A geologist pony I've had around for a couple of years now. She's from the volcanic plains of Equestria over by the dragon lands and tracks earthquake activity for a living.

She's also a raging nerd and very much an "UMM ACKCHUALLY ☝🤓" species of turbo-virgin scientist, but she's funny in the dry sarcastic way and very excited to talk about quartz with you if you give the slightest ounce of interest.
