Imprisoned

Jessica woke to an ache in her back. The ground beneath her was carpeted in leaves. She became vaguely aware that she was in a sitting position, propped against a tree. A thick chain bound her to its rough trunk. She looked around, and realized that there was a figure slumped beside her.
"L-Luna?" she said, her voice hoarse.
The figure woke with a jolt.
"Jessica!" she cried, surprise evident in her voice, "Wha- Where are we?"
"I haven't the slightest idea," Jessica admitted, "Only that we are chained to a tree in the middle of the woods."
"Oh, lovely," Luna groaned.
“And joy of joys,” Jessica commented, “These chains are bound.”
“Yes, dears, yes they are,” came a voice from behind them.
Jessica stiffened.
“Who is it,” Luna snapped, her voice betraying none of her fear.
“The man you thought was dead, but the man you know none of. The man you thought was a victim, but was instead an accomplice. I’m Rufus Pemberton.”
Jessica almost laughed, he sounded so ridiculous. He stepped out from behind them, so they saw him in full. Jessica was unused to looking up at people, and she figured this was how short people saw her.
The man in front of them was dressed in a khaki trench coat, that fell just above brown Herman Survivors.
“Where are we?” Luna said, her voice taut.
“You? You’re under our... Custody.”
The way he said it made it seem like an understatement.
“So we’re your prisoners?” Jessica snapped.
“Yes,” he said, “Prisoners. Prisoners to be ransomed when the rest of your Sanctuary friends get here.”
Suddenly, his hand went to his pocket.
“And they’re going to have a big surprise when they do!”
He pulled his hand out of his pocket, and Jessica and Luna gasped. In one deerskin-gloved hand, Rufus Pemberton clutched a black sphere. Then, he placed one hand on the top, and one on the bottom, and opened it. Luna screamed as a sliver of darkness leapt from the opened sphere. It darted toward her.
“No!” Jessica cried, “Luna! NO!”
Luna sealed her lips, and struggled against the chains, but it was too late. The Remnant pried open her mouth, and slid down her throat. Spasms racked her body. Jessica screamed over and over, but slowly, viens of blackness covered her face, ringing her lips. Her eyes became flat black pebbled, her lips darkening to ebony. Her face contorted into a savage smile. Tentatively, Pemberton stepped forward. He unwound the chain from Luna, and she stood up.
“Hide yourself in her form, and guard the other one. When the rest come, bring them to me.”
Luna nodded, and the blackness vanished from her face.
Pemberton turned, and walked away, leaving Jessica with the Remnant.
