In the game Deltarune, creating a Dark Fountain requires a specific and powerful act.
How a Dark Fountain is Made:
The Stab: A Lightner must thrust a bladed weapon, like a sword or a pencil, deep into the ground.
Pure Determination: The act requires an intense surge of willpower of determination from the person making it.
The Result: The room fills with darkness, and the world shifts into a rugged Dark World filled with new rules and monsters.
The Consequences:
More Fountains: Creating too many Dark Fountains causes the Roaring, a cataclysmic event that brings the end of the world.
The Titan Threat: Giant monsters awaken when the sky turns completely dark from the fountains.
Closing Them: The heroes, Kris, Susie, and Ralsei, must seal these fountains to keep the balance safe.
