Confrontation at Epsilon Alpha III!
When the player characters receive a coded message from the science station at Epsilon Alpha III, they learn of the discovery of a powerful alien energy source. However, the artifact is located in an area sacred to the native inhabitants, who are as yet unaware of the Federation. When the Federation’s adversaries arrive at the planet, also intent on securing the artifact, the player characters must decide how to resolve the impending conflict—by diplomacy, confrontation, or involving the locals and violating the Prime Directive in the process?
