It was a Portkey!!!
A rustle over a nearby patch of ground sends shivers up your spine. You dart around to discover what made the noise, but are rendered as good as blind in the pitch black night. 'Oh well,' you shrug as you ponder silently to yourself. 'It was nothing.'
...Ah, but it wasn't. (DUN DUN DUN!)
The rustling sounds again, then draws closer... closer... you stand, rooted to the spot with fear. (Yeah, you're a smart one-- something's approaching you in a deserted graveyard at midnight and you just chill and wait to see what it is.) You're able to make out a tall, skeletally thin, cloaked figure, trailed by a smaller one. You consider greeting them-- maybe they can help you find the way back home, you reason-- but even as you ponder, a cold, high voice cracks the night like a whip.
"Kill the spare."
The voice's merciless tone lets you know that it belongs to no one friendly. You turn to run, but before you can, the voice pierces your ears again, sealing your fate.
"Avada Kadavra!"
As green light blinds and engulfs you, illuminating the graveyard, you realize that its too late. The life is sucked from your body, and you'll never get the chance to be rebellious and click a forbidden link again.
