What is Foeslayer's Earring

Arctic enchants an earring to keep Foeslayer warm and safe, and this is a symbol of his early attraction to her and his willingness to ignore the warnings against using his power. The earring is also a symbol of Arctic's protection and of the love between Foeslayer and Arctic, and when Foeslayer takes it off in a moment of anger, she is no longer under his protection, meaning an enchantment cast by Queen Diamond lures Foeslayer out of the Night Kingdom and to her death.
