Great Fairy of Ice

The Great Fairy of Ice is a character from The Legend of Zelda: Four Swords. She is a Great Fairy who resides in a chamber within Talus Cave. After Link defeats the Guardian of Talus Cave, a portal opens leading to her chamber.

At the end of each level, the Great Fairy will give Link a key, the kind depending on how many Rupees Link collected during the level and what keys he has already received from that level. The first time Link completes the level with over 1000 Rupees, he is awarded a Silver Key. If Link completes the level again and earns over 3000 Rupees, he gets a Golden Key. Finally, after earning the aforementioned keys and collecting over 5000 Rupees in a level, the Great Fairy will grant Link the Hero's Key.
