Based on Letters from an Irritated Princess by Tired Old Man, written in the same format, with the same sort of thing going on more or less, but, with said letters written by the Evil Empress, Daybreaker herself, instead of her goody-goody counterpart. Permission for this was given to me by Tired Old Man himself!
Ah, letters. To some, letters are a means for friendly, long distance communication. To others, they are a way of informing you that you are late on your monthly payment. But, for Empress Daybreaker? Well, they're a way of expressing displeasure, annoyance, evil amusement, ransom demands, and other things.
Basically, they're for making her subjects twitch in fear. Lots of fear. Whether it be of her wrath, or the horrors her evil mischieviousness will bring to her subjects.
