In a land somewhere, there once was a warrior prince known for leagues for his great battle prowess and tactical ability. Due to his many successes, unfortunately, he eventually became very arrogant. Though he was still greatly respected for his abilities throughout the land, those who came close to him often found him difficult to deal with due to his egotistical behavior. 

It was only a matter of time, but at some point, he ended up disrespecting the wrong person. This person happened to be a powerful practitioner of magic, and cursed him in the hope of teaching the prince a lesson. Instead of the warrior male he was known to be, the prideful youth was transformed into a slight young girl. This wouldn't have been so much of a problem to him, had he not also been struck with a frailty that granted more physical difficulties than any normal human should ever have. The prince could hardly even lift a sword anymore, much less cut someone up with one. 
Shortly after, the troops he was on a campaign with were ambushed, and the prince barely escaped with her life.

Once upon a time, there was a prince of a distant kingdom. He was hunting in the woods with his men one day when the weather threatened to turn foul, so the group turned for home. Long before they got back, though, they came upon a young girl, terribly injured and unconscious in the woods. Concerned at her critical condition and the oncoming storm, the prince decided to bring the girl back to the castle, where he made sure that she was carefully cared for. 
When the girl awoke, he was delighted, and upon questioning, she told him that she was the offspring of another kingdom's ruler. After a while, the prince found himself quite taken with the girl, but the queen of this kingdom remained suspicious of the oddly unladylike mannerisms and clothing she had displayed upon showing up at the castle. Eventually, she devised a plan to see whether the strange girl really was royalty or not. When the girl was eventually able to leave the room for a while, the queen had a single pea placed under the many mattresses of the bed. 

That night, perhaps because of her newly oversensitive skin that she was still getting used to, the girl found herself having quite a bit of trouble sleeping. In the morning, forgetting her manners for a minute, she complained about the difficult night she'd had during conversation with the queen and blamed the mattress for being uncomfortable. Instead of the rebukes she had expected, the girl was quite confused and pleasantly surprised when the queen actually praised her. At least, until the queen told her that she wanted the girl to marry her son. The girl panicked and refused, but the queen would have none of it, insisting that, for some reason, that test had proved her to be the perfect candidate for the woman's daughter-in-law. 

The wedding was arranged between the prince and the unfortunate girl, but merely three days before the ceremony, the girl suddenly vanished. 

The prince, still somehow very attached to the idea of marrying her, is said to still search for the girl. Where exactly she went to, though, nobody is certain. 

...But that curse needed a cure.
