Thank you for reading and commenting. :)
I just thought the sole survivor is a commonly used term (apparently also used to refer to the player character in Fallout 4).
The companion cards should be placed in the middle of the table, and the current Sol player can use them.
There was only so much I can put in 200 words, and I hoped that everyone has some GMing experience to generate encounters using the prompts available. I appreciate your critique. I will add rules/advice for the narrator to structure a round/episode, when I write the extended rules after the voting finishes.
