Then the world will be changed irrevocably \-\- but not quite yet\. Pesky human investigators have learned much\. Now they must survive long enough to make sense of what they know, and take resolute action\. Masks of Nyarlathotep\[/b\] is a Lovecraftian exercise in horror and mystery\. This Call of Cthulhu roleplaying classic is a series of linked adventures forming one long and unforgettable campaign\. Horrifying deeds and dangerous sorcery dog those who dare attempt to unravel the fate of the Carlyle Expedition\. Set in 1925, adventures begin in New York, then move overseas to England, Egypt, Kenya Colony, Shanghai, and western Australia\. Such extended globetrotting requires wit and planning by the players\. Their investigators must have steady finances, good language skills, and a willingness to persevere despite governmental interference and cultist harassment\. Meanwhile the keeper must bring to life different exotic locales, recreate the sensibilities of other cultures, and balance non\-player\-character foes and friends to allow each investigator to earn his or her own destiny\-\-ultimate triumph, perhaps, or perhaps madness and agonizing death\.
