Prologue

...

Place: Unknown

Date: 28th February 550 AR

Time: 6:54 AM

"Anna." She murmured.

Her little sister twisted to face her, draped in black with her hair twisted into a bun at the top of her head. She found herself unsurprised at the blankness in Anna's eyes and surprised at how she had already gotten used to it.

Conceal. Don't feel. Don't let them know.

Her palms slipped over Anna's clothes smoothing the creases. "Have you finished preparations ?"

"Yes, Snow Queen." Her hands twitched at her title but continued straightening out the collar.

"And your target ?"

"Sighted and confirmed." Anna replied, spine ramrod straight and eyes ahead. She made no movements when her sister pulled out one of her knives from a sheath at her lower back and inspected it in the light.

"These daggers are getting old. Remind me to purchase you a new set once you return from this mission."

"As you command, Enforcer."

Elsa slipped the blade back into its place and placed her hands on Anna's shoulders. Once upon a time she worried about hurting her sister with her touch but those fears had faded away with Anna's innocence and the lives of their first kills.

Anna didn't have a heart to freeze.

"It was a request, Anna." She stepped back letting her hand fall back to her sides.

"Be cautious. Your target is no ordinary civilian. I expect your return in a fortnight."

Her sister nodded at her and took a step back before spinning on the balls of her feet and entering the airship docked the hangar. In a matter of minutes, the ship had powered up and away leaving her with only the scent of ashes and chocolate.

"Has Enforcer Fifteen left already ?"

She whirled around to fix her sight on the Anguis and kept the ice trembling in her under firm control.

Conceal. Don't feel.

"On the mission you sent her on? All the way to Corona? "

"She is a capable child."

"Her opponent is the Northern Beast. Capable does not cut it, especially without back up." She lifted her chin up and dared him to disagree with her.

He simply chuckled before turning around to exit the hangar.

"Fret not, Enforcer Thirteen." He paused before smiling. "Elsa."

His smile sent shivers down her spine while he left as silent as he came. She clenched her fist as she was struck with the feeling that there was more going on than met the eye. Lifting her gaze to the horizon she whispered to her sister on the breeze.

"Godspeed, Demon of Slaughter. "

Come back to me.
