Heeeeeyyyy, you made it!
Yep. And, after a night to think about it, I think I have a concept.
Miranda is the daughter of two very prominent (and very powerful) heroes, which is part of why she's currently being mentored now. She is highly trained in all the skills a good hero needs; martial arts, stealth, athletics, and investigation. Only one problem at the moment.
She hasn't manifested any powers.
Don't get me wrong, she WANTS to manifest. Her parents want her to manifest. It just appears that her genes are stubbornly refusing. That's the other part of why she's here; to try and coax her into developing powers.
Trick is, she HAS manifested. It's just that her powers are so subtle that no one around suspects them. Things just seem to go her way. Granted, this does not mean that she lives a charmed life; she might discover the one clue needed to crack a difficult case by literally tripping over it, she narrowly avoids getting hit in the head from a sniper by tripping and spraining her ankle, and so forth. Think Marvel's Black Cat, but she's not aware of the ability.
Her secret, personality, etc. I will PM to Xer later today. Right now, I need to come up with a code name.
