Here is a complete mission for gamemasters to use with their players. I would love to hear feedback from anyone who plays it!
The characters are mapping a trinary star system deep within the Shackleton Expanse when they detect an alien spaceship listing in space. The pre-warp vessel, a ceremonial yacht of some sorts, is found to contain two unconscious and one dead alien. Also, the ship’s nuclear-powered engine is about to fail. The crew is forced to evacuate the aliens before the ship explodes.
Upon bringing the aliens to consciousness, the crew learns that the two survivors, a male and female, are engaged to be married. They were on their way to becoming ceremonially bonded when their space yacht’s engine failed. They are both members of the Roord race, though they hail from two different planets located in the trinary star system. They are members of their respective royal family. Tradition dictates that they must make the journey to exact spatial coordinates to perform the ceremony since their marriage can only be satisfied by planetary and solar alignment. Another problem surfaces when the crew learns that the third deceased alien was the only person capable of performing the ceremony. The ceremony requires the master of a vessel to consecrate the betrothal.
The crew comes to appreciate that the Roord must adhere to strict rules to solemnize their marriage. Otherwise, they must wait another twenty years to wed. In addition, their marriage is needed to prevent a war from continuing on their homeworld, a conflict that has been going on for one hundred and twenty years. With a ready starship and able captain, the crew surmises that they could help make this wedding happen. It would not be a violation of the Prime Directive since the Roord are aware that there are other space-faring species (even though they have not achieved warp travel yet) nor is it unheard of that a non-Roord performs the peacekeeping ceremony.
Wedding bells start to ring. However, rival Roord factions are eager to continue the war. They arrive to disrupt the ceremony. Can the crew hold off the wedding crashers, perform a solemn ceremony, and bring peace to this star system?
