This, basically. If we assume most of the Dark Fountains were created by Dess, then Dark Worlds and Darkners are based off of the Kris, Asriel, Noelle and Dess imaginary adventures. Then the FUN gang adventuresbare akin to someone's childhood imaginary stories come to life.
FRIEND seems to be a part-hand thing that can reach into Darkners and control them like puppets. Like playing dolls except the dolls have sentience and lose their free will when they're being controlled.
Schizotheory time: I feel like "the prophecy" might be a full reenactment of their past pretend-adventures, up to the point where Dess disappeared. Kris and Ralsei seem to be aware that their job is trying to act out this adventure perfectly to placate Dess's spirit or something. It might be something many of the adults in Hometown are aware of, which is why "the prophecy" is part of their religion. I'm betting Carol and Toriel are major players in this and are withholding information from the kids.

WAITER, WAITER, MORE VOCALOID CROSSOVERS PLEASE!
