Trivia

 * There are wild stories that these creatures are no longer seen as a result of being laughed at by an indiscreet stalker, but this is unsubstantiated and should be considered as braggadocio.
 * In LADC their telepathic abilities could be difficult to deal with early in the game.
 * There are some loud strange sounds after you found wounded Stalker and visit Bandit Mine.
