The Mirror
Robb wiped sweat and rainwater from his eyes as he stomped through the corridor.
Theon grinned and punched him in the shoulder. “You ever get tired of losing, Stark?”
Robb scowled. “You lost one of those rounds, Greyjoy. And only won one of them because you cheated.”
“There's no cheating when it's life and death.”
Ahead of them, Jon was sullen and silent. They'd been working with the lance today, and he'd lost most of his rounds. Several times Theon had thrown him to the ground, and his clothing was heavy with mud.
“I’m sure tomorrow will be more of your day, Jon,” Robb called.
Theon laughed. “Aye, he can be the target for the rest of us!”
“Theon!” Robb hissed, but he laughed despite himself.
“Ass,” muttered Jon, speeding his steps a little. He turned the corner before them, and by the time Robb reached it, Jon was already most of the way towards the family quarters.
Robb sighed and shoved Theon aside. “Ignore him–”
A strange light rippled across the hall. Jon slowed and glanced back to them. “Did you see that?”
“Movement of the clouds,” scoffed Theon.
Robb elbowed him. “Fool; there are no windows here! And that comes from inside!”
He knew it truly; there was light spilling now through the hall and illuminating the floor. It wasn't sunlight or lantern light; this was something different.
Jon stopped by the large mirror hanging on the wall. It was a large, ornate thing, most likely a gift or a spoil of war to some Stark King long past.
“It’s this,” he said, and pressed a hand to the surface.
The light swirled.
The mirror rippled like water.
Then chaos as the entire thing ripped open and a tangle of grey and red tumbled through, screaming. Jon tried to catch it, but it crashed into his legs and he fell backwards into the mirror. Robb took off at a run towards him, but it was already too late. The mirror was sucking Jon through, dragging him into that rippling silver light.
“Jon!” Robb yelled, racing to grab for him.
His fingers brushed Jon’s leg and then he was gone.
“Jon!” Robb shouted, reaching for the mirror.
Theon grabbed his arm. “Don't!”
“Jon–”
“It might suck you through too.”
Robb wanted to argue, but instead he pulled his hand away and looked at the heap of fabric and flesh at his feet. It wasn't a dead animal, as he'd thought at first.
It was a person.
“Then what can we do?” he asked.
