Playing a Vargr would work well in this one. Go ahead any generate one. He can be a passenger on the ship. I will figure out a way to weave him into the story.
In thinking about it, he could have some knowledge of the chief antagonist of the adventure, who is also a Vargr. He might tag along with the group to help them out.
You are free to generate from any career field. A space career (merchant, corsair, navy, emissary, belter, or , loner) would work best. Use either the CT Vargr Alien module to generate or DGP Vilani and Vargr.
Just send me a text file when complete.
