The Nine Wars
In the midst of the Nine Wars, Lady Sif's sword shattered upon impact with the ax of a Salver Beast, a gruesome being whose ways are vicious and bloodthirsty. The creature shoved her to the ground, robbed her of her dagger, and swung his ax.
However, a gurgled roar filled the battlefield and a white flash, like that of lightning, overwhelmed the skies. The beast was dead; and a man, wielding an orb of light within his palm, proudly stood upon it.
"Thor?" Sif questioned. But upon the man's snicker, she recoiled into her memories of a mischievous soul, Loki.
