After the death of Xande the Cloud of Darkness enters the World of Darkness to complete her plans of destroying both worlds with the powers of the Void. When the Warriors of Light come to stop it Cloud of Darkness is too powerful for them to defeat. The Warriors of Light search for the Warriors of Darkness to weaken it and find the Dark Crystal. The Cloud of Darkness orders its guardians to guard the Dark Crystals and kill the warriors. Each guardian appears when the Warriors of Light touches their Crystal:
Each time one is defeated by the Warriors of light, one of the Warriors of Darkness appears to help the Warriors of Light by giving them important information and weaken the Cloud of Darkness. Eventually all of the guardians and the Cloud of Darkness are defeated by the combined power of both warriors of light and dark.
The Guardians of the Dark Crystals appear in the Dawn of Souls version of the original Final Fantasy, and every version of the game released thereafter. They reside in the Earthgift Shrine bonus dungeon available after the Warriors of Light defeat Lich.
The Guardians appear as bosses on the 12th floor of the Depths.
