a tower made of ice, nestled in inexplicably solid clouds high above Crownbreaker territory. at about 10,000 feet above sea level, it's quite cold and staying for more than a few hours is inadvisable, unless you're exceptionally resilient or outright immune to freezing. thrine's home, obviously. the inside of winter's heart is only somewhat more pleasant. very difficult to access for anyone who can't fly or teleport.
