User summary: Darrians: The Secret of the Star Trigger is a Traveller Alien Module set in a small backwater confederation. When the Darrians were about to produce stelar flares in their own star, they stumbled upon the secret of the star trigger. However, the flares devastated their civilization, requiring centuries for them to rebuild. When faced with aggression, they dug out the out technology.
The module includes information about history, culture, character generation, language development, an adventure, along with maps, illustrations, and charts.
Note: This was supposedly the last Classic Traveller Alien Module, and the only one to cover a minor race.
