From the introduction: "Nightventure is a series of 'one-night' scenarios designed to be used
in conjunction with existing fantasy role-playing systems. As such, none of the scenarios stand
as a game alone, but as a single, focused definition . . . an application of the game theory set
forth in those other works." (Thanks to Kynan Connor, USA for this information)
This is the original published version of Rahasia (Indonesian for 'secret') which was later purchased,
revised and republished by TSR twice with the same name (RPGA1 and B7) Rahasia is currently at a higher value then its brother
Pharoah probably due to less frequency in auction.
Features: Rahasia Background Story, Map of Temple Area, Map from Father's Papers, Player Objectives,
Story Overview, Objectives and Awards, Rahasia Dungeonary, Notes to the Referee, Outdoor Description and Optional Game Endings.
