The Boy Under the Stairs gets a scary friend. (crossover)

don't expect much more from this, but enjoy!

Harry was sleeping in the Cupboard under the stairs when the voice spoke.

"Harry. Harry Potter."

"Who...who are you?"

"A friend. I was... in the neighborhood so to speak, and I saw you."

"But nobody can see in here. Uncle Vernon gets angry. I'm the fre--"

The entire house shook. "No. That is not a word you will ever use for yourself, not a word you will ever be forced to answer to again."

"Vernon will--"

"I'm having a chat with Vernon."

Vernon and Petunia were sitting in their dining room, petrified. There were insects covering the floor, the walls, everywhere. Strange figures seemed to form out of the air, then vanish. And that voice. That chummy, terrifying voice. And the roast that Petunia had been preparing--reduced to just the bones in a second.

"It is terrible to mistreat those who are bound to us by ties of blood, is it not?" The voice continued. "Now Petunia, you said… you were protected. I'm very interested in that, so why don't you tell me everything?"

"How… Dumbledore said you—"

"There are higher powers than mankind. Sometimes, They take a hand. It may be, I am their representative, sent here to you. A chance, as it were. But I am quite interested in this… Dumbledore and why he would place a child with you…"

"Are you an angel?" Harry asked.

"Hardly." The voice paused. "But maybe, a friend, if you will let me be one."

"Could you keep Dudley from playing 'harry hunting'?"

"I shall, but Dudley…" The voice paused. "Dudley is also a victim."

Harry blinked. "But Vernon and Petunia love him!"

"Have they ever told him 'no'? Being a parent isn't just about giving your child everything he wants. But no, you will not have to worry about "harry hunting" in the future."

Downstairs, Petunia finished telling everything.

"Fascinating." The voice said. "But I have a suggestion. After all, it is important to care for our children, is it not?" Petunia and Vernon gulped, glancing up to where Dudley was sleeping in his room. "Fear Not," that voice continued. "Children need not fear me, though Dudley… yes, Dudley is in need of some assistance. So, I have an associate, who was brought here after a battle with a False Angel. She shall serve as your nanny for both Harry and Dudley. I shall place my hand over this fine house and grant it my protection. If the… "freaks" as you called them once—never again, in my presence—should attempt to harm your children, I shall protect them and very spirits of the dead shall rise up." One of the wraiths, half seen in the kitchen, seemed to turn to look at them, and Petunia shrank back. "After all, there are so very many spirits upon this storied isle. Do we have an accord?"

"Yes!" the both burst out.

"Excellent. Vernon, she won't have any ID at first, but fear not, I am going to rectify that issue within a week. I foresee an excellent partnership in the offing. Do not delay on giving Harry his own room. The nanny will be suited to the small guest room."

And then the bugs and wraiths started pouring out of the house, leaving their room like it had been, except for the glance Petunia had of the kitchen table, visible through the door… and the picked clean bones on it.

The next day, when Harry got back from school, there was a thin girl sitting in the living room with a nervous Petunia and Vernon.

"Hello," she said. "I'm Taylor Hebert, your new nanny."

Harry was thin. We'd have to fix that, and Dudley was looking to have his first heart attack sometime during his senior year of school. We'd have to fix that, as well. A bully, someone who had never had no said to him. Well, honestly I'd seen much worse, although Harry hadn't, and if he was a Bully, he didn't have the strength of Leviathan, the sadism of Victor, and the Killer instinct of Hookwolf… So I expected I could deal. But right now it was time to get started. Was Harry a pre-Trigger parahuman? Various organizations on Earth Bet had attempted to induce triggers. Was this the same?

I didn't know. I did know that it was unlikely that the Simurgh had knocked me through that portal by accident. Especially since I'd come out close enough to the house to see Harry's 'room' via my bugs. I'd stifled my first impulse since he didn't look to be in immediate danger and had listened to them over the course of a few days. Fortunately. But I was here for a reason, her reason. Which meant that something here was going to, or already had, bite me on the ass. Well. It wouldn't be the first time I had to hit the ground running…
