A mysterious entity in Deltarune. Apparently existed in the Dark World long ago and created "Dark Fountains." Silent. His actions have influenced many Darkners like King and Queen. Secret bosses like Jevil and Spamton know of him, suggesting some form of involvement. According to Queen, he is called the Roaring Knight. He creates Dark Fountains by stretching a long hand to the sky and plunging a blade imbued with will like a curse into the ground. However, he cannot expand the Dark World beyond the specific room where the fountain was made (e.g., the unused classroom in Ch. 1, the computer lab in Ch. 2). "The Roaring" A calamity related to the Dark World mentioned by Ralsei at the end of Chapter 2. In summary: Occurs when too many Dark Fountains are created. Everything is enveloped in "Chaos." "Titans" emerging from the fountains will destroy everything. Darkners will succumb to the dark and turn to stone. Lightners will wander in eternal darkness forever. Clearly an ominous event, causing Queen to immediately abandon her plans for world conquest. Since Jevil also constantly mentions "Chaos," it is highly unlikely the Knight is unaware of this fact. It is unknown why this legend exists (and since Ralsei is the source, its truth is questionable), but Ralsei certainly views the Roaring as a threat. This suggests the Knight is the mastermind behind the incidents, but...
