The Winter Court is the Domain of the Cold Boy. The Winter Court is a city full of frost-stricken buildings as well as structures formed entirely from ice. In the middle of the Winter Court is a building known as "The Winter's Heart". The Winter's Heart is the true form of the Cold boy, and it is said all Children of The Cold have seen this form once and it has made their eyes turn black.
The Winer Heart is, supposedly, a large building that resembles a palace, and is usually where the Children of The Cold reside if not doing business for the Cold Boy.
