Their purpose is to mantain Nemesis' curse on the land so that he can take care of other things. They must be found and destroyed by the player's character in order to decurse the land and progress through the game story.
There are three guardian stones on Land 4, each related to a part of the curse and a specific quest:
- Stone 1 - Makes fireballs rain from the sky. Under a spiritual shield near the Japanese village (See The Totem Puzzle).
- Stone 2 - Causes heavy rain and lightning bolts to strike everywhere. Guarded by Sleg (See The Defending Ogres).
- Stone 3 - Makes the sky permanently red like blood. Entrusted to a lonely man who is forced to worship Nemesis so that no harm may come to his wife (See The Heartbroken Man).
