Wane breathed in and out, then glanced again at the Guard. He had found that he looked more tired than stern. Granted, his own sleep schedule was rather erratic, since he found work during the day and spent some of the night researching. Then he looked again. Another bat pony. He grinned, as he replied,
"Uh, yeah. Well, I was just on a quick flight, but I actually have a few questions for you-"
He held his forelegs out, the glow now like moonlight on silver. The glow gently fluctuated.
"By any chance, have you ever seen others with these marks? I was told a while back that Ponyville was a magnet for strange magical... things. I've trying for ages to get an audience with Princess Twilight for her insight, but I could swear she's always on the move around Equestria. So, until I can get an audience, I've been making do with asking ponies-"
His ears twitched, then flopped down, along with a slightly apologetic look.
"Err, sorry. Sometimes I get a little carried away. it's just that I've been trying to figure out these... tattoos? Glyphs? I'm not certain what to call them. I've had them since birth, and I've had the theory that they could be related to cutie mark magic. Seeing that her Highness is well versed in such concepts, I thought that it would be prudent for me to speak with her."
He shuffled on his hooves.
"So yeah, have you ever seen anything like these?"
