How to use the plot elements of Star Trek: TNG's Heart of Glory in a TTRPG
This ep in TNG did a lot of lore-building for the TNG version of Klingons. But that means the main plot is actually pretty simple. It's kind of like a fetch quest.... except you have to do investigation when you get there to figure out WHY you ever got the quest at all.
It also goes with the idea that being an "honorable warrior".... doesn't make you a good person, or even legally acceptable. The Talarians, and even Klingons think these guys were criminal scum. That's despite how they do in fact conduct themselves in many ways like the actual idea of what an "honorable warrior" is. They DON'T actually murder-hobo random people. But they do have terrible reasons for the times when they do choose to fight.
Also.... we know they're liars. Many of the things they claim are completely false and just a cover story. THEY disabled then boarded the Batris and when Picard asked what happened they told him they'd booked passage as passengers. Why? to deceive him into not holding them accountable for their crimes. Would your party fall for their lies?
