Yep she knew about trolls! Once upon a time a long time ago 9when she was ten) she'd seen one while visiting Romania. It was a guard troll and she'd never forgotten how scary it looked.

The rocks must have something to do with trolls then. Most trolls had grayish skin, just like these rocks. Hmmm.

Her hand shot into the air. "Trolls are able to speak some human words and phrases and can be taught a little, but they are still classified as beasts instead of beings by our Ministry due to how dangerous they are." Speaking of which, she had a question, but she'd not ask right away.
