Grimm, once known as The Nightmare, was one of the two children of The Dream Lord, born soon before their father perished in a fight against The Shade Lord. As his final wish, they both inherited an equal chunk of his realm and were meant to rule it together. Grimm's sister, The Radiance was tasked with watching over the mortals’ dreams and be their guiding light in hopeless situations. The Nightmare’s role was to guard the mortals’ nightmares and help them overcome their fears.

Grimm was always the more rebellious of the two siblings. He would frequently pull pranks on his sister, and it was clear that he wasn't as interested in the godly matters as she was. But more than anything, he was naive. As he grew up, he believed he could leave Godhome to mingle with the mortals with no consequences, and he ignored the growing tension between him and The Radiance. As time went on, the two siblings grew more and more distant. The Radiance was dedicated to fulfilling her father’s wishes and preserving his legacy, while The Nightmare spent most of his time away from Godhome. While he did his duties and watched over their nightmares, he held no attachment to his father’s legacy, which infuriated The Radiance. She saw him as unworthy of the power given to them, and he responded to it with annoyance. He would continue with his mortal plane activities, seeing it as his playground.

The Radiance, on the other hand, was obsessed with living up to her father's legacy. She saw the old ways of the gods as the correct one, and thus she never created a physical form for herself. Her obsession eventually turned into paranoia, and she saw every disagreement with her brother as a sign that he may be conspiring against her.

Their disagreement culminated after The Radiance created the Moth Tribe - a tribe of bugs who would serve as her main way of reaching the mortals, capable of entering the Dream Realm with the use of a dream nail. To get back at his sister, Grimm decided to disturb the tribe, often interrupting their rituals and even inciting them to rebel against her and her stuck up ways. In his eyes, this was nothing more than a mere prank, he could not care less whether they would remain loyal to her. Unfortunately, as a result, some of them started doubting their creator, which infuriated The Radiance. She found out about her brother's scheming, and after he returned to Godhome, she attacked him without giving him a chance to explain himself, seeing his actions as a direct threat to her authority, and even as an attempt at obtaining complete power over their realm. Ultimately, Grimm lost the battle, caught off-guard by her sudden aggression, and was subsequently banished from Godhome and trapped him in his Nightmare Realm, now separated from Godhome.

Years passed, and The Radiance's influence over the mortals of Hallownest weakened. As it turned out, they were more drawn to beings they could actually see and touch, and by the time she realized her mistake, they all turned from her in favor of the two new rulers of Hallownest, The Pale King and The White Lady. Blinded by her rage and the fear of being forgotten, she retaliated with the terrible infection: a deadly mutation of the dream essence, which took over the minds of those affected and made them susceptible to her voice. Her rampage was temporarily halted by The Pale King, whose Pure Vessel absorbed the infection. Unfortunately, this solution did not last, and she eventually broke down the vessel to the point where they could not contain the infection anymore. Years later, she was defeated by another of Vyrm's offsprings, Ghost of Hallownest, who united the void to form The Shade Lord, ascended Godhome and overpowered her, ending the infection for good.
