There's a spell that is as old as time, but only a few alive today know of it's existence. It's rumored to have been created in the time of Merlin, but those are rumors, no one knows where it came from or whom it was made by. It's called Imperio Imperfecta, a spell branched off of the famous Imperius curse that is still used by witches and wizards today. The Imperius curse used today, when used properly, will make the victim fall under complete control against their will to the wizard who casted it. For example if the caster told his victim to jump off a building, he would have no other choice to, unless his will is strong enough to resist the spell. While the Imperius can be broken, the Imperio Imperfecta can not be broken, unless the victim is released. Imperio Imperfecta is translated to Imperfect Empires, which for the spells use is perfect title for it. Like the Imperius curse, Imperfecta Imperio, lets the caster have control over their victim but not complete control. The victim while under this curse has control of their thoughts and feelings, but has in a way complete obedience to the caster of the spell. This spell is used by husband in pureblood households, to make sure their wives are obeying their wishes and supporting them when it's the last thing they want to do. It's a complex spell that can be used in different ways all based off the idea of obedient control over the husband's wives. Confused? I told you it was a complex spell, let me explain it in another way, by telling a story of an unlikely couple and his use of the Imperius Imperfecta.
