Star Trek the Next Generation - Narrator's Toolkit

(from the book):

Any Star trek game session is only as good as the Narrator who runs it. In the Star Trek: The Next Generation Roleplaying Game, the Narrator acts as director, producer and writer, in addition to playing the roles of the entire supporting cast. While this may seem daunting at first, don't despair; many players find it to be the most challenging and rewarding part of the game.

Includes a 64 page book with tips for the Narrator and a ready-to-run adventure as well as a 3-page Narrator screen with charts and tables.
