Earth Guardians are land-bound Guardians who serve Hylia and protect Silent Realms from intruders in order to test Link's Courage, Wisdom, and Power. Earth Guardians are tall, lanky enemies that wield giant maces. Earth Guardians remain dormant in their Silent Realms until intruders trespass outside of the protective circles of Trial Gates. When awoken, Earth Guardians will immediately give chase toward Link, regardless of his position and whether he is in sight or range of them. However, because they exclusively walk along the ground, they cannot maneuver around certain objects, allowing Link to escape their advance.
Earth Guardians can be rendered dormant by collecting Sacred Tears, which also warps them back to their resting location for a period of 90 seconds. Even when Earth Guardians are rendered dormant, they can be awoken by various factors, such as Link treading through Waking Water or by Link being caught by a Watcher. If an Earth Guardian manages to catch Link, it will strike him with its mace, shattering his spirit and causing him to fail his trial.
