The Nighthawks are a guild of assassins who have crept about in Midkemia for several centuries, though they have only truly organized themselves in the past hundred years. They dress for concealment under the cover of night, so they tend toward entirely black wardrobes. Nighthawks have been known to turn into Black Slayers. Black Slayers are “undead” zombie-like creatures that have been brought back to life by evil means. Once killed, they will continue to rise until a spellcaster casts the “Final Rest” spell on them.
