“ONCE YOU HAVE ELIMINATED THE IMPOSSIBLE, WHATEVER REMAINS,
HOWEVER IMPROBABLE, MUST BE THE TRUTH.”

– COMMANDER SPOCK

The Keyhole of Eternity is a three-part campaign, previously only available as part of the Star Trek Adventures Tricorder Collector’s Box Set.

The players’ shore leave at the independent colony of Hefner Bay is cancelled when a damaged Klingon warship approaches. Soon, unexplained phenomena begin to occur on the players’ ship, the planet surface, and at the edge of the system. Can the crew protect the system and its millions of inhabitants, or are their efforts just making things worse…?

The 44-page PDF mini-campaign was written with the original series era in mind, but can be easily placed in any era of Star Trek with minimal revision.

Over the course of this campaign, players will have the opportunity to:

• Investigate anomalies on the planet, on the players’ ship, and within the system.
• Encounter Orion privateers.
• Engage with the concepts of string theory.
• Discover a previously unknown inter-dimensional alien species, the Gih*Tchu*Nee.
• Defend the population of Hefner Bay from destruction.
