The ability to feel connected is something that we are neurologically coded to do, interact and connect, Astartes are no different. They connect to their brothers, to their squads and feel many of the same emotions that we do.
But one thing that I have become very interested in is how the Astartes connect to mortals, what motivates them to do so. Honour? Duty? But what else. The original definition of courage is to tell your story with your whole heart, courage is to dare to be imperfect.
So how do Astartes view their own imperfections when their culture is so much about perfection. So how do do they struggle with these things, with vulnerability, shame, knowing no fear. What does it mean to them?
Do you deal with these things, with belonging and family and sense of unity in your game, have you thought about exploring these things in your game? What does transhumanism mean?
