The Endless Winter is a time in the future prophesied by the Fae that will herald the death of all Wonder, Creativity, Magic, and Dreaming in the world. It will be a time of Undoing of all the Faerie people and perhaps the end of the world.
Winter is closer at hand than even the most pessimistic of doomsayers predict. Some sidhe are aware of this fact and realize that the fae, in general, are not ready to face this time of tribulation. Perhaps one of the greatest current weaknesses of the sidhe is the growing schism between them and the trolls. Both the sluagh and the Beltaine Blade are encouraging this growing enmity, for their own disparate reasons.
