its a theoretical chart of undertale/deltarune stuff, up and down being meta-existence (up is over existence, like the player or toby fox, being able to directly influence game elements and/or know that they are in a game, down being under existence or deeply interwoven into the games code). left and right are monster and human, or magic and determination. The underground is considered a magical but real place, the overworld is considered a human and real place, the darkworld is considered a magical and fake place, and the forgotten place is considered a "human" but real place.
