You’re right, the Hogwarts wards don’t detect or prevent Imperius cast by and on professors. That actually makes sense to add extra deniability for Quirrel (or whoever is controlling them). Edit: either I didn’t see this part of the grandparent or I didn’t realize the implications.
However, either the Imperius must be maintained indefinitely: too much risk of being found out one day? If something happens to the controlling character, short of death, does it provoke a Will save and break the Imperius? If the controlled character is examined, especially by a Legilemens, the Imperius would definitely be found out but would the controller be identified? Does someone being controlled necessarily know who the controller is?
Or it would be maintained for only brief periods, each time erasing the target’s memory of being controlled.
Note 1: Lucius claims to have been Imperiused for years by Voldemort with at least some plausibility, so presumably all of this is surmountable.
Note 2: an Imperiused professor could be ordered to self-erase memories after each time they executed orders from the controller, so the two don’t even need to meet to coordinate (pure mental control).
This looks like a game-breaking spell. A very powerful wizard who has infiltrated the enemy camp should carry out all of his actions via Imperiused agents. Are there any limitations? For instance, does maintaining an Imperius take up a piece of the controller’s magic for the duration? How does one break it if one has captured a controlled piece but cannot face the controller directly? Inquiring minds want to know :-)
