Harbinger
By SMYGO4EVA
The things in her nightmares were always dark, and eyes glowing in a baleful light. They walk like humans, two-legged: shaped of metal and an oily darkness, wearing masks where their faces should be.
Korra would wake up shuddering, at the relentless sounds their metallic steps make; to her, they sounded like chains. Water, the very lifeblood of Earth, was the only thing that calmed her; her flesh-and-bone elements were nothing like the cloaked and wandering fiends of her darkest dreams.
The odd relief she felt to find the powers of bending was explained when she is again faced with the Equalists, and her ears fill with chains and armor.
