Inspired by Brandon Sanderson's Mistborn series.
"Kelsier had heard stories.
He had heard whispers of times when once, long ago, the sun had not been red. Times when the sky hadn’t been clogged by smoke and ash, when plants hadn’t struggled to grow and when skaa hadn’t been slaves. Times before the Lord Ruler. Those days, however, were nearly forgotten. Even the legends were growing vague." -Mistborn Prologue
