I have a little question
How is working, that your goal is to destroy the nomads OR make peace with them,
and at the same time, one of the goals is to defend Sirius at all costs.
How will you be able to use the option "Make Peace" with nomads while their intentions are very clear, which is destroying man-kind (Sirius).
Good luck with the group, and it's good to see new ideas
EDIT: apologies, i did the usual mistake and posted using wrong nickname, so @Xenon here
