Who oversees Luna's invasion? She could be snooping and silencing those who have different views than the Diarchy. She also could be assisting in making ponies compliant with Cadence's power and now Twilight's. Twilight's image being representative of Friendship by the tree is now saying those who are not willing to accept our doctrine will be met with Rainbow Purifying/Stoning/Mooning power.



Luna being somepony who used it and was hit by it would make it to where she would make any and all subjects who disagreed with the friendship is magic idea then gets to endure that torment under the guise of "guarding from the nightmare".
