Enrique Oscuro

"Listen, Shinigami. The "power" you hold is trivial in a place that relies solely on the strength of others to create a civilization. Do you have the raw power to subdue anyone in your range of sight? Do you hold the instinct required to intimidate legions of cannibalistic beasts? Do you possess the immorality that will allow you to slash away at your own subordinates? Hmm...it seems that you do possess these attributes. Perfect. You wish to lead? I can grant you the army you wish. After all, I'm only a shadow within this vast desert. Plant your forces anywhere, exert all the power you wish, but remember one thing; you will never catch my shadow."
