It is possible to kill several of the game's civilian non-player characters, whereas in every other Infocom or Zork game, such actions are either impossible to accomplish or immediately punished by death. Killing causes a masked vigilante who is also the "Guardian" to come and remove all the player's items, with the intention of rendering the game unwinnable. As in the "Zork" text-adventure games, there are several ways to make the game unwinnable by using or altering an object or item in an unintended manner.
