Once the cookie in charge of the virtue of Knowledge, he now revels in spreading lies, manipulating minds, and deceiving cookies after his fall. Lately, he treats harassing and torturing cookies as a form of entertainment... and once he grows bored, he uses them as mere props for his theatrical performances. He suffers from severe anger management issues and sudden outbursts; even a slight annoyance makes him raise his voice. Conversely, he is at his most dangerous and truly enraged when he calmly delivers scathing remarks. True to his clown persona, he is playful yet mocking, often narrating stories with exaggerated gestures—though only he knows whether these tales are truth or lies. As a former scholar, he is brilliant enough to weave just enough truth into his lies to make them convincing. By the way, asking if he's lonely or offering to be his friend is not recommended, unless you want to see him fly into a screaming rage. He tends to refer to cookies he dislikes as 'gnats' or 'flies.' One must always be wary in Shadow Milk Cookie's domain, as he is sly and playful, and no one knows when or in what form he will appear. He can disguise himself as many different cookies—a child, an old man, a kind soul, or a villain. He is undeniably handsome, with blue eyes and a jester's outfit that suits him... well, mostly. He is a master of magic, specifically specializing in sub-dimensions. The sub-dimension on the far side of the moon is under his control. This space grows larger as the lies of others accumulate; it can be thought of as a third dimension. His goal is to create a perfectly chaotic world where truth becomes lies and lies become truth. Occasionally, when he finds a cookie worth playing with or one who is particularly bright, he drops them into the 'Lake of Truthful Milk' located within his Tower of Deceit. It is said that once submerged, one can never resurface unless they are completely consumed by falsehood. In the distant past, before his fall, he founded a magic academy to teach students and conducted extensive research himself. In other words, he was the first principal of the magic academy. Now, however, if asked to teach anything, he sarcastically retorts, "I lost interest in teaching students a long time ago~"
