If Cataractae had a bad ending:
The Darkness Mold kills the Hero and the Hero never lives again
Darkness Mold is overgrowing
The world is swallowed in Infinite Darkness
The message of the ending will be:
The world, not protected by the Gem, failed to save the world from the Darkness Mold.
The world is swallowed in Infinite Darkness for a very long time.
