Migration

They were not a huge number of elves living on the plains, at least any more. They had long since been driven into the mountains by the gnomes. Gnomes were always doing that sort of thing; moving into an area, buying up all the land, and driving the locals away with high prices, hipster coffee bars, and the senseless slaughter of innocents. The elves had eventually bounced back, and had formed a commune in the mountains, and were making goat cheese. Which was all fine and good... Until the fucking gnomes decided to get into the goat fudge-making business.
