Hmmm... that was something she'd have to look into. Magic was 'alive' in a sense, but she'd never seen sentient behavior from things like rocks before. Maybe it was something to do with the magic here, but she'd have to be cautious. She didn't like the idea of hurting a 'person' after all, then again, it sounded like he's the catalyst, so perhaps he was 'translating' magic into something he could interact with...

She resists the urge to automatically correct him calling her a 'horse' with a horn, mostly because how would he know? Still, she would explain "Hmmm... I'm a unicorn, technically a pony with a horn, not a horse, if you want to try and be specific..." She nickers softly "Oh, it's not enough about you, not by a long shot. I've never met anyone that can talk to spirits before."

Trixie was curious. This place was so interesting... Nobody was going to believe this when she went back to Equestria, then again, maybe she wouldn't share this discovery. Call her paranoid, bit she'd rather Discord not have access to such a place.
