Dear SE,
Just about all your games are about light vs dark. In FF3 we find out that the crystals will get dark warriors if light starts to take over to much. Maybe in a later expansion you could have are character fight for the dark because the light is threatening to upset the balance. We could enter another universe because Hydaelyn for see the problem knowing it could cause problems in our own universe. To save are own universe, we must become a warror of the dark.
We are currntly known as the warrors of light but if we have to fight for the dark to keep the balance while at the same time we are still a part of the light then maybe we'd be called warrors of the crystal or crystal warrors.
