Of the Night Stalker, there is no history, only stories. There are ancient tales woven into the lore of every race and every culture, of an impossible time before sunlight and daytime, when night reigned alone and the world was covered with the creatures of darkness--creatures like Balanar the Night Stalker.
It is said that on the dawn of the First Day, all the night creatures perished. All, that is, save one. Evil's embodiment, Night Stalker delights in his malevolence. He created the primal role of the Night Terror, the Boogeyman, and as long as there have been younglings, his is the specter summoned to terrify them. This is a role he relishes; nor are these empty theatrics. He does indeed stalk the unwary, the defenseless, those who have strayed beyond the lighted paths or denied the warnings of their communities. Night Stalker serves as living proof that every child's worst nightmare....is true.
