Fortunately for both the Peerage and the people living in the demonic territory, they found the killer on the seventh night of searching. But what they found in a dark alley was not what they were expecting, at all.
Instead of finding an adult psychopath, they found a small girl that wasn't just unhealthy skinny, but looked like she was about eight years old, maybe older but looking younger than she was due to how skinny she was. And the rags she was wearing certainly didn't help the matter. She had a very pale complexion and snow white hair, but that wasn't what stood out about her the most. No. What stood out about her the most was the four blood red tentacle-like appendages protruding from her lower back, each of them being roughly two meters in length and each of them tipped with a crimson barbed tip similar to the head of a spear. The second thing that the Peerage took note of was the girl's eyes, pitch black sclera with crimson irises. The fact that the girl was currently eating what appeared to be a human liver did not however escape notice despite her shocking and rather haunting appearance.
Despite the quite disturbing and intimidating image of the scene, the girl's expression and posture told a very different story. She was not only scared, but also very lonely and (obviously) very hungry. Lilith, being somewhat reluctantly familiar with this kind of behavior, made a gesture that told the other members of her Peerage to stay put, before she slowly started to approach the frightened girl as calmly and carefully as possible. Once she was about two and a half meters away from the girl, close enough to talk to the girl but still out of the barbed tentacles range, she knead down and started speaking with the girl.
"Hello little one." Greeted Lilith in a tone as calming as she could, which didn't actually do much to calm the girl down, probably because of her mask and rather intimidating visage.
"Who are you?" Asked the girl carefully, her voice sounding not only absolutely terrified but also submissive, swallowing the last bit of the liver she had been eating as finished her sentence.
"Me? Well, my name is Lilith Potter and I'm the owner of this territory. May I have the pleasure to know your name?" As Lilith said that she sat down cross legged and removed her mask and hood, revealing her face to the young girl.
"I'm not sure if I have one, but the scary man tend to call me Jack." Replied the girl, now known as Jack, timidly.
"Nice to meet you Jack. I just wish that it could have been under better circumstances. Now… if you don't mind me asking, but what are you exactly?"
"I'm not sure what I am, but the scary man says that I'm a ghoul. Or at least part-ghoul." The reveal of Jack's species was something that made the entire Peerage eyes widen in shock, not that Jack seemed to notice. Apparently perfect night vision isn't an ability ghouls possesses, or at least not a natural one.
"Hmm. Can you clarify something for me Jack?"
"Sure."
"I've read a bit about ghouls and their behavior. Tell me, is the only thing you can eat that doesn't taste disgusting human flesh?"
"No. I can eat pretty much anything, but human tastes the best." Clarified Jack, who had apparently calmed down enough to not only retract her tentacles into her lower back but also start approaching Lilith, albeit in a very timid and rather animalistic way, as she was walking on all fours, kind of like a monkey (in terms of how she moved).
"Right. I've noticed you mentioned this scary man a few times. Is he your dad, you don't have to tell me if you don't want to."
"I don't know. Can't remember if I even had a dad, or a mom for that matter." At this point Jack was practically sitting on Lilith's lap, subconsciously snuggling up to the older girl, who proceeded to wrap her cloak around the little ghoul like a blanket. "Hmm. You're warm."
Lilith had to suppress the urge to squeal with delight as the little ghoul fell asleep in her arms, wrapped in the Devil/Reaper-hybrid's cloak like a baby in a blanket. For a few minutes, nobody did anything, except for Lilith, who came to a decision.
"Hey Jack." Exclaimed the king of the British Peerage gently, waking the little ghoul sleeping in her arms up.
"Yeah?" Replied the ghoul groggily.
"Would you like to be a part of my household, my Peerage, my little family?"
"Yes!" Exclaimed Jack excitedly without the slightest hint of hesitation, earning an amused chuckle for Lilith.
"Are you sure? You'll be trading your humanity and become part-Devil if you agree."
"I don't care! I don't want to go back! I want to stay with you!" Exclaimed Jack with tears and resolve in her eyes, which was now a yellowish green with a normal colored sclera, hugging the older girl tightly.
"Very well then. Jack. Lie down on the ground and let us proceed."
When the Peerage finally returned to Hogwarts, which was roughly around midnight, it was with a new member of their Peerage and family. Jack the Devil/Ghoul-hybrid, Lilith's first Pawn who consumed a total of four pieces. Lilith, Hermione and Luna found themselves having a fourth member in Lilith's bed that night. Jack.
