What might her cutie mark actually mean?

I think we can agree that it has something to do with flying, due to the "Glider" part in her name and her pretty good aerial performance in chasing Starlight.

The crescent moon mark points to night or perhaps the stellar body itself.
What I would really like is her being the Equestrian version of Neil Armstrong who will become the first pony on the moon.
I know that this is a bit unlikely given the technology level, but hell, a lot can happen with magitech. She would also be a prime candidate should a space agency be opened, since the NASA also primarily recruited traditional pilots in the early days.

What are your thoughts on potential talents/ obligations?

A pony interested in space sounds like it would be a good fit, given the moon portion of her cutie mark.

However, we already have another thread like it, which can be found by clicking here. Just so that we don't have redundant threads popping all over the place when similar/identical threads are still technically active, I'm going to have to lock this. Sorry about that.
