Authors Note: Because the idea was funny the first time I read it on the 4chan wiki, but is getting rather dull. One thing that always bugged me was that none of the factions would try to kill the human.
Robert's first thought was that someone was humming. Then he saw the glow. A sickly, bright green light was creeping under the bottom of his bedroom door, accompanied by the constant, low-pitched whine that had caught his attention. There was a crackle, and a gust of hot air billowed against his shoes.
Standing against the doorway of his bedroom, Robert narrowed his eyes suspiciously.
"Shawn, is that you in there?"
There was no response. The humming continued.
"Shawn, what are you doing? You're gonna be in trouble when mum gets back."
There was still no reply.
"Shawn?"
Silence.
"I'm coming in, ok?"
Robert opened the door, and instantly gagged. The room was filled with a peculiar smell, like a combination of ozone and roast beef.
"Ughh..." he coughed as he walked inside, sleeve over his mouth. There were clouds of smoke drifting through the air. "What were you doing in there?"
The room looked like an army had been through it. The bed was a smoldering mess, and the desk was a pile of charred pieces. There was a massive crater in the wall, which looked as though it had been eaten away by acid. The lamp was lying upended on the floor, casting long shadows across the room. No sign of his older brother though.
"Jesus." Robert said, then blinked as he saw a cluster of pyramids float up from the floor. The smell was much stronger now.
"That's weird." was all he could say. The strange pyramids looked just like the toys his older brother collected. He'd called them Monoliths and Neocrons or something, then started babbling about armour saves and special rules. Now the pyramids were floating in mid-air and appeared to be glowing from within. They didn't even look like plastic anymore, their sides caked with ancient dust and flaking runes. Just looking at them made his eyes hurt.
"What the..." he started, then trailed off as he got a closer look at the floor. There were dozens, no hundreds of tiny metal figures standing in formation on the floor. Every one of the skeletonal figures was holding a long, glowing device. And they were all moving directly towards him in perfect formation.
As eerie as that was, it wasn't what had made him stop. What had was the charred, almost unrecognizable mass curled up behind them, bone showing through its agony-induced grin and the tatters of its clothing. He could still make out the jacket it had been wearing.
"Shawn?" he whispered, oblivious to the shapes emerging from the gloom. Tiny, ancient shapes.
There was a buzz, and arcs of lightning sparked from the nearest pyramids. Robert instinctively raised his hands, which was what saved his life. His hands went numb, and he suddenly couldn't feel his fingers. His face was sticky, and stung painfully.
Pulling his hands away, he stared at them. His fingers and part of his hand were completely gone, the wounds cauterized. There was no pain, only a lack of sensation from the missing digits. Numb from shock, he felt frozen in place.
The pyramids's crystals glowed again, and Robert screamed in terror. His paralysis gone, he turned and started to run.
He felt something hit his knees, and fell heavily, his head slamming against the floorboards.
Behind him, the silent army marched in perfect formation.
