and Tyrion then freed Arya Stark, who Cersei has kidnapped to be the prototype for a Operation: Mecha test. Cersei continued with testing, but Operation: Mecha is still nowhere near complete.

In the meantime, Baelish and Tyrion have created a group called Anti-Robotol which they operate from Winterfell. Together they intend to stop Operation: Mecha for good.
