Jade Fern Grove was destroyed by global warming

A chase! Nunataq's features lit up, when she understood, what kind of game the lady was offering, and did not have to be told twice. She ran after her, catching up fairly quickly attempted to nip at the older wolf's heels and then sped past her, because it is rather difficult to come to a sudden halt, when you are driving 130 km/h (well, wolf speed equivalent of this). Instead she made a large loop, zig-zagging among trees and came leaping back at her playmate to see, how far she had got.
