Earthquakes weren't something that Jon was familiar with from his time in Westeros and the name, certainly, wasn't something he was familiar with but upon hearing it, it made sense: the ground shook, the earth quaked. He tucked that back into his mind for further use and shrugged a bit. He hadn't known that the quaking of the ground could potentially affect the water but now that he did, he would be mindful.

"Wouldn't be a good thing, if we suddenly had no water. I don't know about this place. It seems unnatural, somehow, as if the earth's taken a deep breath and is about to plunge into madness. That's not what I normally think about things but this place sort of drives me to it."
