But even if you become so far gone that you forget your own name, you will remember this: That this is your punishment, and that you forced my hand.
You are a fairy. Not the sissy "fairy dust and granted wishes" style of fairy, but the old school kind of fairy that people only called "fair" as a form of appeasement. Or at least, you were. Now you suppose you're really the "runs away from everything like a sissy" kind of fairy, if that even exists.
You have severe amnesia, remembering very little of anything that happened more than a week or two in the past (and even have gaps there). However, unlike most people with missing memories, you know exactly why it happens, what triggers it, and even how you can get it back. She made very sure of that. You suppose that was probably the point.
Let's start over. In this land fairies are considered by far the most dangerous of monsters, because every one is born with a special power. Yours was one of the strongest out there--the ability to control memory. With finesse you could rewrite the innards of someone's brain until they believed themselves to be a trusted ally, a loyal servant, or just until they believed they already wanted to do whatever you wanted them to do. You used it quite liberally and gained quite a reputation. However, at some point you pissed off a fairy even more powerful than yourself, and she afflicted you with a terrible curse--your powers remained, but not without severe backlash. If you erased or rewrote anyone's memory you would lose a proportional ammount of your own memories, and if you read somebody's memories they read a proportional ammount of yours. You could get something back by restoring lost or altered memories in others, but the only people who ever forget enough to be useful are your own past victims, and most of them are a bit hostile afterwards. So your time since being cursed has mostly been a downward spiral, losing a little more every time you need to defend yourself.
Of course, you haven't become so far gone as to forget your own name. Yet. What was your name again?
