Faeries allied with the Winter Court are, among others, termed Winter Sidhe, or Winterfae.
Harry describes Winter: "Winter's nature was beautiful violence, stark clarity, the most feral needs, and animal desires and killer instinct pitted against the season of cold and death—the will and desire to fight, to live, even when there was no shelter, no warmth, no respite, no hope, and no help."
It is the Winter Court's job to defend the Outer Gates from Outsiders. and the White Council estimates Mab's troop count to be about fifty thousand. Yet at the Outer Gates, there are more than that in one single formation. The capital of the Winter Court is Mab's fortress, Arctis Tor.
