Freya raised her hand yet again, "The unforgivable curses would be the Imperius curse, the Cruciatus curse, and the Killing curse. The imperius curse is used in order to control another human being or animal in order to have them behave in a way they normally would not. The curse makes it relatively easy to penetrate security and retrieve information from unwilling parties. The Cruciatus curse delivers a crippling blow of pain to the victim, often resulting in the loss of movement and if used excessively can deliver such a shock that the person will eventually collapse or suffer from psychological damages. The killing curse is used for the exact reason it is named, to kill another living being." Freya didn't dare say the incantation for the last curse, just the thought of that green light coming out of her wand was unpleasant. And with the way her wand had been acting, it wouldn't entirely surprise her either.
