|Icecrown of Irrisen|
Source: The Witch Queen's Revenge, pg(s). 62
The Icecrown of Irrisen is a jagged crown composed of ice that never melts, crafted by Baba Yaga as the symbol of office of the queen of Irrisen. It has since been worn by all of her daughters who sat on Irrisen's throne. While queen, the daughters stop ageing and can shape the Royal Palace in Whitethrone at will. Once worn, the Icecrown of Irrisen can only be removed by Baba Yaga, when the wearer dies, or when the unnatural winter of Irrisen ends, causing the Icecrown to melt away on the first day of spring.
