what's a grocko? is it another word for alligator, or an alligator-like creature or what? my first thought was that it was slang, but dahlia doesn't seem like a slang-user and she prob wouldn't be familar w local slang anyway. or would she? how long's she been in the area (if that's not a spoiler)
It's just a type of gator-like dragon. And off the top of my head I'm not sure how long she's been in the area yet, I want to say a month or so.
