Really short story. Inspired by a picture I found...
Loki stepped out of the rubble. The muzzle he once wore was crumpled in his cold hands. Dust and ash clocked the air, making the air thick and almost unbreathable. He shook his head, and bits of stone fell from his face.
He turned. Why... How? His home was gone, obliterated. Reluctant tears leaked from his emerald green eyes. Loki shook his head. No. He would not cry. Throwing the mask aside, he turned away from the wreak.
As he trudged over the landscape, a small trail of blood and tears marked his path. Thor. He was gone. Gone. Loki's eyes grew wide in realization and horror. Thor. Gone. Forever. He clutched at his hair an fell to his knees devastated.
"Impossible. He-" A scream ripped from his mouth, letting the world know of his sudden sorrow and terror. Was he next?
Of course. Of course he was! Loki laughed, and madness began to find it's way into his eyes. His hands twitched as he rose, and a broad, crazed smile was upon his cracked lips.
"Come get me."
