For starters, I wasn't aware that Rarity was taken and second, my own characters aren't what you would call good and I like Rarity so why shouldn't I play as her for others that enjoy being around her? I would have liked to play Luna, best princess , but mother of Celestia! Those are some really big horse shoes to fill. I hardly think I'd ever be able to fill her role properly, even with lots of practice.
"I...I can't....I don't have any magic..." Spearmint said, feeling like he was about to cry. Even outside of the hive, he was useless. He couldn't do anything, at all. His head tilted down to look at the dirt. Small drops started to hit the dirt. Was...was he actually crying? He wanted to do what she was asking because the princess would be able to help him but he can't even do something as simple as going from one place to another.
It wasn't exactly like Spearmint had a choice. Yes, changelings normally only consume emotional energy from other ponies or from their queen. When expelled from a hive or having gotten lost somehow, there isn't any real way for a changeling to feed, so, all of them usually die from hunger. The only reason he didn't is because he learned how to feed from a different source. Its not as efficient or potent as another pony's emotions but no one gets hurt from it as a result.
He turns back to look at the old castle as the go outside. He was going to miss it, it was his home for about a year and a half. He took care of it as much as it took care of him. "Bye old friend..." he said quietly, seemingly behaving as if the castle was actually a living being. He zoned out for a bit, thinking back on his life before Midnight's question pulled him from his thoughts. "What? Oh...uhm...no. I never learned how to do that." He said, disappointingly. "Even if I did, I wouldn't be strong enough to hold the spell for more than a minute." He said, somewhat admitting that he has very little, if any, magical ability.
