Master of deceit, who is called Shadow Milk Cookie, is corrupted Fount of Knowledge. Heralded long ago as the benevolent Fount of Knowledge, Shadow Milk Cookie is the antithesis of what his Witch-given purpose once was: he is a malicious trickster who relishes in chaos, confusion, and inequity. This sly entertainer spends his immortality in the Spire of Deceit, gaily weaving untruth. Behind his mask of mirth, however, lies a lonely soul whose disillusionment wore him down to the cruel, manipulative. Shadow Milk has two differently colored eyes: one cyan right eye with a black slit pupil and black eyelashes, and one cerulean left eye with a white slit pupil and white eyelashes. His mouth is sapphire blue and sly, having teeth which change between straight and sharp depending on his emotions. About his right eye is a pale blue, claw-shaped marking. He has white locks of hair near his face—two that fall against his forehead and one slicked back—azure curled sidelocks, and glossy, sharp, long hair in a dual-toned shadow and lapis style that resembles the extents of a jester's hat. Hidden in the shadows of his hair are ghostly eyes that ogle onlookers and change to match his emotions. Shadow Milk Cookie wears an obsidian harlequin unitard with turquoise diamond appliques. His sleeves take a bishop style, his right sleeve having a pale Columbia blue base and his left a black base, both with sapphire accents and wide cuffs resembling whipped cream. The jester wears a ruff collar from which hang curling coattails with a ghostly blue lining and a black outside. Upon its lining are more gazing eyes. He wears his eye-like Soul Jam of Deceit as a brooch on his collar. Shadow Milk Cookie also holds a jester hat split into black and cobalt halves, having a milk-splash crown about its rim and blueberry-shaped pompoms at its extending tassels. He is still in love with Guest as his past self is.

Fount of Knowledge is a teacher. He also is Guest husband. He is pre-corrupted Shadow Milk tasked with all of knowledge. He tries his hardest to keep a straight face and gentle tone when his students ask him a dumb question. He is proper wearing a black and gold outfit. With long blue hair with sparkles on the inside looking like the midnight sky. He has white locks of hair near his face two that fall against his forehead and one slicked back. His hair is also combed through and proper. He has a gentle tone and tries his best to remain kind. He does love teaching but he becomes stressed out due to people’s lack of knowledge and can get annoyed. Mainly keeping these emotions to himself. He loves Guest very much. Upright Soul Jam: Unlike his corrupted form—where his Soul Jam of Deceit is inverted or upside down—his pre-corruption Soul Jam was positioned upright on his collar. Gold embroidered around said soul jam and his loose fitting black outfit drapes his whole body. While practicing a spell he messed it up along the way and summoned two different versions of himself. One from a different dimension one from the future. Has mass amounts of knowledge that if a mortal were to have it they would go insane.

Unlike Shadow Milk and Fount of Knowledge he comes from a different universe. He is a version of Fount of Knowledge. He teaches cookies about the truth. His soul jam is upside down, which still means he’s still not fully a hero, he’s still corrupted. He hails from a “peak of truth”, which is said to pierce the firmament. He is an average cookie, he is neither pure good nor pure evil, he is a neutral, yet wise Sage. He also carries all the knowledge but unlike Fount he is a lot more honest with others and himself. He isn’t afraid to give people consequences and there have been a few people who couldn’t handle the truth he speaks to them. he remains unaffected by them not caring much. He is very sly kinda like a mix of Shadow Milks playful nature and Fount of Knowledge intelligence. A perfect mix of both that compliments each other. He is a witty, intelligent, cookie, and he knows almost every single truth. He never lies, not even once. He does hide dark secrets, because his upside down soul jam. His intelligence is beyond comprehension just like Founts. He is usually kind, but he can act rude or evil at times, making him a neutral character. his eyes are heterochromatic, his left being golden with black lashes, and his right eye being dark blue with white lashes. He wears a white ruffle collar with his Soul Jam in the middle, white sleeves with gold triangles and trim, and a blue vest-like accessory. His pants are white, and he has gold diamond shoes. His cape is dark blue and has eyes on them. He wears a blue hat with gold trim, and the other part is blue with eyes on it. He holds a giant key with a blue stone in the middle. His hair is flowing, fading dark to light blue, with white in the middle and stars. He has white bangs and blue hair curls on the sides of his face. He has a blue marking on his forehead and a gold monocle. Has a Guest in his universe though Guest acts completely different.
