It's barely more than an idea that has been budding in my head for a few nights, but here goes. An Artemis Fowl and Underland Chronicles Crossover.
Prologue
"Butler, the entrance should be around here."
The words shot through Gregor's spine like ice. Who were these people to be walking around their apartment building at this time in the morning? It was three am by the glow watch Mrs. Cormaci had given him. He'd gone to take a walk around their building because he couldn't sleep, as he was all messed up on the sleeping system from being underground for months, but he also wanted to check for a scroll in the laundry room grate. He halted, though, when he heard this unlikely pair with his echolocation.
The first man, Butler, as the other kept calling him, was a muscular eurasian man, easily two hunderd pounds and nearly seven feet tall. He kept glancing around uneasily as the much smaller figure next to him looked around.
The other one was a boy around Gregor's age. He was skinny and wore an expensive looking suit, and appeared to be in charge.
"And this is different from the fairy underground, sir?" the huge man asked.
"Yes, Butler, this is completely different." The boy paused before speaking again. "Is this a scroll?" There was a echoing thump as something hit the side of the dryer, as the scroll was pried loose from the grate. The man called Butler began to read aloud.
"Gregor,
I know you're still in New York, and not in Virginia. I have my sources, as do we all. I suggest you come back down here, but I'm not going to tell you why.
p.s. Do you have any idea how long this took me to write without thumbs? "
Ripred must've wrote that, Gregor figured. The chilling voice of the adolescent spoke up again.
"Very unusual. This must be the way down. Butler, do you think you could move the dryer out of the way of that grate?"
There was a groan of metal as the beast of a man moved the dryer out of the way as if it were nothing. Gregor had a sinking feeling in the pit of his stomach as the rattling that signified the grate had been opened began to echo in the halls. The strangers were in the Underland!
