Evil grows darkest in the shadow. This chapter comes to its evil conclusion with Heretic: Shadow of the Serpent Riders. In a twisted medieval dimension, undead creatures and bestial horrors have done the unthinkable - callously slaughtering your entire race. But the nightmare has just begun. Wielding ungodly weapons such as the Firemace or Hellstaff and casting spells from the tomes of power, you must seek your vengeance... or die trying.
