Brave Twins

Merida and Erin are inseparable, despite their constant bickering. They are always together, they share a room, and the last time they were separated they were crying when they reunited. Really, to be completely honest, it was dangerous to separate them. Merida's temper got out of control, and Erin's bad habit of being /extremely/ passive aggressive came out. If it was separation for duty, it was okay, and they were just a bit calmer. But more often than not, it was just to separate them, their parents trying to prepare them for the day that was coming up where they would be separated... Forever.
And that day's come, now. The suitors have accepted, and Erin, the youngest, is being sold off to whomever is to win her. But Merida isn't having it. She doesn't want her sister taken from her. And even if she had to shatter tradition and change both their fates, she's going to make sure they stay together, and won't be separated. Even if it changes her.
