During the events of Team SHDW Volume 1

Hallow Eve was twenty years old when he came across an abandoned house. He had been kicked out of Beacon several months prior for being... well, let's just say misbehaving was putting it very mildly. He was seen by most as a total creep, and his sanity was often called into question. After snapping at a teacher and attacking them, he was expelled and left to wander, having no family left to go to.

Hallow had yellow eyes, as well as a strange mixture of orange and black hair. His weapon was simply a kitchen knife that could grow into a machete, the simplistically of it being something he was mocked for. His Semblance was what made him creepy to everybody. Simply named Dark Void, the area around him is surrounded by darkness, and whoever was unfortunate enough to get trapped in it lose all senses except for hearing.

During this, the only thing the victims ever heard was the sound of giggling.

After wandering for four years, Hallow found himself on the island of Patch, in front of a run down home surrounded by police tape lines. He didn't know the whole story, but he knew that about a year prior, the White Fang destroyed the home and killed two people who lived there.

Hallow smiled, quite excited about staying the night in the dead people's house. He made his way under the police tape and through the giant hole in the wall. Deciding to explore the house a little, he made his way down to the basement of the house. He certainly didn't expect what he found. In the basement was a large laboratory, filled with vials filled with liquids, as well as a few needles for shots.

But there was suddenly a low growl behind him. Hallow slowly turned to see a pair of red eyes staring right at him. A Beowolf. Hallow's mouth twisted into a wide grin, bringing out his knife, but the Grimm had already pounced, knocking into the man, sending them both sprawling, knocking over a few shelves. The two wrestled for a few seconds before Hallow stabbed the Beowolf in the gut, causing it to howl in pain, but not enough to kill it.

It clawed at his face and eventually hit him into a shelf. Hallow looked up and there was a sign that read "Prototype Enhancements". But he didn't necessarily care. He grabbed one of the vials in one of the shelves and downed it in one gulp.

But to his utter disappointment, nothing happened. Hallow growled in anger and proceeded with killing the Beowolf. Despaired at nothing happening, he walked back upstairs and crashed on a bed.

And then the nightmares began.

All it was was a faceless voice speaking with him. It was a creepy, high pitched voice speaking to him, and the days after Hallow woke up, those words echoed in his mind, becoming his own ambitions. But the descent into this situation was gradual.

At first, the words spoken by the voice were quiet advice, whispers. After hearing those whispers, Hallow's life changed from wandering man to wandering thief. Steal for survival, the voice had advised quietly. When the voice began talking loud and clear, Hallow's thievery became less and less subtle. It wasn't long after that advice that Hallow became a wanted man.

Then the advice became commands... all of which Hallow followed, his resolve quickly dissipating. "Wanted for Thievery" became "Wanted for Murder". It wasn't long after the commands started coming that Hallow's agreements became instincts. Whatever the voice said went. It was absolute. And then... there were no more thoughts. He murdered humans out of no purpose... somehow sensing their fear and despair, and following that. Hallow wandered Remnant, killing any human he came across.

And now that his mind had changed, his body was next. His teeth grew sharper, his eyes became slitted, his feet and hands sprouting claws, he grew a long tail, wings sprouted from his back, and his skin turned pitch black. But his face... out of nowhere, a mask resembling that of a Grimm's face appeared on his own. He had become more Grimm than man, and he no longer spoke in any human language, only growls and roars. The only thing human about him was his laugh, which even then was very inhuman.

His, no, its reputation spread throughout Remnant like wildfire. Entire villages and bandit tribes alike were laid to waste, some witnesses even reported seeing him at the Fall of Beacon. Newspapers labeled him as "the worst monster since the Ogre", only frightening more people. This "Demon Grimm" and it's rampage went throughout the world, seemingly taking pride in the fear it caused.

But one day, in Vacuo, it's own kind turned against him. Grimm Hallow was taken completely off guard when packs of Beowolves and Ursai charged him. Though taken aback, the Demon did what it did best: killed. From Ursai to Lancers to even Death Stalkers, nothing got past it. And when it seemed as though no more were left... there were loud, thunderous footsteps.

When the Demon looked up, it suddenly understood why the Grimm had targeted him: they were ordered to by the very thing in front of him. The pale white skin and the large spear were unmistakable. The Ogre of Grimm itself had come to fight the Demon. Though for the Demon, this just raised the question of why the Ogre was attacking him in the first place, but it didn't ponder that question for too long, because the battle began.

Blow for blow, strike for strike, the two were evenly matched. Hallow was faster and its smaller size made it harder to hit, but it also had a relatively weak weapon compared to the Ogre's, who also had the bulk to tank more hits. The two battled for what felt like days, the Demon's laughter dying down over time, slowly losing stamina. The Ogre finally got enough hits in, and Hallow blacked out.

It woke up after it was tossed onto solid ground. The Demon snapped to attention, turning towards who threw him, and saw the Ogre. Then it looked around and saw himself in a strange new environment. The place was colored purple and black, with the terrain being very rocky. Then he saw what he was thrown at the feet of.

It was a woman, who wore a long, black dress, had braided white hair, and skin just as white as that hair, black veins visible on her arms and face. Her red eyes that seemed to stare into its soul felt so captivating to the Demon. She was terrifying... something it found amazing.

"Hello, Hallow," she said in a melodious, yet ominous voice, "My name is Salem. I would like to have a talk with you."
